WHAT FAILS HERE
Heating faults common in Crayford
Crayford's pattern of home extensions frequently leads to pressure-related faults, where the original heating system wasn't adequately resized for the new layout.
01
Boiler losing pressure repeatedly after a property extension
Adding radiators to a new room increases the system's water volume, which can overwhelm a pre-existing or faulty expansion vessel. An engineer will test the vessel's pre-charge pressure and check for leaks on the new pipework.
02
Pressure relief valve discharging water outside
If the expansion vessel has failed or the system pressure is set too high, often after alterations, the safety valve will open to relieve pressure. Diagnosis involves checking the vessel's diaphragm and ensuring the filling loop is correctly isolated.
