Safety First

Before you begin, it’s essential to take safety precautions. Always wear gloves when handling plumbing fixtures, and turn off the water supply to your toilet before starting any work.

Step-by-Step Instructions

1. Remove the Water Supply

Using an adjustable wrench, turn off the water supply valve located behind the toilet. Flush the toilet to drain the water in the tank.

2. Disconnect the Water Supply Line

Unscrew the water supply line from the fill valve at the bottom of the tank. Use a sponge or cloth to absorb any remaining water.

3. Remove the Tank Lid

Lift the tank lid off the tank.

4. Disconnect the Flush Valve

Locate the two nuts that connect the flush valve to the tank. Use an adjustable wrench to loosen and remove these nuts. Carefully lift the flush valve out of the tank.

5. Install the New Flush Valve

Place the new flush valve into the tank. Align the holes in the valve with the holes in the tank, and insert the bolts. Tighten the nuts onto the bolts using an adjustable wrench.

6. Connect the Water Supply Line

Attach the water supply line to the fill valve on the new flush valve. Tighten the connection using an adjustable wrench.

7. Turn on the Water Supply

Turn on the water supply valve behind the toilet. Open the lid of the tank and check for leaks. If there are no leaks, replace the tank lid.

8. Test the Flush Valve

Flush the toilet to test the new flush valve. Ensure both the full and half flushes work properly.

Pro Tips

• If you encounter stubborn bolts, use a penetrating oil to loosen them.
• When tightening the nuts, don’t overtighten them. This can damage the flush valve or the tank.
