'<br>The flapper valve is one of those valves that every homeowner should have in their home. It's a safety device that prevents the water in the toilet from spilling onto the floor. When you press the handle to release the water, the flapper valve rises and lets the water in the tank push everything out at the same time. This means that all the liquid inside the tank is pushed out at once, leaving nothing in behind. However, there are different types of flapper valve, and some have features that some people might not need or want. Here are some of them:<br><br><br>The most common type of flapper valve is the inline float mechanism. This is where the liquid in the tank is dropped into the tank, and it pushes everything up, including the flapper, until the valve opens. The inline type of valve works great for smaller tanks, and it can be difficult to find in larger tanks.

You can get the inline type with a smaller drop tube, but these tend to break easier than the larger tubes, and they don't do as good of a job.<br><br><br>Another common type of flapper valve is the chain-drive flapper valve. With this type, a chain is attached to the flapper and it has two holes on either side. When the flapper is open, this chain drags along the chain and pushes the flapper valve up and shuts it off when the chain is removed. These are popular with public toilets that don't have a shutoff, since the chain can catch all the liquid inside the toilet if the flapper is left open.<br><br><br>Another type of flapper valve is the overflow tube flapper. This is also a very effective flapper, but it doesn't have a great leak detection system. Because the flapper has a very limited amount of lift, it is important that there be a very good seal between the flapper and the overflow tube to keep the flow of sewage going smoothly. The overflow tube should be a long straight pipe, with a hole in it at the top. Some systems use a safety relief valve in case the flapper gets stuck up, but this can be a real hassle in maintenance and cleaning, so most overflow tube flappers are not replaced unless absolutely necessary.<br><br><br>Flapper seals can be replaced, but sometimes a re-seal may be needed. If your flapper valve has a chain that runs from the middle of the trap through the end of the trap, then when the chain is removed, the flapper valve should still be in good working order. The easiest way to replace a flapper is to lift out the old flapper valve, find the old seal, and replace it with the new one. In some systems, you can just remove the chain and unhook it from its own end. It is always important to match the new seal to the appropriate flapper chain, as different types of chains may have different letter markings on the label.<br><br><br>To change the flapper on a water source toilet, you must remove the drain plug from the toilet tank. Then, you need to locate the shutoff valve for the main water supply. You can either turn the handle clockwise or counterclockwise to open and close the flapper valve. Next, turn the water supply to the correct position and hook the flapper chain to the corresponding spool on the toilet tank. Turn the shutoff valve to close the flapper, which disconnects the water supply valve from the toilet tank.<br>'
