Fix a Running Toilet

⏱️30 min💰$12–30🟢Beginner4.9 (445 reviews)

A running toilet wastes 200 gallons a day. Fix it in 30 minutes with a $12 kit.

Open the tank

Remove the lid and look inside. The flapper, float, or fill valve is usually the culprit.

Check the flapper

Push down on the flapper. If the running stops, the flapper needs replacing.

Replace the flapper

Unhook the old flapper from the overflow tube ears and snap on the new one.

Adjust the float

The water level should be 1" below the overflow tube. Bend or adjust the float arm.
