How to Replace a Toilet Fill Valve and Flapper · Step 6 of 6
In this video
Reconnect the lift chain to the trip lever arm, securing it with the pin or clip. Turn the water supply valve back on by turning it counter-clockwise. Allow the tank to completely refill. To verify the repair, take note of the water level against a reference point, like the top of the overflow tube. Wait for about 30 minutes, then check the water level again. It should not have dropped. Finally, perform a test flush to ensure everything works correctly.
Goal: Test the repair
- The chain should have a small amount of slack, about 1-2 beads, when the flapper is closed. Too much slack can cause a weak flush, while too little can prevent the seal from closing properly.

FAQs
What are the most important safety precautions I should take when replacing a toilet fill valve and flapper?
Always start by turning off the water supply to the toilet completely using the shut-off valve behind the toilet. Flush the toilet to drain the tank and bowl as much as possible. Have towels and a bucket ready to catch any residual water, and consider wearing gloves for hygiene and grip.
The project is rated 'beginner' and '2 hours.' Is this realistic for someone who has never done plumbing before?
Yes, this project is genuinely beginner-friendly. It primarily involves unscrewing and screwing on nuts by hand or with simple tools. While 2 hours is a good estimate, allow yourself a bit more time if it's your first time to read instructions carefully and avoid rushing. It's a great project to build confidence in DIY plumbing.
Do I need the specific Husky wrench and Channellock pliers mentioned, or are other adjustable wrenches sufficient?
You do not need those exact brands. Any good quality adjustable wrench (10-12 inches) will be essential for securing the fill valve nut. Slip-joint pliers are very helpful for removing stubborn connections but often an adjustable wrench can handle most tasks. Ensure your tools are in good working order.
After replacing the fill valve and flapper, my toilet is still running or leaking. What should I check first?
First, ensure the fill valve's water level adjustment is set correctly; the water should stop filling about 1 inch below the top of the overflow tube. Next, check that the flapper seats perfectly over the flush valve opening and that its chain isn't too tight or too loose, which could prevent a proper seal. Also, double-check that the fill valve mounting nut underneath the tank is tightened sufficiently but not overtightened.
