Pressure relief valves that are there to protect the heating system from over pressure.

It is advised that they are replaced every 5 years for insurance purposes. These PRV’s were found to be from 2007!!!

Our apprentice Lewis, supervised by Liam Harrison replaced 4x 2inch valves. Lewis was shown how to clean pipework in preparation for the new valves and how to joint the fittings.
