How to Fix Toilet Flapper – Simple DIY Guide

Are you struggling with toilet leaks? I did! For close to three months, my toilet couldn’t stop running. I thought it was normal and that sometimes a toilet would run. I was wrong. Turns out; my toilet was broken, and the high water bill I settled would have been saved had I paid attention to expert toilet reviews.

How to Fix Toilet Flapper

After long research I learned a lot. There are many causes of a leaking toilet. It might be a broken flapper, poorly set float, or damaged bullock. The good news is, with the right tips, you can easily fix most of the toilet leak problems alone. In this post, I will show you how to fix the most common toilet leak problem – a damaged flapper.

To start off, you should identify the toilet flapper. Open up the cover of your toilet tank. When you do, you will see a set of flushing components.

The Float Options

The float component comprises the float ball and a bar. It also has an overflow pipe on the side. This set is easily used to adjust the level of water in your toilet’s water tank.

The Toilet Flapper

The remaining component comes with a metallic rod/ hard plastic rod that stretches from the toilet handle. At the end of the rod are two or more holes. One of the holes suspends a metallic chain link or road.

The chain link then attaches to a hard plastic rubber at the bottom of the tank. When you pull your toilet handle down, the chain comes up and lifts the plastic cover at the bottom of the toilet tank subsequently revealing a hole through which the water rushes out to flash off the waste from the bowl and into the drain.

This rubber cover is called the flapper. Due to a high rate of wear and tear, poor fixing, or short chain links the flapper might fail to work properly. It will let water through and cause your toilet to run.

Fixing the Flapper

Fixing the flapper problem is very easy. You can either replace the flapper or shorten the chain link. To replace the flapper, here is what you must do.

Step 1:  Shut off the inlet water flow system at the main shut off valve. Then flush off your water tank by pulling your toilet handle downwards and holding it for a while. This same action should pull up the flapper.

Step 2:  If the leak is caused by a short chain that doesn’t provide a proper seal, you can unhook the chain at the top of the flushing rod and move it one step back to the previous hole. The hole is at the top of the flushing bar. This action will lengthen the chain to give you a proper seal.

Step 3:  If the flapper is damaged, you can buy a new flapper. This can be found in the local hardware shop. Simply detach the flapper from the chain link. Then take it with you to the hardware. Get a new flapper and come back to hook it at the end of the chain link. Once done you should test your flapper by restoring the flow and flushing your toilet.


Your toilet should stop running now. Make sure your flapper provides the perfect seal. For quick help, you should read through Our Recommended Toilet Review and get the best toilet with no flapper problems.
