Hello.
Not to long ago I took off a radiator to paint behind, since I put it on for about 2 weeks the pressure kept dropping to zero, I topped it up when I noticed it had happened, then 1 day it over pressurised and went to max, I then released some water out of the radiator, this happened a few times until I got it serviced and the prv replaced, and the expansion vessel replaced, it is still doing it but not going to max, it goes just below max but above the min/max threshold line, over timeframe of 48hrs.
I am reading the digital display on the front.
When the heating comes on it doesn’t spike and then stay high, it’s a gradual thing.
It also drips from the 15mm pipe outside.
The boiler is 10 years old.
I am going to get the plumber back round but I like to understand these things myself, anyone have any clues ?
Someone suggested it maybe the filling loop faulty valve, I’m not so sure because it doesn’t go to max.
