OK then.....I'll go round to me mums and try it on her radiator first. She will be pleased. If your kidding (and i hope you are) how do I really do it?
I have checked to see if its fully off, and I believe it is. If it is in the off position then have you any other ideas as to what may cause the high pressure? Can I lower it?
Yes.......I do have a plumber coming to fit the new 'part' but would like to know if it is dangerous in its current state. Lets assume the plumber wont arrive til next week.
The Story so far.....Moved into new home and found the radiators needed bleeding. After doing this, I rebalanced the pressure to approx 1.0 using filling loop. Next day the pressure has risen to 3.0 and has stayed there. There is a leak coming from below the boiler (plumber has ordered part?)...
