Can anyone identify this noise? -

It's a sort of high pitch metallic rattling, happens all the time,
and has started since I drained and refilled the closed combi system.


Ahem, found the cause - it's the casing of the pressure gauge
vibrating against its plastic cover. Think I'll just leave it for the
time being

Maybe push a bit of sponge between the two surfaces, to damp it.

Thanks - just tried. All the noise seems to be generated from within the
gauge. Wedging some rubber stuff in changes the pitch a little.

I'm inclined to let it fail and replace as needed (£40) in the hope that
nothing catastrophic happens meantime.


Quick update - I've come across this now and it seems to be a 'design
flaw' - one fix is blu-tack!

The other issue I've had with this Ideal Logic is the mains water inlet
joint. Looks like large compression fitting to me. The installer said
he's had to replace several - I've needed to pinch-tighten it a couple
of times over the years.
