toilet flapper and chain diagram

If you have ever removed the lid from the tank of your toilet, odds are, you’ve noticed a flap connected to a chain. This is called the “flapper.” The flapper and the chain that is connected to it is part of the flushing process. When you flush the handle, the chain is pulled by a lever and lifts the flapper. When the flapper is lifted, it empties the water in the tank and refills the water in the toilet.

The chain sits in the water 24/7, except for the few moments when the water in the tank is drained. This means, the chain is eventually going to rust, break and then need to be replaced. If your toilet won’t flush – check the chain, because it might be broken. Other signs the flapper and chain need to be replaced is if the water in the toilet bowl is discolored or there are black flakes in the water. This is a sign that the flapper is deteriorating and needs to be replaced. Another sign your flapper and chain needs to be replaced is if the toilet is constantly running or the system keeps turning on and off.

The flapper and chain are a unit – if one needs to be replaced, so should the other. Even if it appears to be intact, they should both be replaced at the same time.

Before you even take the lid off the tank, turn off the water – the shut off valve is located behind the tank of the toilet. Next, you want to flush the water out of your toilet so the tank is empty. Remove the chain clip from the lever and unclip the flapper at each end.

There are many different sizes and types of flappers, it is important that you get the correct size flapper because this will influence how much water is used per flush. If your flapper has a timer ball connected to it or a meter timer connected at the bottom, be sure to get one exactly like it. To make sure you get the same size flapper, take the flapper with you to your local hardware store.

Once you have the correct flapper, replace the flapper first and connect the chain clip to the lever. Test the lever to make sure the chain is adjusted tight enough to lift the flapper. Just like that, you have successfully replaced the flapper and chain. Turn the toilet water valve back on, ensure the tank is successfully filling back up with water – once it is completely full, flush the toilet to see that it is all working properly.

Should you have any problems or replacing the flapper and chain did not fix the problem, call Gillece to have a licensed and insured plumber solve the issue for you.
