Valve that shuts off water to heater matrix is not opening ? Blockage in matrix?
-- Stuart
you say it may be blocked,but why when i take of the hose the water comes out
You said it only comes out at "very high revs", when the water pump is maxed out, maybe overcoming whatever the blockage or hindrance is.

i will take matrix out and see what i can do cheers let you know how i got on
Auxiliary drive belt loose, water pump on the blink? DaveK.
belt tight new pump&stat getting fed up
took matrix out water flowing through it fine ,water seems to be struggling just to get around hose ,no kinks or blackages took hoses off ok any suggestions
I don't understand how you can say "water seems to be struggling just to get around hose" yet also say "no blockages". How do you know there is no blockage somewhere?
