Simple explanations for plumbing problems

Filling loop left open

After us the valves on the filling loop should be closed, the metal braided filling loop removed and the valves capped.  The majority of people don’t do this so there is always a chance that the valves can be opened accidentally or be faulty.  This can allow too much pressure to develop in the system which may cause the metal pipe near the boiler to overflow.

The first step is to turn the taps so they are in the off position. If its a round tap turn it clockwise.  If it has a lever turn it so that is not in line and at 90 degrees with the body of the valve.  If it has been accidentally turned on you will hear the water flowing and hear the flow stop when you turn the valve to the correct position.

It doesn’t need to be as pronounced as this to cause the pressure to go up, even slightly open is enough.
