How To Replace A Fill Valve In A Toilet Tank: A Step-by-step Guide (youtube Tutorial)

If your toilet is constantly running or not filling up properly, it’s likely a problem with the fill valve. Replacing a fill valve is a relatively simple task that can be completed in just a few minutes. In this comprehensive guide, we’ll provide step-by-step instructions on how to replace a fill valve in a toilet tank, accompanied by a helpful YouTube video for visual guidance.

Tools and Materials You’ll Need:

• New fill valve
• Adjustable wrench
• Screwdriver
• Pliers (optional)

Step-by-Step Guide:

1. Turn Off the Water Supply:
Locate the water supply valve behind the toilet and turn it clockwise to shut off the water.

2. Flush the Toilet:
Flush the toilet to empty the tank and bowl.

3. Disconnect the Water Supply Line:
Use an adjustable wrench to loosen the nut connecting the water supply line to the fill valve.

4. Remove the Old Fill Valve:
Unscrew the locknut that holds the fill valve in place. Lift the old fill valve straight up and out of the tank.

5. Install the New Fill Valve:
Align the new fill valve with the holes in the tank and insert it into place. Tighten the locknut by hand until it’s snug.

6. Reconnect the Water Supply Line:
Thread the water supply line onto the fill valve and tighten the nut with an adjustable wrench.

7. Adjust the Water Level:
The fill valve has an adjustable float that determines the water level in the tank. Adjust the float by bending the arm up or down until the water level is approximately 1 inch below the top of the overflow tube.

8. Test the Fill Valve:
Turn on the water supply and flush the toilet to test the new fill valve. Make sure the tank fills up properly and stops at the desired water level.
