Baxi HE133 weird pressure loss.

Cheerychops · 29 Dec 2010

I have a Baxi HE133 CH boiler which whilst still working - heating - seems to be losing pressure almost every day. I can refill it using the tap fitted below the boiler but why does it keep losing pressure. How can it be fixed?

I have looked at a few posts and see some comments about the expansion tank???

Check the obvious first.....leaks on system/rads.

Then check the prv outlet pipe to see if it's dripping. May just need replacing the prv or the exp vessel charging rather than replacing
