Tools and Materials

Before embarking on this adventure, gather the following tools and materials:

• Adjustable wrench
• Pliers
• Screwdriver
• New flush valve
• Plumber’s tape
• Rags

Safety Precautions

As with any plumbing task, safety should be your top priority. Before beginning, turn off the water supply to the toilet by locating the shut-off valve behind the toilet or at the main water line. Flush the toilet to release any remaining water in the tank.

Step-by-Step Instructions

1. Remove the Tank Lid:

Gently lift the tank lid and place it aside.

2. Disconnect the Fill Valve:

Locate the fill valve, which is connected to the bottom of the tank and fills it with water. Use pliers to disconnect the water supply line from the fill valve.

3. Unbolt the Flush Valve:

Use an adjustable wrench to loosen the bolts that secure the flush valve to the bottom of the tank. There are typically two or three bolts.

4. Remove the Flush Valve:

Once the bolts are loosened, carefully lift the flush valve straight up and out of the tank.

5. Wrap Plumber’s Tape:

Take the new flush valve and wrap several layers of plumber’s tape around the threads of the flange, where it will connect to the tank. This will create a watertight seal.

6. Install the New Flush Valve:

Align the new flush valve with the hole in the bottom of the tank and gently insert it. Hand-tighten the bolts to secure the valve in place.

7. Reconnect the Fill Valve:

Reattach the water supply line to the fill valve and turn on the water supply.

8. Adjust the Water Level:

Adjust the water level in the tank by bending the float arm of the fill valve. The water level should be about an inch below the top of the overflow tube.

9. Test the Flush:

Flush the toilet to test the new flush valve. Check for any leaks or improper flushing.

Troubleshooting

1. Flush Valve Leaking:

• Check if the plumber’s tape is properly wrapped around the threads.
• Tighten the bolts that secure the flush valve.
• Replace the flush valve if it’s damaged.

2. Toilet Not Flushing Properly:

• Adjust the water level in the tank.
• Inspect the flapper valve for damage or debris.
• Clean the flush valve diaphragm.

3. Toilet Constantly Running:

• Check if the flapper valve is properly seated.
• Adjust the fill valve to prevent overfilling.
• Replace the fill valve if it’s malfunctioning.

Questions You May Have

1. How often should I replace my toilet bowl flush valve?

Generally, flush valves should be replaced every 5-7 years or as needed if they start leaking or malfunctioning.
