How to Cure Ballvalve Float Problems

CURING FLOAT PROBLEMS

♦ If the float develops a leak, the valve won’t shut off at the correct point. Unscrew the float, empty out the water, and patch the hole with epoxy putty or tie a plastic bag over it. Replace as soon as possible.

You can cure this by fitting a purpose-made damper to the float arm. Alternatively, hang a punctured yoghurt carton in the tank, suspended from the float arm by a length of galvanized wire.

♦ In a toilet cistern, the float may catch on the flushing mechanism causing the valve to jam open. If necessary bend a brass arm so that the float is free to move throughout its travel; plastic arms generally have a choice of fitting positions.
