Fix Faulty Flush Systems

Fix faulty flush systems

Toilet cisterns overflow because the inlet valve doesn’t shut off when the water reaches its correct level. In this case, check the first four points listed below, but if water runs continuously from the cistern into the pan, the outlet valve is the problem, so check the last three points.

If the water level is too high, bend the brass float arm down a little to lower the water level in the cistern.

The inlet valve washer may be faulty, so replace it.

The inlet valve may be clogged, so dismantle and clean it.

The float may be fouling the inside of the cistern, so bend the float arm so the ball is clear of all obstacles.

Dirt or water-borne minerals may clog the valve, which you can fix quickly by simply cleaning it out.

In old cisterns there is a tiny groove in the brass plate under the suction washer, which may need cleaning out. Check if this is the case.

A reduced flush can result from either the water level setting being too low, so adjust the brass float arm upwards, or the outlet valve suction washer may be faulty, so replace it. If the latter is the case, you’ll hear the valve fall back into place just after flushing starts.
