If your toilet seems to be running constantly you are probably wondering how to replace a toilet flapper. Replacing a toilet flapper is a relatively cheap and easy fix to the problem of a constantly running toilet.

However,  sometimes even the “simplest” of do-it-yourself projects can take on a life of their own.

The first thing that you will need to do is purchase the replacement part from a local hardware store. There are many different brands to choose from but the last time that I replaced a toilet flapper the American Standard toilet flapper should fit the bill.

Once you have your replacement parts you will need to either shut off the water supply to the toilet or secure the fill valve in the closed position. This will prevent you from wasting water and make it easier for you to work in the back of the toilet tank.

Keep in mind that every toilet tank is different, as is every toilet flapper. You might find it difficult to work on an undersized toilet. Changing a toilet flapper varies from one toilet to another. However, every homeowner should learn how to replace a toilet flapper.

However, if you do not understand the basic mechanics of how a toilet works or if you have a toilet tank that is prohibitively small, it may be best to call a plumber to get the job finished quickly and professionally.
