has my central heating pump started to seize/jam up?
my central heating pump does not appear to be working (myson) i have loosened the plastic nut on the front of the pump (i have not taken it out)and the pump has started to buzz i think the pump is trying to work but the radiators are only warm,can i take the plastic nut right out and try to move the centre of the pump manually.
Why not replace with new one you can get for £35 or less drain out system un do big nut if you can shut valve on each side than you do not to have to drain system or the easy way to buy mason pump and un do four screws and just change head , make sure you switch off power from main to connect wire
