The Fill Valve is Broken
The fill valve controls water flow. It refills the tank. It also stops water. A faulty fill valve keeps filling. Water then goes down the overflow tube. This causes the running sound. Adjust or replace the valve. This stops the constant flow.
The Float is Set Too High
The float stops the fill valve. It rises with the water. When water is high, it stops. If the float is too high, it fails. The valve keeps filling the tank. Water goes into the overflow. Adjust the float’s position. Lower it slightly. This should fix the problem.
The Overflow Tube is Cracked
The overflow tube is important. It prevents tank overflow. If it cracks, water leaks out. Water goes into the bowl. This triggers the fill valve. Check the overflow tube carefully. A crack needs a new tube. This is a necessary repair.
The Handle is Loose
The handle connects to the flapper. It lifts the flapper to flush. A loose handle might not lift. It might not drop fully. This can keep the flapper open. Check the handle’s connection. Tighten it if needed. Ensure it moves freely.
