Finicky Fill Valve
If your toilet keeps running, check the fill valve before looking into other parts. The fill valve in your toilet is responsible for refilling your tank every time you flush, so when it fails, water will continue to run into your tank and through the overflow tube.
Fixing the Fill Valve: Repair or Replace?
First things first: test out your fill valve! Simply try lifting the float to see how that affects the water in the tank. The water level should be a 1/4 inch below the overflow tube. Some toilets have a fill height marked on the tank. If the fill valve is overfilling, it’s likely your float height needs to be adjusted. This simple repair should get things back to normal.
If testing or adjusting your float doesn’t solve the problem, it might be time to replace the fill valve. Over time, parts of your fill valve can break, leak, or get worn down and cause issues. When parts of your fill valve are broken, it’s best to replace the entire fill valve system to make sure your toilet can run properly.
