Do you know how to replace the toilet fill valve?

Replacing a toilet fill valve is not difficult, but it does require you to make some preparations and have the right tools. Before getting started, be sure that your water supply has been turned off. Inspect the old valve for any signs of leaks or corrosion before removing it from the toilet tank lid. The new fill valve should come with two O-rings which should be replaced whenever replacing the fill valve.

The new fill valve should be positioned so the threaded end is pointing up and out of the tank. This will allow it to seal properly when placed in position on top of the toilet tank lid.

What Do You Need?

To replace a toilet fill valve, you’ll need:

A wrench or adjustable pliers loosen the bolts attaching it to the toilet tank lid.
A bucket for water that might leak out from under the old fill valve and can’t be turned off (or just turn on a nearby faucet).
Replacement O-rings if needed. If your new fill valve doesn’t come with two, buy some now! You don’t want to have any leaks down there when done.

How to Choose A Best Toilet Fill Valve?

You need the best toilet fill valve to replace it with the old one. But what is the best way to buy the best one?

This will allow it to seal properly when placed in position on top of the toilet tank lid.

Step by Step Guide: How to Replace the Toilet Fill Valve?

So, now you have a new toilet fill valve. Okay, let’s go to replace it by following these steps:

Turn off the water supply at the shutoff valve behind the toilet tank. Remove old filler assembly by unscrewing bolts using an adjustable wrench or pliers. Inspect bolt threads in case they are corroded before installing new valves so as not to cause leaks. Place a bucket under the old valve if possible to catch any water that might leak out of it and can’t be turned off. Remove the old O-rings from both valves (the new one will come with two) so you don’t have leaks when done installing. Install new fill valve by screwing bolts in using an adjustable wrench or pliers until tight, then put on a new set of O-rings onto both valves; tighten them as well. Turn back on water supply at shutoff valve behind toilet tank and check for leaks around the base of filler assembly before replacing lid cover.
