How to Replace a Toilet Fill Valve: A Step-by-Step DIY Guide · Step 4 of 4
In this video
Slowly turn the water supply back on and check for leaks around the base of the tank. As the tank fills, you may need to adjust the water level. Use a screwdriver to turn the adjustment screw on top of the fill valve to raise or lower the float, which sets the final water level. The water should stop filling about 1 inch below the top of the overflow pipe. Attach the small refill tube from the nipple on the fill valve to the clip on the overflow pipe. This tube is what refills the toilet bowl after a flush. Finally, give the toilet a test flush to ensure everything is working correctly and the bowl fills to the proper level.
Goal: Set correct water level and test operation

FAQs
What specific tools will I need for this project, and are there any alternatives if I don't have them?
You'll primarily need an adjustable wrench, like the Crescent 12 in. model, to loosen and tighten the lock nut. While pliers can sometimes work, an adjustable wrench provides better grip and reduces the risk of stripping the nut. A sponge, such as the HDX Multi-Purpose Sponge, is also very helpful for soaking up residual water.
What is the most critical safety step I need to take before starting to replace the fill valve?
The most critical step is to turn off the water supply to the toilet completely, usually via the shut-off valve on the wall behind the toilet. Once the water is off, flush the toilet to empty the tank as much as possible, using a sponge for any remaining water. This prevents leaks and makes the job much cleaner.
How long should this DIY project take for someone with no prior plumbing experience, and what's the typical cost for materials?
For a beginner, replacing a toilet fill valve typically takes about 30 to 60 minutes from start to finish, including setup and cleanup. The Korky QuietFill Toilet Fill Valve mentioned costs approximately $15-$25, making this a very affordable repair.
After installing the new fill valve, my toilet keeps running or the water level is too high/low. How do I fix this?
First, check the float height on your new fill valve; it should be adjusted so the water level stops just below the overflow tube. If it keeps running, ensure the refill tube is properly inserted into the overflow pipe and that the lock nut under the tank is securely tightened to prevent external leaks.
