How To Replace A Toilet Fill Valve – Fluidmaster?

A toilet fill valve is a critical component of your toilet that regulates the flow of water into the tank. If your toilet is leaking, running constantly, or not filling properly, it’s likely that the fill valve is to blame. Replacing a toilet fill valve is a relatively simple DIY project that can be completed in about 30 minutes.

Here’s a step-by-step guide on how to replace a toilet fill valve:

  1. Turn off the water supply to the toilet. This is usually located behind the toilet, near the floor.
  2. Flush the toilet to drain the water from the tank.
  3. Remove the old fill valve. There are two main types of fill valves: ball valves and flapper valves. Ball valves are typically found on older toilets, while flapper valves are more common on newer models. To remove a ball valve, simply unscrew the nut that holds it in place. To remove a flapper valve, you will need to first remove the toilet tank lid. Then, locate the flapper valve and carefully pry it up with a flathead screwdriver.
  4. Install the new fill valve. Make sure that the new fill valve is compatible with your toilet. Once you have the correct fill valve, follow the manufacturer’s instructions for installation.
  5. Turn on the water supply to the toilet.
  6. Flush the toilet to test the new fill valve.

If you’re having trouble replacing the fill valve, or if you’re not sure what you’re doing, it’s best to call a professional plumber.

Troubleshooting

If your toilet is still not working properly after replacing the fill valve, there are a few things you can check:

  • Make sure that the new fill valve is installed correctly.
  • Check the water supply to the toilet. Make sure that the valve is turned on and that there is no blockage in the line.
  • Check the float arm. The float arm should be adjusted so that it is just below the overflow tube. If the float arm is too high, it will allow too much water to flow into the tank. If the float arm is too low, it will not allow enough water to flow into the tank.
  • Check the flapper valve. The flapper valve should be seated properly against the flush valve. If the flapper valve is not seated properly, it will not seal properly and water will leak into the bowl.

If you’ve checked all of these things and your toilet is still not working properly, it’s best to call a professional plumber.

Additional Tips

  • When replacing a toilet fill valve, it’s a good idea to replace the other toilet parts that are also wear and tear items, such as the toilet seat, the flush valve, and the water supply line.
  • If you’re not comfortable working on your own toilet, it’s best to call a professional plumber.
  • Toilet fill valves are available at most hardware stores.
  • The average cost to replace a toilet fill valve is between $50 and $100.
