How to Replace a Toilet Flapper in 6 Steps

How To Replace A Toilet Flapper

The toilet flapper is a tiny, hinged flap valve that lives within your toilet tank. This simple piece of plastic and soft rubber is small but mighty and has an important job to do. Connected by a chain hanging down from the flush handle lever, the flapper allows you to flush your toilet without giving it a second thought.

Toilet flappers can last up to four or five years, but eventually, the flapper will break down and need to be replaced. Fortunately, replacing the flapper is both easy and inexpensive, but it’s important it’s installed the right way so your toilet works as it should.

If you’re wondering how to replace your toilet flapper, our simple six-step guide will walk you through the process. Best of all, the only material you need is a new flapper, which costs just $5.

How to Replace a Toilet Flapper In 6 Steps

The following is a step-by-step guide on how to replace your toilet flapper:

Step 1. Turn off the water

Locate the shutoff valve and turn off the water to your toilet. The shutoff valve is typically located on the water supply line that leads to the toilet.

Once you locate the valve, turn the valve handle clockwise until it comes to a stop.

Step 2. Drain the tank

Once you’ve shut off the water, the next step is to drain the tank. You’ll want to drain the tank entirely by flushing the toilet.

Step 3. Remove the old flapper

Once the water is off and the tank is drained, it’s time to remove the old flapper. This is done by carefully disconnecting the flapper chain from the flush handle lever. Usually, there will be a tiny clip on the top end of the chain hooked into one of the holes on the handle lever. All you need to do is undo this clip and let the chain fall.

From here, slide the side ears of the old flapper off of the pegs.

Step 4. Grab your new flapper

If you haven’t already, you’ll need to have your new toilet flapper ready. There are lots of types of flappers available to homeowners, most of which range from $5 to $20. Any flapper will do, but it never hurts to read reviews online before making a purchase.

Once you have your new flapper, take notice of the design of both your flapper and toilet. How you install the flapper will depend on the flapper itself and your toilet’s design. Most toilets are designed to have the flapper installed on the red pegs located on the sides of the flush valve tubes. If your toilet is configured this way, simply cut off the ring on the back of the new flapper and discard it.

If your flush valve doesn’t have the side pegs, you will use the ring provided with the new flapper.

Step 5. Install the New flapper

To install the new flapper, put the flapper in place and hook each of the ears onto the pegs on the flush valve.

Once the ears are connected, connect the flapper chain onto the handle lever. From here, the chain length may need to be adjusted. Keep in mind that when the toilet handle is in the resting position, the chain should be relaxed.

This step is very important because if the chain is too tight, the flapper may not close completely. If the chain has too loose, it can prevent the flapper from forming a tight enough seal.

Step 6. Turn the water on

Once your new flapper is installed, turn the water back on at the shutoff valve.
