Why is my hot water cylinder overflow dripping?
When an overflow pipe is dripping or running with water, one of the most common causes is a problem with a float valve. Float valves are found in toilet cisterns, cold water tanks and central heating feed and expansion tanks. When the water in the tank is used, its level goes down and so does the ball and arm.
What causes a hot water cylinder to wear down?
On low pressure systems your incoming pressure is reduced with a pressure reducing valve. This valve may wear down over time eventually allowing more pressure through than the vacuum relief valve (the vacuum relief may also be the cause) or open vent height may be allowed for. In this case maintenance or replacement will be required.
