How to Fix a Toilet Fill Valve

DIY Guide: Fixing Your Toilet Fill Valve in Simple Steps

If your toilet is constantly running, there's a good chance that the fill valve is the culprit. Luckily, fixing a toilet fill valve is a relatively simple process that can be done in just a few steps. Here's how to fix a toilet fill valve:

Step 1: Turn off the water supply
Before you begin working on your toilet, you'll need to turn off the water supply. Look for the shut-off valve near the base of the toilet and turn it clockwise to shut off the water.

Step 2: Drain the tank
Flush the toilet to drain as much water as possible from the tank. If the water level is still too high, use a cup or bucket to scoop out the remaining water.

Step 3: Remove the old fill valve
Locate the fill valve inside the tank. It should be attached to the bottom of the tank with a nut and washer. Use pliers or a wrench to loosen and remove the nut, then lift the old fill valve out of the tank.

Step 4: Install the new fill valve
Insert the new fill valve into the hole in the bottom of the tank, making sure it's centered and level. Secure the valve in place with the nut and washer, and tighten it with pliers or a wrench.

Step 5: Adjust the height of the fill valve
Most fill valves have an adjustable height to accommodate different tank sizes. Adjust the height of the valve so that it sits about an inch below the top of the overflow tube.

Step 6: Reconnect the water supply
Turn the water supply back on and let the tank fill with water. Check for any leaks around the fill valve and tighten the nut if necessary.

Step 7: Test the toilet
Flush the toilet a few times to make sure the fill valve is working properly. If the toilet still runs, adjust the height of the valve or check for any other issues.

With these simple steps, you can fix a toilet fill valve and put an end to that annoying running sound. If you're not comfortable tackling this task on your own, don't hesitate to call a professional plumber for help.
