Fix Your Running Toilet In Just 5 Minutes – Here’s How To Change Your Fill Valve!

Is your toilet constantly running or refilling too slowly? The culprit could be a faulty fill valve. Changing a fill valve is a relatively simple plumbing task that can save you money and frustration. In this comprehensive guide, we’ll walk you through the steps on how to change fill valve on toilet.

What is a Fill Valve?

A fill valve is a device that controls the water flow into the toilet tank. When the water level drops below a certain point, the fill valve opens to refill the tank. A faulty fill valve can lead to a number of problems, including:

• Constantly running toilet
• Slow refilling toilet
• Overflowing toilet

Tools and Materials You’ll Need

Before you start, gather the following tools and materials:

• New fill valve
• Adjustable wrench
• Screwdriver
• Hacksaw (optional)
• Plumber’s putty (optional)

Step-by-Step Instructions

1. Turn Off the Water Supply

Locate the water supply valve behind the toilet and turn it off clockwise.

2. Flush the Toilet

Flush the toilet to empty the tank.

3. Disconnect the Water Supply Line

Use an adjustable wrench to disconnect the water supply line from the fill valve.

4. Remove the Old Fill Valve

Unscrew the nuts that hold the fill valve in place. The fill valve may be held in place by one or two nuts.

5. Install the New Fill Valve

a. Apply Plumber’s Putty (Optional): If the new fill valve has a rubber gasket, apply a bead of plumber’s putty around the base of the valve.

b. Insert the Fill Valve: Insert the new fill valve into the hole in the bottom of the tank.

c. Tighten the Nuts: Hand-tighten the nuts that hold the fill valve in place. Use an adjustable wrench to further tighten the nuts, but do not overtighten.

6. Reconnect the Water Supply Line

Use an adjustable wrench to reconnect the water supply line to the fill valve.

7. Adjust the Water Level

Once the water supply is turned back on, adjust the water level in the tank. The water level should be about 1 inch below the top of the overflow tube. The fill valve should have an adjustment screw that you can turn to adjust the water level.

Tips

• If the water supply line is too short, you may need to use a hacksaw to cut it to the desired length.
• If the fill valve is leaking, make sure that the nuts are tightened properly. You may also need to replace the rubber gasket.
• If you are having trouble removing the old fill valve, you may need to use a penetrating oil to loosen the nuts.

Troubleshooting

• Toilet is still running: The fill valve may be faulty. Try replacing the fill valve.
• Toilet is not refilling: The water supply line may be blocked. Check the water supply line for any kinks or blockages.
• Toilet is overflowing: The fill valve may be set too high. Adjust the water level in the tank.
