Before I go and do this I thought I'd ask here. My pump seems to be
making
a bit of a racket whilst the system is warming up - the noise gets less
once
the house is warm.
The pump is running at it's slowest speed. Is it safe to crack it up
to 2
or 3 to see if that gets rid of the noise or am I likely to get burst
pipes
or rads with the increased water flow.
Sorry for what looks like a completely basic question.
Thanks.
Dave.


If the sound is a slight hammering or ticking noise, then it could just
be
the pipework heating up and expanding.


A "slight hammering", now there's a phrase to conjure with!

That's as opposed to a BigWallop. :-))
