Hello everyone,
My first post!
I've been reading on the forums for 3 weeks, since my girlfriend and I bought our first house, but with all the wealth of information on here, I've not needed to post before as many of my questions have already been answered.
However, as stated in the subject heading, our Glow Worm 30 Ci combi boiler has started to lose pressure.
When we got the house, the pressure read 1.4-1.6 bar for two weeks, but on screwing in some floor boards last Sunday, I foolishly hit into a central heating water pipe. The plumber came round and for £45 replaced a small section of pipe and an elbow. He re-pressurised the system to 1.0 bar, checked his work didn't leak and went off but told us to keep an eye on the pressure.
After letting it settle down, I got the pressure back up to around 1.4-1.6 again. Having looked yesterday morning, it had crept down to 1.1 bar and this morning was reading 1.0 bar.
IS the boiler just regulating itself down to the normal 1.0 bar, or is there something wrong somewhere?
Would a tiny leak be a likely cause of dropping around 0.1 bar a day?
Would the plumbers replacement joint be the first place to look, if so, or have I even more foolishly screwed into another section of pipe?
D'oh - we had all the carpets fitted yesterday!
After doing some searching, I found this thread:
//www.diynot.com/forums/viewtopic.php?p=293565
Gasman1015 suggested "Determine whether its a system leak or boiler by isolating flow and return
valves below boiler, while the boiler is off, leave for two hours."
Is this a good way to check for system leaks, and if so, how do I do it?
ANY help greatly appreciated - and please keep the technical jargon as simple as possible!
