The 2nd engineer did recharge the expansion vessel but didn't change the prv as far as I know - should he have? After he recharged the expansion vessels he ran the heating for 10 mins or so and pointed out that the ch pressure only rose by about 0.2 bar, which was good. As my previous post...

Right... I had the company out on 8th April and they repressurised the expansion vessel. All seemed well at first... but shortly after I noticed that the system pressure is still dropping, albeit much more slowly. It goes from 1.2bar to about 0.3 in 3 or 4 days. Any ideas what this could be...

For my own curiosity (and to make sure I'm knowledgable enough to argue this with the plumbing company!), if it is the PRV that needs repressurising then where is the excess water going? I.e. how is it going from 1 bar when cold, to 3.5 bar when hot, then to .2 bar when cold? Thanks

Definately not the filler loop (have just disconnected to prove), thanks for the tip on charging the PV. Will let the system cool and give it a go.

I recently had a plumber out to sort a leaking radiator valve and during the job he tried to drain the system via the pressure release valve on the boiler but said it wasn't working so ended up bleeding a radiator. The next morning I noticed that the pressure guage was showing 0.5 bar so I...
