Does the Flapper Need to be Replaced?
Let’s assume that your toilet continues to run after being flushed. And you’ve already tried adjusting the flapper.
The next step is to determine if you have a worn or cracked flapper. Thankfully, this is super easy. All you need to do is look at the bottom of the flapper.
The flapper itself is usually made of rubber but might be made of plastic. In either case, the underside should be completely smooth. There should be no indication of wear, rips, or cracks. If you see any of these, then replacing a toilet flapper is the right move.
Here’s What You Need
Replacing a toilet flapper requires very little. The materials and tools required include:
- New replacement toilet flapper
- Slip-joint pliers (possibly)
- Scrubbing pad
Assuming that you already have your replacement flapper and these tools, you’ll only need about 20-30 minutes to do this job.
Replacing a Toilet Flapper in 6 Steps
If your toilet still runs after adjusting your toilet stopper (the flapper), it’s probably worn out or cracked. The good news is that replacing a toilet flapper can be done quickly with these steps.
- Begin by turning off the water supply valve. It is usually a round handle that can be found under the toilet tank, against the wall on the left side.
- Flush the toilet to empty the tank and sponge dry the tank.
- Unscrew the old flapper from the lift wire. If necessary, grip the top loop in the lift wire with slip-joint pliers to keep the lift wire from turning.
- Take the old flapper to a hardware store or plumbing supply house and purchase a replacement. Screw the new flapper onto the lift wire.
- Pull up the new toilet flapper and clean the inside of the flush valve outlet by scouring it with a scrubbing pad. By doing this, you’ll ensure that the flapper fits snugly onto the flush valve seat and creates a watertight seal.
- Drop the flapper into position and turn on the water supply valve under the toilet tank.
That’s all there is to it. Now all you need to do is flush the toilet to celebrate your handiwork.
