Fixed a leaky ball c*ck value and then drained the central heating to clean it out as there seems to be a blockage in the downstairs radiator (in the kitchen).
There was sludge in the header tank which has filled back up again, no longer overflowing as it did with the broked valve. However the radiators are not filling with water and when i turned on the hot water the pump was dry running.
How can i get the water circulating again! I think the header tanks sludge has caused a new blockage... though i added the chemiclas to clean the sludge... will it unblock overnight!
Any help gratefull recieved! A cold showered cheesy toastie!
