Why does my hot water system overflow?
Hot water systems Water expands when heated, pressure builds up in the tank and is released through the overflow pipe. So water dripping or running from the valve can be a sign of a normal, functioning system. However, not all leaking overflow pipes are occurring due to normal pressure build up.
What does it mean if the overflow pipe is dripping?
When an overflow pipe is dripping or running with water, one of the most common causes is a problem with a float valve.
