Nothing out of the prv - or any radiator vents.
We have ruled out (almost?) everything apart from the supply pipework. Can't argue that whoever did the pipework made a mistake ..... BUT
what we REALLY need to know is "can we use a sealing compound (like "RadWeld") in a heating system?"
... or is that more likely to do something nasty to valves and similar "gubbins"?
