Adjusting the Flapper Chain

The first thing you should do is to adjust the flapper chain. If you want to do this, remove the lid from your toilet tank and note the parts. After that, grab the lid from both sides and gently lift it upward. Set it down on a piece of cardboard to avoid getting your floor wet. Now, take the note of the parts in your tank: the flushing handle should be connected to a long metal or plastic handle arm that connects to the flapper chain.

Another thing to do is take the chain off of the handle arm. Reach into the tank and remove the chain link that connects the handle to the flapper. There should be a small opening in the link that lets you remove it.

Hook a paperclip to the handle arm. The next thing is tart by opening up the paper clip until it’s straight. Now, bend the clip into a circle with a small opening in it. Afterward, hook the circle into the end of the handle arm where you removed the chain.

Now, connect the chain to the paper clip. Attach a link on the chain to the paper clip which should now be a circle shape-by inserting it into the open end. The next thing is, squeeze the sides of the paperclip to the space and tighten it.

Now, Flush the toilet and check the chain tightness. Press down on the toilet handle and make sure that the chain is tight enough. The chain should bring the flapper high enough to stay open while the toilet flushes. But if it doesn’t, continue adjusting the paperclip location until the chain tightness is ideal.

Replace Your Toilet Flapper Valve

To replace your toilet flapper valve, you have to follow the following process..

Drain as much water from the tank as possible. Remove the tank lid and turn the shut off valve clockwise to turn it off. Now, press the toilet handle down until there’s  no water inside the tank.

Take out any water left in the tank. Get a towel and sponge and wipe up the rest of the water in the tank. If there’s still water inside the tank, squeeze out your towel into a bucket and continue wiping it until the water drained out.

Remove the water supple hose. Loosen the nuts located on the base of the water supply valve which is what the flapper is connected to. Do this by using an adjustable crescent wrench. Afterward, pull out the water supply hose and set it aside.

Remove the old flapper valve. Start by removing the chain from the old flapper. After that, take the flapper off the flush valve, which is the piece the supply tube was connected to. And if you want to put a new chain, remove the old one from the lever arm. I mean the long piece that extends from the toilet handle.

Connect The New Flapper Valve

Attach the new flapper to the flush valve. Afterward, connect the chain to the top of and then connect the remaining end to the handle arm. However, before attaching a new flapper, smooth the rough edges around the lip of the flapper valve. This is located underneath the flapper with an emery cloth. This will definitely help it create a watertight seal.

Reattack the water supply hose and turn the water back on. Attach the water supply hose to the flush valve, which is where the new flapper should be attached. Afterward, turn your water supply back on by turning it counterclockwise and wait for the toilet to fill up. Having done that, replace the lid once everything I working as it should be.

Repairing A Flapper Or Replacing It

Flappers cost less than $10 on average, so if your toilet flapper closes too fast, it’s usually better to replace the flapper than it is to try and repair it. However, if the flapper isn’t that old, or you don’t have time to take it to the store,  just as I said earlier, you might be able to fix the problem by cleaning the flapper and flush valve.

Rub the toilet flapper down with scouring powder and a sponge to remove all the mold and scale that may have collected on it. Then do the same to the rim of the flush valve. It may help to run a bead of silicone caulk around the rim of the valve to make a better seal. If you do this, give the caulk a least eight hours to set before you set the flapper on it and fill the tank.

The Case Of The Phantom Flusher

If your toilet fills valve switches on all by itself in the middle of the night or anytime, you’ve got a phantom flush. The number one reason for the phantom flush is a leaking flapper. The problem may be that the flapper chain is one or two links too short and doesn’t allow the flapper to seat properly. But if your toilet is well used, the flapper may just be worn out.

Turn off the water and take the flapper off its mounting by disengaging its rubber ears from the overflow tube or sliding it up and off that rube after disengaging the flapper chain. Take it to the store to find a replacement. In most cases, an inexpensive universal flapper does the job.  Some flush valves require specific flappers, though, so you might have to consult with the clerk at the hardware store to make sure you get the right one.

Some flapper leaks are too slow to notice, but they still waste water. If you suspect you have a flapper leak, try this test: Pour some food coloring in the tank, and avoid using the toilet for several hours or overnight. The test is positive if the bowl water takes on the same hue as the tank water.

A Summary Of toilet flapper closes too fast.

  • Make sure the lift chain is not so long that it pinches between the flapper and the flush valve. If it is, water will leak down into the toilet bowl after the flush. Shorten the chain slightly so it doesn’t get pinched beneath the flapper.


  • Make sure the flapper is properly aligned so it seals correctly against the flush valve opening. You may be able to make small adjustments to the flapper that magically stop the leaking.


  • If the rubber of the flapper is old and cracked, it will be unable to seal the flow of water into the tank. In this case, you will need to replace the flapper.

In conclusion, open the tank and test the tension on the flapper chain by pulling up on the center. You shouldn’t be able to pull it up more than about ½ inch before the flapper starts to rise. Alternatively, push down on the flush handle to test the tension. The flapper should start to rise before the handle is halfway down.
