• 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 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.
