Connect Chain and Test Flush — Install New Flapper and Prepare for Fill Valve

How to Replace a Toilet Fill Valve and Flapper · Step 3 of 6
In this video
Hook the toilet's flapper chain onto one of the holes on the end of the new lever arm. The second hole from the inside is a good starting point. The goal is to have minimal slack in the chain when the flapper is closed. Once the chain is connected, test the toilet by flushing it. Observe that the handle returns to its original position and the flapper creates a proper seal. Place the tank lid back on and perform a final test flush.
Goal: Repair Running Toilet (Chain Adjustment)
- If the toilet doesn't flush completely, try moving the chain to a hole further out on the lever arm. If the flapper doesn't close, ensure there isn't too much tension on the chain.

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.
