Unclog Your Flushometer Woes: A Step-by-Step Guide to Changing It

Changing a flushometer may seem like a daunting task, but with the right tools and a little bit of know-how, it’s a job that most homeowners can tackle themselves. In this comprehensive guide, we’ll walk you through the entire process, from gathering materials to flushing the new flushometer for the first time.

Tools and Materials You’ll Need:

• New flushometer
• Adjustable wrench
• Plumber’s putty
• Rags
• Bucket or bowl

Step-by-Step Instructions:

1. Turn Off the Water Supply:

Locate the water supply valve behind the toilet and turn it off clockwise. Flush the toilet to drain any remaining water in the tank.

2. Disconnect the Water Supply Line:

Use an adjustable wrench to loosen the nuts connecting the water supply line to the flushometer. Be careful not to overtighten.

3. Remove the Old Flushometer:

Hold the top of the flushometer and turn it counterclockwise to loosen it. Once it’s loose, lift it off the toilet tank.

4. Clean the Tank Surface:

Use a rag to clean the surface of the toilet tank where the new flushometer will be installed. Remove any old plumber’s putty or debris.

5. Apply Plumber’s Putty:

Roll a rope of plumber’s putty and apply it to the bottom of the new flushometer. This will create a watertight seal.

6. Install the New Flushometer:

Carefully place the new flushometer onto the toilet tank, aligning the mounting bolts. Turn it clockwise to tighten it.

7. Connect the Water Supply Line:

Hand-tighten the nuts connecting the water supply line to the flushometer. Use an adjustable wrench to further tighten them, but avoid overtightening.

8. Turn on the Water Supply:

Turn on the water supply valve behind the toilet. Check for any leaks at the connections.

9. Adjust the Water Level:

Lift the flapper valve on the inside of the toilet tank and adjust the fill valve screw until the water level reaches the desired height.

10. Flush the Toilet:

Flush the toilet several times to test the new flushometer. Make sure it flushes properly and there are no leaks.

Troubleshooting Common Flushometer Problems:

1. Toilet Won’t Flush:

• Check the water supply to ensure it’s turned on.
• Inspect the flapper valve for damage or debris that may be preventing it from sealing properly.
• Clean the flush valve diaphragm or replace it if necessary.

2. Toilet Runs Continuously:

• Adjust the fill valve screw to lower the water level in the tank.
• Replace the flapper valve if it’s damaged or worn.
• Check the flush valve diaphragm for leaks and replace it if needed.

3. Weak Flush:

• Increase the water pressure by adjusting the fill valve screw.
• Clean the flush valve diaphragm or replace it if clogged.
• Inspect the flush valve jets for debris and remove any obstructions.
