I have a 10 year old Myson CP63 pump fitted to my 14 rad central heating system which is set to speed setting number 3.
I tried to turn it down to number 1 or 2 but I don't think that these 2 speeds are working because I can not hear it running at all.
Do I need to buy a new pump and is so does it have to be the same make or can I put another equivelent one on without having to change any fittings?
