How to Replace a Toilet Flapper
How to Replace a Toilet Flapper. Generally, when a toilet tank begins to intermittently fill with water (the aftermath of flushing) when no one is using it, this is a sign that the toilet flapper needs replacing. Modern toilet flappers are made of soft rubber and can last many years. However, using harsh chemicals to clean and disinfect a toilet and tank can rapidly deteriorate and or harden a rubber flapper, resulting in a flapper that no longer holds a seal. In the following simple solution I cover the process of replacing a toilet flapper.
Changing a Toilet Flapper:
- First, shut off the water supply to the toilet:
- Next, remove the toilet tank lid and flush the toilet numerous times until there is no longer water remaining in the tank
- Now, unlatch the clip that attaches the flapper chain to the handle lever:
- Next, from inside the toilet tank, gently pull up on the flapper arms to release the old flapper from it's posts:
- New Flapper: Remove the clip from it's chain and place the new flapper into position over the posts within the toilet tank:
- With the new toilet flapper seated, lift the chain up to the handle lever. Leaving two to three links of slack in the chain, reattach the clip to the chain and then to the handle lever. There should be no tension on the chain when the flapper is in the seated position:
- Turn on the water. Once the toilet tank has stopped filling with water, flush the toilet to * ensure that the toilet is flushing and filling properly.
*(Optional) If your new flapper is an adjustable water saving toilet flapper, you can adjust the new flapper to allow more or less flushing volume:
