Thanks.. are the isolating valves inside the pump?. I see it is necessary to completely drain the system to replace the pump.

Thanks .. I best get the pump checked sometime soon.

Hi, My Sevrvo warm Elite 50 boiler constantly hums quite loudly when it is running, regardless of whether the flame is on or off. At times the humming quietens a bit. Can any one pls help?
