Hello guys need a bit of advice.. I do some maintenance in a nursing home. The top floor has very bad water pressure from the hot. There is a few splurts of air out of the taps but nothing major. Each bath and sink are fitted with mixing valves. The cold feed leaves the storage tank drops 3 floors to a large galvanised cylinder and then has to travel back up to the 3rd floor. No pump fitted but I've been informed it's worked fine in the past?? The only other thing I can see is the cold feed to cylinder runs about 25 metres along the ceiling joists level which would trap a bit of air.. Any suggestions?
