My money is on a simple airlock, as said above, forcing mains cold through the HW system will clear it.
In which case the flow from the Hot Water Cylinder is fine, so the problem is elsewhere. As said, air lock would be initial suspect.Yes, sorry I should have elaborated. The how water comes on instantly, as normal in the downstairs bathroom.
He's not fat - it's just stupid small! Seriously it's around 14" square and I have no idea who the hell can fit through that other than a small child! We looked at increasing the size of it but its that size because the joists are that far apart! Its an old bungalow that's been converted to have an upper floor at some point in the past.
Unfortunately whoever told you that is talking nonsense I'm afraid.they added 4 or 5 (!) smaller tanks instead which are not providing the necessary pressure to the system
Given your reply, I do appreciate that's not what what you want to hear. It can be a little demoralising when other information doesn't tally with what you believe to be a professional opinion on your issue. Honestly I don't say these things to annoy, as a professional that has experience in these types of systems, I can only give you the benefit of that experience. It gets really annoying when supposed professionals give clients really duff information because it sounds right and we have to burst that bubble.Thanks.
