would you advice draining all 3 rads changing each locksheild to a trv then refill the system. do i need each bleed valve open on then rads whilst filling?
Thanks
ok so i should just turn off the boiler and drain the water from the rad via valve on the flow side this will allow the excess in the pipes to escape and depressurise? when i come to refill the system my boiler has a key i insert and turn a knob fill/add pressure is there anything i should do to...
