pressure dial on expansion vessel

emmkat · 7 Oct 2014

hi

i have drained down a pressurised heating system until no more water came through and noticed that the pressure gauge had not dropped. i did the job knowing there was no water in the system. when i went to refill iturned it on and off quickly and the needle went right down to zero. so i started refilling and it got to about half a bar and the pressure relief valve kicked in. so i think the pressure gauge has had it. my question is can i change the pressure gauge without draining down. i would appreciate a quick response as i am on the job as i am typing this message.

Thanks
