How to repair a running toilet
Identifying the problem
The first step in repairing a running toilet is to identify the source of the problem. Typically, a running toilet is caused by a faulty flap valve or a malfunctioning fill valve. The flap valve controls the flow of water from the tank to the bowl, while the fill valve regulates the water level in the tank.
Checking the flap valve
Start by lifting the lid of the toilet tank and observing the flapper valve. If the flapper valve appears worn, deformed or damaged, it may not create an adequate seal, causing water leakage. To solve the problem, turn off the water supply to the toilet and empty the tank by flushing. Remove the old flap valve and replace it with a new one. Make sure that the new flap valve is aligned correctly and that it creates a tight seal when closed.
Inspecting the filling valve
If the flap valve is functioning properly, the problem may lie in the filling valve. Check the filling valve for signs of leakage or a faulty flotation mechanism. Adjust the float to ensure that it is at the appropriate water level, according to the manufacturer's instructions. If the fill valve is damaged or malfunctioning, it may need to be replaced.
Cleaning or replacing the flush valve seat
Toilet malfunction can sometimes be caused by the accumulation of mineral deposits or debris on the flush valve seat. To solve the problem, turn off the water supply and flush the tank. Use a sponge or cloth to thoroughly clean the drain valve seat. If the seat is damaged or worn, it may need to be replaced to ensure a proper seal.
Testing and adjustment
After making any necessary repairs or replacements, open the water supply and let the tank fill up. Observe the toilet for signs of continuous operation or leaks.
