I fitted a replacement pump and moved a radiator in the bathroom. To do this I had to drain the system.
The new pump is running but I seem to have air locks and it will not draw the water down from the header tank in the roof. Any suggestions. I moved the little lever on the 3 way valve o the manual position rather than leave it in the default auto position. Any other ideas?
