Gathering the Essentials:

Before you begin, ensure you have the necessary items on hand. Here’s what you’ll need:

– New fill valve assembly
– Adjustable wrench
– Sponge or towel

1. Shut Off Water Supply:

Locate the water supply valve near the base of the toilet and turn it off. After that, flush the toilet to empty the tank.

2. Remove Lid and Water:

Take off the toilet tank lid and carefully set it aside. Use a sponge or towel to soak up any remaining water in the tank.

3. Detach Old Assembly:

Using an adjustable wrench, loosen and unscrew the mounting nut that holds the old fill valve assembly in place. Once the nut is removed, take out the old valve assembly.

4. Prepare the New Assembly:

Adjust the height of the new fill valve assembly so that the marking on top is at least one inch above the overflow tube in the toilet. This adjustment ensures optimal performance.

5. Install the New Valve:

Insert the shank of the new fill valve into the opening at the bottom of the tank. Push it downward while simultaneously tightening the lock nut located underneath the tank.

6. Refill Tube Adjustment:

Trim or bend the refill tube of the new assembly as required to ensure a proper fit.

7. Reattach the Ankle Adapter and Refill the Tube:

Connect the ankle adapter and refill tube to the overflow pipe in the toilet.

8. Reconnect the Supply Line:

Carefully reconnect the water supply line to the toilet tank. As the tank fills, keep an eye on the water level and ensure it’s functioning correctly.

9. Check for Leaks:

While the tank is filling, inspect all connections for leaks. If you notice any leaks, gently tighten the connections until the leak stops.

By following these steps, you can successfully replace the fill valve in your toilet. This straightforward repair not only addresses the running or leaking issue but also brings renewed efficiency to your bathroom fixtures.”
