I've a 4 zone heating, baseboard, hot water. The circulation pump of
one of the zones makes grinding noises, which makes the impression to
me it won't last much longer.
My question is, is the replacement of such a pump a job that I can do
myself or do I need some heating guy to come here? What are the things
I should look out for?
Thanks for any advise,
Wilko
