A L Plumbing and Heating Overflow
Common problem with cold water storage tanks in the roof space is a dripping overflow.
The overflow pipe exits the roof space under the eaves (under the gutter line).
Even worse is a steady flow of water from this pipe.
can occur for a number of reasons:
- The ball float valve is not adjusted correctly.
- The rubber diaphragm is perished.
- The float is split.
- A build up of limescale within the valve preventing it from working correctly.
Similar problems can occur with the overflow pipe from your toilet cistern, which
usually passes though the wall in the same area as the bathroom waste pipes. (Some
modern toilet cisterns now overflow internally straight into the toilet pan, which
saves extra pipework).
This is easier for a plumber to repair since it is not amongst suitcases and boxes
in a cramped loft!
