• How to Adjust Toilet Flush Valve Water Volume?

  Nov 25, 2025

  During daily use, many users encounter weak flush power, high water usage, incomplete waste removal. These issues often signal that the flush valve inside the toilet tank requires a new water volume setting. Although toilet structures vary, most household toilets share similar logic for flush volume adjustment. This guide explains core principles, adjustment methods, and practical checks that help complete the process in 2–3 minutes.   1. Why Adjust Flush Valve Water Volume?   You may need to adjust flush volume in the following situations: l  Weak flush performance：Low water level or low discharge volume may reduce siphon strength. l  High water consumption：Toilet tank drains unnecessary amounts during every flush. l  New flush valve replacement：Height difference between old and new valve requires a new water level setting. l  Water saving demand：Half flush and full flush need minimum water while still achieving effective flushing.   2. Key Principles That Influence Flush Volume   Flush volume depends on several internal elements: l  Overflow tube height：Controls maximum water line inside the tank. l  Half flush float height：Controls half flush water volume. l  Full flush adjustment plate opening：Controls full flush water volume.   3. How to Adjust Flush Valve Water Volume?   1）Adjust Overflow Tube Height   Overflow tube height sets maximum tank water level, which defines maximum available flush volume. This method becomes the simplest adjustment for single flush push button flush valves. For canister-type flush valves, this method works together with additional components for finer adjustment.   2）Adjust Half Flush and Full Flush Water Ratio   Most canister-style dual flush valves support independent adjustment for half flush water volume and full flush water volume.   (1) Half Flush Adjustment   Half flush adjustment has two methods: direct movement for the half flush float height, or indirect adjustment through a top knob on the flush valve. l  Half flush float moves upward → half flush water volume becomes lower l  Half flush float moves downward → half flush water volume becomes higher   (2) Full Flush Adjustment   Full flush adjustment usually relies on an adjustment plate located at the bottom area for the flush valve. This adjustment plate controls the release speed inside the full flush chamber. When water inside the full flush chamber drains out completely, the full flush float drops under gravity and shuts the outlet, ending the full flush. Therefore, the release speed inside the full flush chamber decides full flush duration: l  Longer duration → higher full flush water volume l  Shorter duration → lower full flush water volume When the opening window controlled by the full flush adjustment plate becomes larger, full flush water volume becomes lower. When the opening window becomes smaller, full flush water volume becomes higher.   4. How to Confirm Best Flush Volume?   Perform multiple flush tests: l  A small paper group inside the toilet bowl drains smoothly l  Waste removal completes in one flush l  Half flush meets water saving demand l  No overflow and no leakage inside the tank If all checks pass, the flush valve reaches an optimal setting.   5. Summary   Flush valve adjustment focuses on three essential steps: l  Set overflow tube height around 2–3 cm below tank rim l  Adjust half flush and full flush opening sizes l  Raise or lower water level to control flush strength A short adjustment process upgrades flush performance and improves water efficiency for everyday use.

• How to Adjust Water Fill Valve in Toilet Tank?

  Nov 21, 2025

  Why Do You Need to Adjust the Toilet Fill Valve?   We often need to adjust the working water level when the toilet tank shows one of the following issues: Water level too high: When the water level rises above the overflow tube of the flush valve, water keeps flowing into the overflow tube. The fill valve cannot reach the shut-off point and continues running, causing water waste and increasing household water bills. Water level too low: The tank cannot store enough water to create a strong siphon in the toilet bowl. This results in weak flushing and poor waste removal. Height mismatch after installation or replacement: When a new fill valve is installed, its height must match the old one. Both the main body and the float position should be adjusted to a similar level. Water-saving needs or different toilet designs: Toilet tanks vary: some are tall and narrow, some are short and wide. You may need several adjustments to find the level that provides strong flushing power while saving water.   2. Two Common Types of Toilet Fill Valves   Float-ball fill valve: It uses a lever with a float ball to sense water level changes. As the float rises, it pushes the lever to stop water flow. However, it takes up a lot of space in the tank. Float-cup fill valve: This modern, space-saving design is the mainstream option for most toilet tank systems today. The dual-float structure helps maintain stable refill speed and ensures quick shut-off when the water level is reached.   3. Preparations Before Adjusting the Fill Valve   Turn off the water supply (angle valve). Remove the toilet tank lid. Confirm the type and structure of your fill valve. Locate the adjustment mechanism: screw, sliding rod, float clip, or adjustment tab.   4. How to Adjust the Toilet Fill Valve?   1) Float-cup Fill Valve (Mainstream Design) Coarse adjustment: Most adjustable fill valves consist of two sections. Remove the locking clip or pin between them to raise or lower the valve height when the difference between actual and desired water level is large. Fine adjustment: Locate the adjustment screw or lever near the float cup and turn it clockwise or counterclockwise to fine-tune the water level. Note: Some designs adjust only the inner float height. After that, make sure the outer float is also set to the same height. Water level reference: Fill until the water reaches the tank mark or sits about 1.5cm below the top of the overflow tube.   2) Float-ball Fill Valve (Traditional Design) Coarse adjustment: Metal rods can be bent slightly to raise or lower the water level. For plastic-rod designs, loosen the knob at the joint area to adjust the float height. Fine adjustment: Some float balls can be screwed upward or downward to fine-tune the water level. Water level reference: Same as above—tank mark or about 1.5cm below the overflow tube top.   5. How to Test After Adjustment   Turn on the water supply and let the tank refill. Check if the water reaches the correct level marking. Inspect the fill valve base and connections for leakage. Listen to the refill sound: a good valve should stop instantly without dripping. Flush to confirm strong siphon and smooth waste removal in the toilet bowl. Run 3–5 cycles to ensure stable water level and proper shut-off.   6. Conclusion   1) Choose a height-adjustable and high-compatibility toilet fill valve. 2) Select quiet-refill and water-saving certified products for better performance and lower long-term water cost. 3) Jielin Plumbing Fill Valve Advantages: 3-year warranty and durable construction Multi-level height adjustment compatible with most toilet tank designs Quick shut-off technology for stable water level 4) Water level adjustment is simple and easy for most users. 5) Proper adjustment improves flushing power and reduces water waste. 6) Replace the fill valve when it becomes noisy, unstable, or difficult to adjust.

• Does a Basin Need an Overflow?

  Nov 14, 2025

  In the early days of bathroom product design, the overflow hole was a standard feature on nearly every basin. The purpose was simple: when users forgot to turn off the faucet or when water drained too slowly, the overflow allowed excess water to return to the drain—clearly showing the benefits of a basin overflow hole in preventing flooding and water damage.   As home safety awareness increased, the overflow hole became widely viewed as a basic protective feature.   Why Are Many Modern Basins Designed Without an Overflow?   In recent years, more designers and hotels have adopted the modern bathroom basin without overflow. Several factors drive this trend:   1. Cleaner, Minimalist Appearance A basin without an overflow offers smoother lines and a unified surface, ideal for contemporary minimalist bathrooms.   2. Easier to Clean, No Hidden Hygiene Problems The overflow tunnel is narrow and deep, often trapping dirt and odors. This is one of the common disvantages of basins without overflow, but for many homeowners, removing this tunnel makes the basin easier to clean overall.   3. Practical for Countertop Vessel Basins Many vessel basins are deep bowl structures, meaning the overflow would have limited function. Manufacturers often remove it to simplify the design.   4. Material Limitations of Stone Basins A stone basin without overflow design is typically carved from a solid block. Since it’s impossible to drill a curved internal overflow channel through stone, this material naturally leads to no-overflow basin models.   5. Ceramic Basins Still Support Overflow In contrast, ceramic basin with overflow design remains common because ceramic molds can easily incorporate an internal overflow channel during production.   So, Do You Need an Overflow?   Both options are suitable; it simply depends on your household and usage habits. ✔ Basins With Overflow: Safer Ideal for families—often considered the best design type for homes with kids Prevents accidental flooding Offers buffer time if someone forgets to turn off the faucet ✔ Basins Without Overflow: More Stylish A clean, hole-free surface Strong design identity in modern bathrooms Easier to wipe and maintain   Conclusion   Does a basin need an overflow? The answer: It depends on your priorities—there’s no right or wrong. Prefer safety and peace of mind? Choose a basin with an overflow Prefer clean aesthetics and modern simplicity? Go with a no-overflow design Either choice works well when paired with the right pop-up drain and accessories. If you ever need basin overflow ring replacement, no-overflow pop-up drains, or other basin fittings, Jielin Plumbing provides a full range of solutions for both overflow and no-overflow basins.

• How to Replace Toilet Flush Handle?

  Nov 04, 2025

  In everyday use, the toilet flush handle is one of the most frequently operated parts of a toilet. Over time, it may become loose, broken, or stuck, which can prevent the toilet from flushing properly. Fortunately, replacing a toilet flush handle is quite simple — with just a few basic tools, the whole process can be completed within minutes. This article will walk you through the detailed steps and precautions for toilet flush handle replacement.   1. Prepare Tools and Materials   Before starting, make sure you have the following items ready: New flush handle (Toilet Tank Handle): Confirm whether it’s a side-mount or front-mount type, and make sure it matches the hole size on your toilet tank. Wrench or pliers: These are useful for removing the old handle nut, especially if the nut has become tight or corroded over time.   2. Remove the Old Flush Handle   Turn off the water supply and empty the tank Turn the shut-off valve clockwise to close the water supply, then press the handle to drain all the water from the tank.   Remove the tank lid Carefully take off the ceramic or plastic lid and place it somewhere safe to avoid damage.   Detach the chain Disconnect the chain attached to the handle lever and hang it temporarily on the overflow tube of the flush valve.   Loosen the mounting nut The handle is usually secured inside the tank with a plastic nut. Note that this nut is reverse-threaded, meaning you’ll need to turn it clockwise to loosen it.   Take out the old handle assembly Once the nut is loose, remove the handle and lever assembly from the outside of the tank.   3. Install the New Flush Handle   Insert the new handle into the hole From the outside of the tank, insert the new handle into the original hole. Make sure it faces the correct direction (upward or sideways).   Tighten the mounting nut From inside the tank, hand-tighten the nut counterclockwise. Do not overtighten, as it could crack the plastic nut.   Connect the lever to the flush chain Attach the new handle’s lever to the flush chain inside the tank. The chain length should be moderate — if it’s too long, flushing may be weak; if too short, water may continuously leak. A useful tip: pull the chain straight to compare with the lever length, then adjust the hook position before attaching it.   4. Test and Adjust   Turn on the shut-off valve and let the tank refill. Press the handle to check if the flush is smooth and if the flapper closes completely. If the flush is weak or the water keeps running, adjust the chain length or handle angle as needed.   5. Maintenance Tips   Avoid pressing the handle too forcefully. Check the mounting nut periodically to ensure it’s secure. Replace the handle if it becomes rusty (for metal ones) or brittle (for plastic ones) to keep the flushing system working properly.   Conclusion   Replacing a toilet flush handle is a simple yet useful home maintenance skill. With just a few easy steps, you can restore your toilet to normal operation.

• How to Flush a Toilet with Two Buttons?

  Oct 28, 2025

  The dual flush toilet has become widely used for its water-saving and efficient performance. Compared with traditional single-button toilets, a two button toilet flush allows users to choose different flush volumes according to their needs, helping to conserve water and reduce waste. However, many people still don’t know the difference between the two buttons. They often press both at the same time, which can still flush the toilet but eliminates the water-saving advantage of the design. So how should you properly use a dual flush toilet? Let’s take a closer look.   1. Understanding the Structure of a Dual Flush Toilet   A two button toilet typically has two buttons of different sizes: Small button (Half Flush): Used to flush liquid waste, usually with less water (around 3 liters). Large button (Full Flush): Used to flush solid waste, using more water (around 6 liters). These two functions are controlled by a dual flush valve inside the cistern. Each button activates a different discharge path, allowing a balance between water conservation and flushing power.   2. How to Use the Two Buttons Correctly     Choose the right button for each use:   For liquid waste, press the half flush button lightly to complete a small flush. For solid waste or when more paper is used, press the full flush button for a stronger flush.     Press firmly and release quickly:Light or hesitant pressing may result in incomplete flushing or the button getting stuck.Press the button evenly and release it quickly so that the flush valve can open and close properly.Especially when using the half flush function, a quick release is important — if you hold it down too long, the system will perform a full flush instead, losing its water-saving effect.     Keep the buttons and cover clean:Over time, limescale or dust can affect button sensitivity. Wipe the surface regularly with a damp cloth to maintain smooth and responsive operation.   3. What to Do If the Dual Buttons Don’t Work   If you notice: The button doesn’t respond or gets stuck The flush is weak or incomplete Water keeps running continuously Flushing stops immediately after releasing the button These issues are often caused by an aged flush valve, sticking buttons, or worn seals. You can try the following: Check if the button assembly is loose. Remove the tank lid and press or lift the dual flush valve manually to see if it functions properly. If damaged, replace it with a compatible flush button or dual flush valve kit of similar size. 4. Water-Saving Tips   The greatest benefit of a dual flush toilet is water efficiency. According to tests, proper use of a dual flush system can save thousands of liters of water each year. Learning how to use a dual flush toilet correctly not only reduces your water bills but also helps protect the environment.

• How Long Does a Toilet Flapper Last?

  Oct 21, 2025

  In daily life, the toilet is one of the most frequently used fixtures in every home, and the toilet flapper is one of its most important yet often overlooked components. It’s commonly found in lever-operated toilets, which are very popular in the U.S. market.   The toilet flapper controls the water release from the tank. When you press the flush handle, the flapper lifts up, allowing water to flow into the bowl. After flushing, it falls back down to seal the outlet. However, when the flapper becomes old or damaged, it can cause continuous leaking or weak flushing. So, the question is — how long does a toilet flapper actually last?   1. Average Lifespan of a Toilet Flapper   Generally, a high-quality toilet flapper lasts about 3 to 5 years. However, this can vary depending on factors such as environment, water quality, and material type. For example:   Hard water with high mineral content can cause limescale buildup and speed up rubber aging.   Improper use of cleaning tablets, especially blue ones placed directly inside the tank, can corrode the rubber over time.   Frequent use means more open-and-close cycles, resulting in faster wear.   Toilet flappers are typically made from PVC, rubber, or silicone.   PVC flappers have the shortest lifespan (around 2–3 years) but are low cost.   Rubber and silicone flappers offer similar durability and better resistance to aging and corrosion.   If your toilet is used often, it’s recommended to check the flapper’s seal every 2 to 3 years.   2. Common Signs of a Worn-Out Flapper   When a flapper starts to deteriorate or loses its seal, you may notice one or more of these issues:   1) Constant leaking from the tank – You can hear water running even when the toilet hasn’t been flushed. This means the seal is seriously worn and needs immediate replacement.   2) Frequent refilling sounds – The tank water level keeps dropping, causing the fill valve to refill repeatedly.   3) Deformed or sticky flapper surface – Caused by aging, hardening, or chemical corrosion.   4) Incomplete flushing – The flapper doesn’t lift or drop properly, reducing flushing efficiency.   If any of these occur, it’s time to replace your toilet flapper.   3. How to Extend the Flapper’s Lifespan   To make your toilet flapper last longer, consider the following tips:   Choose quality materials: Opt for silicone or high-grade rubber flappers that resist corrosion and aging.   Avoid harsh cleaning agents: Especially those dropped directly into the tank. Instead, use a refill cleaner box that releases detergent through the overflow pipe, preventing direct contact between the cleaner and the flapper.   Clean the tank regularly: Remove limescale and debris to keep the interior clean.   Inspect regularly: Check for leaks and replace the flapper promptly to prevent water waste.   4. Conclusion   Although it’s a small part, the toilet flapper plays a crucial role in the overall function and water efficiency of your toilet. Replacing it every 3 to 5 years ensures smooth flushing performance and helps avoid costly leaks.   If you’re looking for high-quality, durable toilet flappers, welcome to contact Xiamen Jielin Plumbing Co., Ltd. — a professional manufacturer specializing in toilet tank fittings. We offer a wide range of flapper sizes, materials, and designs compatible with major toilet brands to meet the needs of customers worldwide.

• How to Change a Toilet Flush Valve?

  Oct 16, 2025

  1. Prepare Tools and Materials   Before starting, make sure you have the following items ready:   1) New Toilet Flush Valve (Flush Valve or Dual Flush Valve) When purchasing a new flush valve, ensure the size and model match your toilet. The most common sizes are 2-inch and 3-inch, which can be determined by the diameter of the old valve’s outlet. Also, check whether your toilet is two-piece or one-piece. For two-piece toilets, choose a flush valve that uses a locknut to secure it. For one-piece toilets, select a model that uses a steel bracket for tightening.   2) Adjustable Wrench For two-piece toilets, the locknut at the bottom of the tank may be hard to remove by hand, so a wrench will help you loosen it.   3) Screwdriver For one-piece toilets, use a screwdriver to loosen the central screw inside the tank that holds the flush valve.   2. Step-by-Step Replacement Guide   1) Shut Off the Water Supply and Drain the Tank Turn the angle valve clockwise to stop water flow. Press the flush button (for dual flush valves, press the full flush button) to completely drain the tank.   2) Remove the Old Flush Valve For two-piece toilets, use a wrench to loosen the locknuts connecting the tank and the bowl, then carefully remove the tank. Next, detach the old flush valve assembly from the tank bottom. For one-piece toilets, simply unscrew the central fixing screw inside the tank to remove the valve.   3) Install the New Flush Valve Insert the new valve into the mounting hole at the tank bottom. Adjust its position so the rubber gasket fits tightly. Tighten the locknut or bracket securely—but avoid over-tightening.   4) Reinstall the Tank and Reconnect the Water Supply Line For two-piece toilets, position the tank back in place and align the bolt holes. Tighten the bolts evenly. Reconnect the water supply hose, ensuring a proper seal at each joint.   5) Test for Leaks and Flush Performance Turn on the angle valve to refill the tank. Check the bottom for any leaks and test the flush button. If the flushing system runs smoothly with no leaks, your installation is successful.   3. Tips to Extend the Flush Valve’s Lifespan   1) Choose high-quality materials such as ABS, POM, or PVC for better durability and anti-aging performance.   2) Clean the inside of the toilet tank regularly to prevent scale and debris from affecting the seal.   3) Replace toilet tank fittings every 3–5 years to maintain optimal flushing and prevent hidden leaks.   4. Conclusion   Replacing a toilet flush valve is a simple but essential maintenance task. By following the correct steps, you can make your toilet work like new again. If you are unsure which flush valve model to choose, check the toilet brand manual or look up related installation videos online. As a professional manufacturer of toilet tank fittings, Xiamen Jielin Plumbing Co., Ltd. provides a wide range of flush valves, fill valves, push buttons, and accessories.

• How to Install Toilet Fill Valve?

  Oct 07, 2025

  In daily life, if your toilet tank fills slowly or does not refill at all, it usually means the toilet fill valve has worn out or failed. Replacing it with a new one can restore normal flushing performance. Fortunately, toilet fill valve installation is quite simple—just follow the correct steps carefully.   Preparation Before Installation   Before installing the new toilet fill valve, make sure to: 1. Turn off the water supply – Rotate the shut-off valve clockwise to stop the water flow. 2. Empty the tank – Press the flush button to drain all the water from the toilet tank. 3. Remove the old fill valve – Use a wrench to loosen the locknut at the tank bottom and detach the old fill valve and supply hose. 4. Choose the right replacement fill valve – Ensure the thread type and size match your region’s water supply connector for a leak-free fit. Europe and Africa: G3/8 Middle East: G3/8 and G1/2 Asia and South America: G1/2 Peru: G7/8 or 15/16-14NPSM North America: 15/16-14NPSM Once everything is ready, you can proceed to install the new fill valve.   Installing the New Fill Valve   1. Adjust the fill valve height    Most fill valves consist of two sections connected by a locking clip. Before installation, adjust the height according to your old valve or the tank size to ensure proper water level control. 2. Set the float height    The float can be adjusted by rotating the adjustment rod or sliding the clip. The highest water level (shut-off point) should be about 15 mm below the top of the overflow tube.    If it’s too high, water will flow into the overflow tube continuously; if too low, flushing performance will be weak. 3. Insert the new valve into the tank    Insert the valve through the bottom hole of the tank. Make sure the rubber seal sits tightly against the inner wall to prevent leaks. 4. Tighten the locknut    From the outside of the tank, tighten the plastic nut by hand or with a wrench—but do not overtighten, as it may damage the threads or crack the tank, making future replacement difficult. 5. Reconnect the water supply hose    Attach the hose to the valve’s threaded inlet and ensure the connection is firm. 6. Install the refill tube    Connect one end of the refill tube to the fill valve outlet and the other to the overflow pipe on the flush valve. Make sure both ends are securely fitted.   Test for Leaks and Function   1. Turn on the water supply to let water fill the tank. 2. Check for leaks – Pay special attention to the seal at the base of the fill valve. 3. Confirm proper water level – The water should stop filling just below the overflow tube’s top. If any leakage occurs, slightly tighten the locknut or re-position the rubber seal.   Summary   Installing a toilet fill valve can be summarized in five simple steps: > Remove → Insert → Adjust → Secure → Test As long as the seal is tight, the float height is set correctly, and all joints are leak-free, the new fill valve will work reliably for years. For better performance, consider choosing a quiet fill valve or one with an adjustable height design, which helps reduce noise and improve water efficiency.

• How Does a Basin Without Overflow Work?

  Sep 23, 2025

    In daily life, most wash basins are equipped with an overflow hole. The overflow’s main function is to allow excess water to drain away when the tap is accidentally left running or the water flow is too strong, preventing the basin from overflowing and flooding the bathroom.   However, many modern bathrooms now feature basins without overflow holes. These basins have unique design features and usage habits. So, how exactly does a basin without overflow work?   1. Working Principle of a Basin Without Overflow   Just like all wash basins, water enters through the faucet and drains away through the basin waste. The difference is that a non-overflow basin must use a basin waste without overflow, which is specially designed to work without the extra overflow channel. This type of waste ensures proper sealing and smooth drainage, even though there is no overflow hole.   Because there is no overflow for basin, preventing bathroom flooding depends entirely on the user’s habits — such as turning off the faucet after use and making sure the basin waste is opened during drainage.   2. Advantages of a Basin Without Overflow   1) Aesthetic Design A basin without overflow offers a cleaner, more minimal look, which is ideal for modern and minimalist bathrooms. Many new bathroom designs adopt non-overflow basins because they can be made thinner and lighter. Without the need for a hole, natural stone basins such as granite and marble can also be used. The unique stone patterns can better match different bathroom styles.   2) More Hygienic Since there is no overflow channel, there is no hidden space for dirt, bacteria, or mold to accumulate. Compared with a sink basin overflow cover, which is sometimes hard to clean, a non-overflow basin is easier to maintain on a daily basis.   3) Flexible Installation In smaller or custom bathroom spaces, non-overflow basins are easier to fit into different countertop layouts without worrying about matching an overflow trim.   3. Things to Keep in Mind   1) Preventing Overflow Always remember to close the tap and open the basin waste when in use. In households with children or elderly people, extra care should be taken to avoid flooding accidents.   2) Choosing the Right Basin Waste Always pair the basin with a basin waste without overflow to ensure proper drainage and sealing.   3) Application Scenarios A non-overflow basin is more suitable for design-oriented bathrooms or spaces where users have good usage habits. If you worry about flooding, a traditional basin with a wash basin overflow cover, wash basin overflow ring, or basin sink overflow trim may still be the safer choice.

• How to Fix a Toilet Leaking Even with New Flapper ?

  Sep 16, 2025

    In daily life, a leaking toilet is a common problem. Since the flapper is one of the parts that ages most easily, many people first choose to replace it. However, sometimes even with a new flapper, the toilet still leaks. If this happens, it usually means the problem is not only with the flapper itself. This article explains the most common causes and solutions to help you fix the issue thoroughly.   1. Confirm the Flapper Is Installed Correctly   Even if you have a new flapper, there can still be issues:   Check the size: Different toilets require different flapper diameters, most commonly 2 inch toilet flapper replacement or 3 inch toilet flapper replacement. If the size does not match, for example using a 2-inch flapper on a 3-inch flush valve, the seal cannot be completely tight, leading to toilet flapper leaking after replacement.   Ensure the position is aligned: The flapper must fall directly into the center of the flush valve seat, otherwise water may leak from the edges.   Check chain tension: If the chain is too tight, the flapper cannot fully close; if it is too loose, flushing becomes ineffective. The best method is to let the flapper close first, then measure and adjust the chain length.   2. Inspect the Flush Valve Condition   Cracks or damage: Even with a new flapper, if the flush valve or overflow tube has cracks, water will still leak into the bowl. In such cases, the entire flush valve needs replacement.   Loose flush valve base: Shake the flush valve gently to see if it is firmly installed. If loose, water can leak between the flush valve base and the tank. Tighten it and check again to ensure no further leakage.   Scale buildup on the valve seat: In areas with hard water, mineral deposits can build up around the flush valve seat, preventing the flapper from sealing properly. Clean the seat regularly with a brush or scrub pad.   If these issues exist, you may find your replaced flapper toilet still leaking or a leaking toilet flapper replaced still leaking situation.   3. Check the Fill Valve Water Level   If the fill valve is set too high, the water level in the tank may rise above the overflow tube. This allows water to continuously flow into the toilet bowl, and the fill valve will keep running because it never reaches the shut-off point. This often looks like the toilet still running after replacing flapper.   Solution: Adjust the float on the fill valve so the water level stays about 15 mm (about half an inch) below the top of the overflow tube. Be careful not to set the level too low, as insufficient water will cause weak flushing.   Conclusion   If your toilet flapper is leaking after replacement, check in order: the flapper itself, the flush valve, and the fill valve. By carefully inspecting each component and addressing the problem step by step, most cases of toilet still leaking after replacing flapper can be solved quickly and effectively.

• How to Measure Toilet Flush Button ?

  Sep 11, 2025

  Before replacing or purchasing a new toilet flush button, it’s important to take accurate measurements of your toilet tank to ensure a proper fit.   1. Identify the Hole Location   Toilet flush buttons are usually installed in one of two places:   Toilet tank lid hole: This is the most common type. The hole size on the lid typically comes in three standard diameters: 38mm, 48mm, and 58mm. You can use a ruler, tape measure, or caliper to measure the flush button hole size. Once you know the measurement, select the flush button that matches.   Toilet tank side hole: If the flush button is installed on the side of the tank, there’s no need to measure. These are usually cable-operated flush valves, and most toilet side flush buttons available on the market are universal.   2. Measure and Adjust the Flush Button Rod Length   For top push button toilets, measuring the hole diameter alone is not enough—you also need to check and adjust the rod length. The rod included with a new flush button is usually longer than required, as manufacturers design it to fit different types of toilet tanks. You can cut it down to the correct size during installation. Here’s how:   1. Initial measurement: Without installing the button, place the rod directly through the hole on the tank lid until it touches the flush valve at the bottom. Note the part sticking out above the lid.   2. Install and test: Insert the rod into the flush button, then install the button onto the tank lid.   3. Close the lid test: Place the lid back on the tank and check if the rod pushes down on the flush valve even without pressing the button.   4.Trim gradually: If the rod is too long, trim off a small amount. To avoid cutting too short at once, it’s recommended to trim 5–10mm at a time, reinstall, and test again. Repeat until the length is just right.   3. Conclusion   Measuring your toilet flush button size and properly adjusting the rod length ensures you purchase the right replacement and achieve smooth flushing performance. Following these steps will help you install or replace your toilet push button with confidence.

• Why is My Toilet Handle Hard to Flush ?

  Sep 03, 2025

  In daily use, you may sometimes find that your toilet flush handle is stuck or very hard to push down. This issue is not uncommon and usually comes from mechanical problems inside the toilet tank. Let’s look at the common causes and practical solutions.   1.Common Causes   1) Chain Tangling The handle works by pulling a chain that lifts the flush valve. If the chain is tangled, knotted, or jammed, it will make the toilet handle hard to flush and the toilet won’t flush smoothly.   2) Worn-Out Flush Valve or Flapper Over time, the flush valve or flapper can deform, swell, or stick. When the valve doesn’t lift properly, it adds resistance and makes the toilet difficult to flush handle.   3) Sediment or Debris in the Tank Hard water can cause scale buildup or sediment at the bottom of the tank. This can block the flush valve’s movement and make the toilet handle gets stuck more easily.   4) Rust or Loose Handle Assembly Metal toilet handles can rust in the humid environment of a bathroom, making movement stiff. If the handle connection to the tank is loose, it can also create extra resistance when pressing down.   5) Obstruction Between Handle and Tank Components Sometimes the handle may rub against the tank wall, lid, or other internal parts, leading to friction and making the toilet flush handle stuck during operation.   2.Solutions   1) Check the Chain Lift the tank lid and inspect the chain. If it’s too tight or knotted, adjust it to leave some slack so that pressing the handle smoothly lifts the valve.   2) Replace Worn Parts If the flush valve or flapper is old or damaged, replace them promptly. Pairing them with a new toilet handle and chain can restore smooth flushing.   3) Clean the Tank Regularly clean the inside of the tank to remove scale and debris. This not only helps the flush mechanism work smoothly but also extends the lifespan of parts.   4) Maintain or Replace the Handle Press the handle while observing inside the tank to see if it rubs against other parts. If the handle is rusted or broken, it’s best to replace it with a new one.   3.Conclusion   A toilet handle hard to flush is usually a small issue that can be fixed by checking the chain, cleaning the tank, or replacing old parts. If you find it difficult to handle on your own, calling a professional plumber is always a good option. Keeping your toilet parts in good condition saves effort and helps prevent unnecessary water waste.
