Problem: Toilet Runs Constantly
Possible Solutions:
- Lift chain is disconnected from handle lever or is kinked preventing the flush ball or flap from properly seating
- Lift wire is kinked or binding
- Float ball is rubbing on side of tank
- Plunger or diaphragm type ballcock is not shutting off completely. Bend float arm to push float ball more into water.
- Water level in tank is too high and water is running into overflow pipe. Adjust water level in tank.
- Flush valve not sealing. Inspect tank ball or flapper ball and replace if worn or soft. See Repairing a Leaky Toilet Tank Flush Valve
- Make sure tank ball lift wire is straight and that tank ball is dropping onto the center of the flush valve opening.
- Replace leaky float ball.
- Replace faulty ballcock.
