Hello all and festive greetings..
I think my central heating pump may be seized. Having searched on here for advice on previous threads, I am aware that the pump could possibly be freed by turning the impeller with a screwdriver. My stupid question is whether the pump needs to be isolated using the valves either side first? Reason I ask is that I have partially unscrewed the central screw on the pump in order to access the inner shaft and, as expected, some water came out. However, it doesn't seem to stop coming our hence the stupid question....
