I'm hoping someone can give me some advice regarding my combi boiler. Recently it's been losing pressure (dropping down to zero). When this happens, I top it up to about 1-1.5 bar but over the course of 1-2 weeks, it drops back down to zero.
I've searched the forums before regarding this & have seen 2 possible causes for this:
1. a leak in a pipe 2. a dodgy pressure release valve
without taking the carpet up, it's hard to check the pipes, so I've been keeping an eye on the outlet pipe. Here's what I've seen:
at about 2 bar, there are occasional drips at about 3 bar, there are constant drips at just over 3 bar, there's a constant trickle
I've got 2 questions I thought I'd ask before getting a plumber out:
1. are these pressures normal/typical? 2. should I be getting the drips / trickles at those pressures?
thanks in advance, Brian
