Is your toilet running? The most common cause of a leaky toilet is a toilet flapper valve that isn’t quite seating properly at the bottom of the tank. Replacing a toilet flapper valve is a relatively simple fix that could save you a pretty penny on your water bill.
First, it’s worth noting that not all flapper designs are the same. Before buying a replacement flapper, be sure to take the old one to the store with you so you can be sure the new one is a fit.
Once you have a compatible flapper ready to install, be sure to first shut off the water supply valve to the toilet tank. Remove the lid from the tank, and flush the toilet to remove as much water as possible.
You’ll note that the chain attached to the flush lever is the mechanism that lifts the toilet flapper, releasing water into the bowl. Disconnect this chain from the toilet lever. Then, pull the flapper off of the mounting pegs on either side of the overflow tube.
It’s important to be sure to wipe off the valve seat at the bottom of the tank to ensure a clean seal between the area and the new flapper valve, once installed. Next, go ahead and install the new flapper valve where the old one sat. Connect the chain back to both the flapper and the flush lever, then test the amount of slack you’ll need by pushing down on the flush lever a few times, watching to make sure the flapper comes up and down appropriately.
Lastly, turn the water supply back on and let the toilet tank re-fill with water. The new flapper valve should form a tight seal, fixing the leaky toilet that once was.
