I don't have a water tank so I guess yes it is mains pressure. If you do a quick search for my previous posts (one thread from a couple of years ago) there are some photos there of the boiler which I think is a combi.
OK then I definitely won't get the scourer out in case that's the straw that breaks the camel's back. Also scared now that the stopcock will come off in my hand!
I suppose now we get to the interesting question: if I have no local recommendations, what's the best way to find a plumber? Still, at least I am armed with some helpful information so he can't suck his teeth and tell me that I need a whole new central heating system and I'll believe him .
