  • 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.

  • What is Toilet Flush Valve?
    Aug 26, 2025
    1. Introduction   The toilet is one of the most essential fixtures in our daily life, and its flushing system directly determines how well it performs and how the market values it. Among all components, the toilet flush valve plays a critical role. It determines whether flushing is smooth and whether the toilet can save water efficiently.   2. What is a Toilet Flush Valve?   A toilet flush valve is installed at the bottom of the toilet tank. Its main job is to release water from the tank into the bowl when flushing. When you press the button or pull the handle, the flush valve opens, water rushes out instantly, and when flushing is finished, the valve closes tightly to maintain the water level in the tank.   3. Main Functions of Toilet Flush Valve   Control water flow – releases a large volume of water in seconds to clean the bowl thoroughly.   Maintain sealing – prevents water leakage from the tank, which could otherwise increase household water bills.   Save water – modern flush valves often include half-flush and full-flush options to reduce water usage.   4. Common Types of Toilet Flush Valve   There are several types of toilet flush valve, each with different designs and applications:   1) Flapper Flush Valve (Single Flush Valve)   Simple design, controlled by a rubber flapper that opens and closes the drain hole. Widely used in traditional American toilets.   2) Canister or Bucket Type Flush Valve   One version lifts the entire canister vertically, providing stable, consistent water flow and better sealing. This design is common in Kohler toilet flush valves.   Another version only lifts the bottom seal of the canister, where internal mechanics ensure smooth flushing. This is often used in top-push toilets.   3) Dual Flush Valve   Provides two options: half flush for liquid waste and full flush for solid waste, significantly improving water efficiency.   4) Cable or Air-Control Flush Valve   Uses steel cable or air pressure to transmit the flushing signal, opening the seal to let water flow into the toilet bowl. It’s flexible in installation, suitable for both top and side push buttons, making it a common flush valve for push button toilet systems.   5. Common Sizes and Compatibility   Sizes: Flush valves usually come in 1.5 inch, 2 inch, or 3 inch sizes. You can measure the tank outlet hole to confirm.   Base types: One-piece toilets use a flush valve one piece toilet base fixed with steel hooks. Two-piece toilets use a nut-fixed base.   Button sizes: Most tanks have push button openings of 38mm, 48mm, or 58mm. Always measure your tank lid hole before buying.   6. Common Problems and Solutions   Leaking – usually caused by an aged seal ring or a warped flapper. Replacement is the best fix.   Weak flushing – may happen if the tank water level is too low or if the valve is stuck. Check both the fill valve and flush valve.   Replacement advice – always choose a valve that matches your toilet’s size and installation type. The best toilet flush valve replacement kit usually includes seals, gaskets, and all parts needed for a simple DIY upgrade.   7. Key Points When Choosing a Toilet Flush Valve   1) Confirm size: Typically 2-inch or 3-inch.   2) Confirm base type: Flush valves for toilet in one-piece vs. two-piece designs require different bases.   3) Button style: Top push or side push, depending on tank structure.   4) Material: Durable engineering plastics like ABS or POM, combined with silicone gaskets for better sealing.   5) Water-saving design: Consider dual-flush or adjustable flush valves for maximum efficiency.   8. Conclusion   A stable and durable toilet flush valve not only provides a better flushing experience but also helps families save water. Regular inspection and timely replacement with the best toilet flush valve replacement kit can extend your toilet’s lifespan and keep your bathroom comfortable and efficient.

  • How to Remove Stuck Toilet Seat Plastic Bolts ?
    Aug 21, 2025
    Over time, toilets are used every day, and it’s normal for the seat to become loose or need replacing. But many people run into one frustrating issue—the stuck toilet seat bolt that just won’t turn. Don’t worry. With the right steps and tools, you can handle this problem easily.   Why Do Toilet Seat Plastic Bolts Get Stuck?   Moisture exposure: Bathrooms are humid places. After long-term contact with water, plastic bolts and nuts can age or deform, leaving the toilet seat bolt stuck. Dirt buildup: Dust, stains, and leftover cleaners can collect around the toilet seat nut and bolt, increasing friction and making removal difficult. Screwing too tight: If bolts were screwed on too tight during installation, they can lock into place and cause problems later when you attempt toilet seat bolt removal   Tools You’ll Need   Adjustable wrench or pliers Flathead screwdriver Lubricant (such as WD-40) Small hacksaw or rotary tool (for severe cases) Gloves and safety glasses   Methods to Remove a Stuck Plastic Bolt   Apply Lubricant Spray a small amount of lubricant around the nut and bolt area. Let it sit for a few minutes so it can seep in and loosen the grip. Loosen with Tools From underneath the toilet, insert a screwdriver into the bolt slot to hold it steady. At the same time, use a wrench to slowly turn the nut counterclockwise. If space is tight, you can also grip the nut with pliers while using the screwdriver to twist the bolt upward. Cutting Method If the bolt is too old or can’t be turned at all, carefully cut it off with a hacksaw or rotary tool. Be very cautious to avoid scratching or damaging the porcelain surface.   Tips for Installing New Bolts   When replacing toilet seat bolts, choose a high-quality toilet seat bolt kit with stainless steel or brass bolts. These are durable, rust-resistant, and easier to remove later. Do not screw too tight when installing—just make sure they’re secure. This will make future maintenance and toilet seat bolt removal much easier. Check and clean the bolts regularly to prevent dirt and moisture from locking them up again.   Final Thoughts   A stuck toilet seat bolt is a common bathroom issue. With the right tools and a little patience, most people can handle it at home. But if the bolts are extremely stubborn, the safest option is to call a professional plumber to avoid damaging your toilet.

  • How Do Toilet Fill Valves Work ?
    Aug 12, 2025
      When we open the lid of a toilet tank, we usually see two obvious plastic components — one is the fill valve, and the other is the flush valve. In this blog, we’ll focus on how a toilet fill valve works. Its main job is to control water entering the tank and stopping it at the right time, ensuring that after each flush, the tank refills quickly and steadily to the set water level.   Basic Functions of a Toilet Fill Valve   The core functions of a fill valve are: Open quickly after flushing to let fresh water enter the tank. Automatically shut off when the water level reaches the set height to prevent overflow. Keep each refill consistent to save water.   Common Toilet Fill Valve Types   Float Ball Toilet Fill Valve – Uses a lever connected to a float ball. The float moves up and down with the water level to control the valve. It takes up more space but works better in low water pressure environments. Double-Float Toilet Fill Valve – Uses two floats to trigger the shut-off. The design is more compact and space-saving. Pressure Toilet Fill Valve – Senses water pressure changes inside the tank to control shut-off. This type is the smallest in size and fits tight spaces.   Toilet Fill Valve Working Principle   1. Float Ball Toilet Fill Valve   Flushing Stage: Pressing the flush button opens the flush valve, and water from the tank rushes into the toilet bowl. Refill Start: As the water level drops, the float ball drops, moving the lever and opening the inlet. Water Level Rising: Water flows into the tank, and the float ball gradually rises. The inlet starts to close slowly, so the refill speed decreases. Refill Stop: When the water reaches the set level, the float ball pushes the shut-off mechanism to fully close the inlet.   2. Double-Float Toilet Fill Valve   Flushing Stage: Same as above. Refill Start: As the water level drops, the outer float drops and opens the inlet. Water Level Rising: Unlike the float ball design, the double-float system keeps the maximum refill speed until the water reaches the height of the outer float, resulting in the shortest refill time. Refill Stop: Once the water reaches the outer float height, the inner float instantly rises and triggers the shut-off mechanism.   3. Pressure Toilet Fill Valve   Flushing Stage: Same as above. Refill Start: As the water level drops, the internal water pressure also decreases. The valve senses this pressure change and opens the inlet. Water Level Rising: Water enters the tank, the pressure gradually increases, and the refill speed slows down (similar to the float ball type). However, because it relies on pressure as the trigger, the shut-off water level may vary slightly each time. Refill Stop: When the water reaches the set level, the internal spring mechanism pushes the seal to close the inlet.   Anti Siphon Feature   A high-quality anti siphon toilet fill valve prevents water from the toilet tank from flowing back into the household water supply, protecting drinking water from contamination.     Regularly checking and maintaining your toilet fill valve ensures smooth flushing and saves water. Choosing the right toilet fill valve type can improve refill efficiency, extend the life of your toilet, and reduce the need for repairs.

  • How To Clean Basin Overflow ?
    Aug 04, 2025
      1. Why Should You Clean the Basin Overflow Regularly?   The basin overflow is typically located near the front edge of the sink or just below the faucet. It serves as a backup drainage channel—when the water level in the basin gets too high, it allows excess water to flow into the drainage system, preventing overflow onto your bathroom floor. However, since the overflow for basin is constantly exposed to moisture and lacks proper ventilation, it's prone to accumulating dirty water, soap scum, and bacteria. If not cleaned regularly, this hidden area can pose hygiene risks and cause unpleasant odors in your bathroom.   2. Step-by-Step Guide to Cleaning the Basin Overflow   Step 1: Initial Rinse Pour a kettle of hot water or fresh tap water into the overflow opening. This helps soften grime and flush out loose surface debris.   Step 2: Surface Scrubbing Dip an old toothbrush in a cleaning agent and scrub around the opening of the basin overflow cover, removing visible soap residue, limescale, and dirt buildup.   Step 3: Deep Cleaning Mix approximately 50ml of white vinegar with a teaspoon of baking soda and pour it into the overflow hole. Let it sit for 10 minutes. You may notice bubbling or fizzing—that's normal and indicates the solution is working to dissolve internal gunk.   Step 4: Internal Flushing Use a syringe or soft hose to inject warm water deep into the overflow channel. This will rinse out any remaining dirt or smell. Repeat the process a few times until the sink basin overflow ring is clean and odor-free.   3. Preventive Tips for Daily Maintenance   To keep your basin overflow clean for longer, consider the following tips:   Lightly brush the overflow opening with a toothbrush once a month   Pour in vinegar or baking soda water regularly to prevent odor buildup   Avoid letting foam, hair, or toothpaste debris enter the overflow while washing your face or hair   Consider installing a wash basin overflow cover or basin overflow cap—these not only block unwanted debris from entering but also serve as a stylish accessory to enhance the look of your sink   4. Final Thoughts   We use wash basins every day to rinse towels, wash hands, and more. While the basin overflow cover may seem insignificant, neglecting its maintenance can lead to hygiene issues that affect both your sink and your skin health. A little regular cleaning goes a long way toward keeping your bathroom fresh, clean, and safe.

  • What Size Flapper for Toilet?
    Jul 25, 2025
      What Is a Toilet Flapper?   A toilet flapper is the flexible rubber valve that sits on top of the flush valve opening in your toilet tank. It’s connected to the flush handle or button by a chain. When you flush, the flapper lifts, allowing water to rush from the tank into the bowl. After the flush, it drops back into place to seal the valve and let the tank refill.   If the flapper doesn’t seal tightly — which is a common issue referred to as a toilet flapper valve not sealing — water will continue to leak into the bowl, wasting water and increasing your utility bill.   Why Flapper Size Matters   Getting the correct size flapper is more important than most people realize. An oversized flapper may not sit flush with the flush valve opening, causing it to leak. On the other hand, a flapper that’s too small might not cover the valve entirely, or may shift out of place. Either case leads to a poor seal and can cause problems like inconsistent flushing or continuous running water.   In short, the wrong size flapper can lead to:   Weak or partial flushes   Higher water bills   A constantly refilling tank   Toilet flapper valve not sealing   Common Toilet Flapper Sizes   There are three main categories when it comes to flapper sizes:   1. 2-Inch Toilet Flapper   This is the most common size used in standard toilets, especially older or traditional models. If you're unsure, there's a good chance your toilet uses a 2-inch flapper.   2. 3-Inch Toilet Flapper   Larger flush valves (often found in newer high-efficiency toilets) use 3-inch flappers. These allow for a more powerful flush using less water, which makes them popular in brands like Kohler and TOTO.   3. Specialty or Custom Flappers   Some toilets use uniquely shaped or branded flush valve systems that require a specific flapper size or structure — such as flappers with wings, floats, or hard plastic designs.   How to Tell What Size Flapper You Need   There are several ways to determine the right flapper size for your toilet:   Method 1: Measure the Flush Valve Opening   Use a ruler or caliper to measure the inside diameter of the flush valve seat:   Around 2 inches (50mm) → You need a 2-inch flapper   Around 3 inches (76mm) → You need a 3-inch flapper     Method 2: Check the Manufacturer’s Label or Manual   Look inside the toilet tank lid or on the brand’s website. Most manufacturers will list the flush valve size, especially if it’s a selling point like “3-inch flush valve for better performance.”   Method 3: Visual Comparison   If you don’t have tools handy, use this general guide:   If the flush valve opening looks about the size of a golf ball, it’s likely a 2-inch flush valve   If it’s closer to the size of a tennis ball, it’s likely a 3-inch flush valve

  • How Do Push Button Toilets Work?
    Jul 18, 2025
      Push button toilets are a modern upgrade to the traditional lever-flush models. They're sleek, easy to use, and help save water — which makes them super popular in today’s bathrooms. But have you ever wondered what actually happens when you press that button? Let’s take a closer look at how push button toilets work, and what’s going on behind the scenes.   1. What Is a Push Button Toilet?   A push button toilet is exactly what it sounds like — instead of pulling a handle, you press a button to flush. The button is usually located on the top or side of the tank, and it connects to an internal flush valve that releases water when activated.   How Is It Different from Traditional Handle Toilets?   Looks more modern and neat   Easier to use — just a simple press   Often comes with dual flush buttons to save water   Works great with concealed or one-piece toilet designs   2. Common Types of Push Button Flush Mechanisms   Not all push buttons work the same way. There are actually four common types of mechanisms that connect the button to the flush valve:   Lever-Driven   When you press the button, it lifts a lever inside the tank. That lever is attached to a chain, which pulls open the flapper (or flush seal) and lets water rush into the bowl.   Rod-Press   This type uses a rod directly under the button. When pressed, the rod pushes down on the flush valve’s top button, triggering the flush.     Cable-Control (Wire Pull)   This one uses a thin wire inside a plastic tube. Pressing the button pulls the cable, which opens the flush valve. It's flexible and great for side-mounted or custom installations.     Air-Driven (Pneumatic)   Here, the button is connected to the flush valve via an air tube. When you press the button, it sends air pressure through the tube, which then opens the valve. This setup is often used in concealed tank toilets.     3. How the Flushing Process Works   Even though there are different mechanisms, the basic idea is the same. When you press the button, you're triggering the flush valve to release water from the tank into the bowl. Here's how each one works:   Lever-Driven: Button lifts the lever → lever pulls the chain → chain lifts the flapper → water rushes out   Rod-Press: Button presses down → rod hits the flush valve button → valve opens   Cable-Control: Button pulls the cable → flush valve opens   Air-Driven: Button pushes air → air activates flush valve → water flows out   After flushing, the valve closes, and the fill valve refills the tank, getting ready for the next flush.

  • How to flush a toilet when the handle is broken ?
    Jul 08, 2025
      The toilet is one of the most frequently used fixtures in any bathroom. After long-term use, it’s not uncommon to encounter broken components—like a flush handle that no longer works because the internal mechanism has snapped. While this might seem frustrating, there’s no need to panic. With a few simple tricks, you can still flush your toilet without the handle and keep your bathroom clean and functional.   Here are some quick and practical ways to flush your toilet when the handle is broken.   Step 1: Understand How the Toilet Handle Works   The flush handle might look like a small part, but it’s actually the trigger of the entire toilet flushing system. It’s connected to a lift rod or chain inside the tank. When you press the handle, it pulls up the toilet flush valve flap or canister, allowing water to rush from the tank into the bowl to flush waste away. Understanding this mechanism will help you operate it manually when the handle stops working.   Step 2: Three Manual Flushing Methods You Can Try   1. Pull the Chain Inside the Toilet Tank   First, remove the toilet tank lid. You’ll see a chain connecting the handle to the flush valve—this chain might be plastic or stainless steel. Gently pull the chain upward with your hand. This action opens the flush valve and lets the water flow into the bowl, effectively flushing the toilet. Once flushing is complete, simply release the chain and let it drop back into place. This is the most straightforward temporary solution. Just be careful not to yank too hard, as excessive force can damage the flush valve or break the chain.   2. Lift the Flapper or Canister Directly   If the handle stopped working because the chain snapped (which often happens with plastic chains), then method one may not work. In that case, you can manually lift the toilet flapper or canister directly by hand. Lifting it fully will open the flush valve and allow water to exit the tank. Once the flush is complete, gently lower the flapper back into place. Be careful not to let the broken chain fall into the drain hole—this could prevent the flapper from sealing properly and cause the toilet to leak.   3. Use a Bucket to Flush the Toilet   If you don’t want to mess with the tank at all, here’s a traditional approach: flush with a bucket of water. Fill a bucket with about 6 liters (or 1.5 gallons) of water—that’s approximately the full flush volume of most toilets. Quickly pour the water into the bowl from a height, aiming for the drain hole. This creates a forceful rush of water that mimics the effect of a regular flush and clears the waste. Pour quickly but carefully to avoid splashing dirty water, and make sure to pour directly into the center of the bowl for the best results.   Step 3: What to Do After the Temporary Fix   While the above methods are great for emergencies, they’re not permanent solutions. Manually opening the tank every time is inconvenient and can potentially damage internal components. You should replace the toilet handle as soon as possible. Many universal toilet tank levers are available online—Amazon has a wide selection to choose from. If you're not confident about installing one yourself, consider hiring a plumber. You can also check out our website, where we provide video tutorials on how to install different types of toilet flush handles.   Final Thoughts: Don’t Panic When the Handle Breaks   A broken toilet handle isn’t the end of the world. Once you know the right tricks, you can flush your toilet just fine and keep everything hygienic until a repair is done. Regularly inspect your toilet’s internal components to catch small issues before they turn into big problems.

  • Does a new toilet include flush valve ?
    Jul 03, 2025
      When buying a new toilet, many consumers ask the same question: Does the toilet come with a flush valve included? Understanding this can help you avoid buying unnecessary parts and ensure your toilet is ready to install and use right out of the box.   What Is a Toilet Flush Valve?   A toilet flush valve is a critical component inside the toilet tank. It controls the flow of water from the tank into the bowl during flushing. A typical flush valve for toilet includes an overflow tube, a sealing component (like a flapper or sealing), and a connection to a flush button or handle.   Does a New Toilet Come with a Flush Valve?   Yes. Whether it's a one-piece toilet, a two-piece toilet, or a toilet with a concealed tank, manufacturers usually include a toilet flush valve as a standard part of the package. It’s part of the toilet’s certified structure and function, and most brands ship their toilets as complete sets with all internal components pre-installed or included.   This ensures the toilet can be installed and used without the buyer needing to purchase extra parts like a toilet flush valve replacement.   When Do You Need to Buy a Flush Valve Separately?   In some cases, you may still need to purchase a flush valve for toilet separately:   You intentionally buy a toilet that includes only the ceramic components, with no internal tank fittings;   You want to upgrade or customize the system, for example, changing to a dual flush toilet;   The flush valve in your old toilet is broken and needs replacing;   You’re building a custom setup using a non-standard water tank.   How to Know If a Toilet Includes a Flush Valve?   Check the product description or manual – Most listings will specify whether internal tank parts are included;   Ask the seller or manufacturer – This is especially important when buying from online or B2B platforms;   Look at product images or unboxing videos – Some brands show the inside of the tank to indicate what's included.   Conclusion   There’s no one-size-fits-all answer to whether a new toilet includes a flush valve. It depends on the toilet type and how it’s being sold. To avoid any installation surprises, always double-check what's included in the box before making a purchase. If you’re still unsure about choosing the right toilet flush valve, feel free to reach out to a professional supplier for guidance.

  • What Is The Best Toilet Fill Valve?
    Jun 26, 2025
      Choosing the right toilet fill valve isn’t just about stopping and starting water flow—it’s about achieving long-term reliability, efficient flushing, and protecting water resources. Below are six key standards for determining what makes the best toilet fill valve:   1. Suitable Water Pressure Range   A high-quality fill valve should operate well under both high and low water pressure. It must be able to stop water flow properly at high pressure and allow steady refill at low pressure. For example, our dual float cup fill valve is compatible with pressure ranges from 0.03 MPa to 1.5 MPa, making it ideal for both domestic and international markets.   2. Refill Speed and Shut-off Accuracy   A top-performing fill valve delivers stable refill speed before the float rises, and it shuts off within ±5mm of the working water level after every flush. This ensures a consistent flushing volume and avoids unnecessary water waste—key features of a truly efficient toilet tank fill valve.   3. Anti-Siphon Protection   Look for the letters “CL” marked on the valve body—this indicates the presence of a built-in anti-siphon system. A fill valve with proper anti-siphon function prevents contaminated water from flowing back into the clean water supply in case of negative pressure.   4. Material Quality   The best toilet fill valves are typically made from POM (polyoxymethylene) material, known for its high resistance to pressure and corrosion. This helps prevent cracking and ensures long-term durability, especially in areas with hard water or fluctuating pressure conditions.   5. Certifications and Compliance   Reliable fill valves come with certifications like ICCES, CE, WRAS, and WaterMark, indicating that the product meets safety and quality standards in different countries. Certifications are a strong guarantee of performance and durability.   6. Market Feedback   At the end of the day, customer feedback speaks volumes. A fill valve with excellent reviews, high reorder rates, and strong performance in both retail and engineering projects is what you should be looking for. A proven track record in the market is a solid indicator of a universal toilet fill valve replacement worth investing in.
