Hi there,
I had a circulating pump replaced a few months ago (was very old) and it ran ok for a while, but then burnt out the coils (blew the fuse etc).
At the time I thought it might have been either the crap in my system or water that was dripping onto the pump from a leaking valve.
I replaced the pump myself last weekend (a replacement that the plummer got replaced by the shop and I've been flushing the system this weekend to find that the diverting valve looks like it is playing up (Honeywell Sundial Y Plan).
It seems to work ok most of the time, but then sometimes when I turn off the hot water from the controller (so that just the central heating is running) the pump seems to stop.
I was wondering if this could have burnt out the previous pumps where the water has nowhere to go and straining?
Cheers, Mark.
