So, after sorting out my leaking PRV on monday all seemed to be well. Then i noticed that the pressure does drop slightly.
I think i've tallied up that its actually when i request hot water. If my pressure on the CH is 1bar (when boiler not in use), i call for hot water and then notice that the pressure drop nearly a 1/4 of a bar. Once i switch off the hot hot water, the pressure goes back up but not to the original level.
Is this anything to be concerned about or is simply because the systek has recently been drained and refilled from a complete drain down etc? I've currently got a bad over the blow out pipe leading from the PRV and there's nothing coming out there now.
Its a vokera compact 24 boiler btw.
Thanks
Pete
