Why Replace a Toilet Fill Valve Korky?

The toilet fill valve korky, also known as the flapper, is a crucial component that controls the flow of water into the toilet tank. Over time, the korky can become worn or damaged, leading to leaks, running toilets, and higher water bills.

Tools and Materials You’ll Need:

• New toilet fill valve korky
• Adjustable wrench
• Screwdriver
• Bucket or bowl
• Plumber’s putty (optional)

Step-by-Step Replacement Instructions:

1. Turn Off Water Supply: Locate the water supply valve behind the toilet and turn it clockwise to shut off the water flow.

2. Flush the Toilet: Flush the toilet to drain the tank.

3. Disconnect Water Supply Line: Use an adjustable wrench to loosen the nut connecting the water supply line to the fill valve.

4. Remove Old Fill Valve: Unscrew the locknut that secures the fill valve to the tank using a screwdriver. Gently pull the fill valve out of the tank.

5. Install New Korky: Apply a thin layer of plumber’s putty around the base of the new korky and insert it into the fill valve.

6. Reinsert Fill Valve: Insert the fill valve with the new korky into the tank and tighten the locknut using a screwdriver.

7. Reconnect Water Supply Line: Hand-tighten the nut connecting the water supply line to the fill valve. Use the adjustable wrench to further tighten it, but avoid overtightening.

8. Adjust Water Level: Open the water supply valve and adjust the fill valve screw until the water level in the tank reaches the desired height.

9. Test the Fill Valve: Flush the toilet again and observe if the tank fills up properly and stops at the appropriate level.

Troubleshooting Tips:

• Leaking Fill Valve: If the fill valve continues to leak after replacement, check for a loose connection or a damaged korky.
• Running Toilet: If the toilet keeps running after replacement, adjust the fill valve screw to lower the water level.
