DIY Plumbing Mastery: Step-by-Step Instructions on How to Replace the Fill Valve in Your Dual Flush Toilet

Replacing a fill valve in a dual flush toilet can be a daunting task, but it doesn’t have to be. With the right tools and a little patience, you can get the job done in no time. Here’s a step-by-step guide to help you through the process:

Tools You’ll Need:

• Adjustable wrench
• Screwdriver
• Pliers
• New fill valve

Step 1: Turn Off the Water Supply

The first step is to turn off the water supply to the toilet. Locate the shut-off valve behind the toilet and turn it clockwise until the water stops flowing.

Step 2: Flush the Toilet

Flush the toilet to drain the tank. This will make it easier to work on the fill valve.

Step 3: Remove the Old Fill Valve

Locate the fill valve at the bottom of the tank. It’s typically a brass or plastic cylinder with a diaphragm inside. Use the adjustable wrench to loosen the nut that holds the fill valve in place. Once the nut is loose, you can pull the fill valve out of the tank.

Step 4: Install the New Fill Valve

Take the new fill valve and insert it into the hole in the bottom of the tank. Tighten the nut to secure the fill valve in place.

Step 5: Adjust the Fill Valve

Once the fill valve is installed, you need to adjust it so that it fills the tank to the correct level. There is usually a screw on the top of the fill valve that you can turn to adjust the water level. Turn the screw clockwise to lower the water level and counterclockwise to raise it.

Step 6: Test the Fill Valve

Turn on the water supply and flush the toilet to test the fill valve. Make sure that the tank fills to the correct level and that there are no leaks.

Step 7: Reinstall the Toilet Seat

Once the fill valve is working properly, you can reinstall the toilet seat.

Tips:

• If you’re not sure what type of fill valve you need, take the old one to the hardware store with you.
