Hello,
My glowworm 30cxi was fitted back in 2005 and until a couple of weeks ago I have not had any problems with it. However, just before Christmas I decided to bleed my radiators and since then the pressure has started to continually drop. I am having to repressurize by using the refill loop every 1.5 to 2 days as once the pressure drops below 0.7 bars, the boiler ceases to work. I repressurize to 1.4 bars.
My observations since I've been trying to figure out what's happening are:
Assuming the expansion vessel isn't the problem, what else could be at fault. My guess would be the prv but would the symptoms I'm seeing be consistent with that?
If anyone on here has any comments / ideas of what the problem is or what I can try next to identify a solution it'd be appreciated.
Thanks.

My observations since I've been trying to figure out what's happening are:
- 1. The pressure only drops when the CH is off.
- 2. The pressure tends to increase (!) when the CH is on. When increasing it's only by approx 0.2 bars and then it drops more than that in the time the CH is off, but I'm a bit stumped as to why the pressure would increase and then drop back down again.
