Hi all, first time on here.
I have a myson apollo 30 si wall mounted boiler with a potterton EP3001 programmer,potterton prt2 room thermostat,potterton ptt2 water temp thermostat, british gas motorised actuator (recently replaced including 3 port valve) and a grundfos selectric ups 15-50 water pump.
The actuator was replaced for what was thought to be the problem, which was persistent clicking when the system turned on to heat up.
The noise is still apparent and seems to be coming from the pump.
I would like some advice as to what in the pump can cause this noise please.
All assistance greatly appreciated. Thanks in advance. Chris
