I have a job coming up in a house where the primary F&E is in the loft and has a tap pouring into the top of it (!) and also a combined feed and vent in 15mm. Am planning to fit FOV, add a 22mm vent, and an overflow.
My concern is that the combined cold water storage and indirect-cylinder feed cistern is on the ground floor and therefore at a lower height (pressure) than the primary cistern.
I have advised the customer that it would be a good idea to move the latter cistern into the loft to prevent contamination of the stored water in the event of cylinder coil failure. Customer likes idea and keen to get better water pressure, but reluctant to have upheaval at present - wants to rent house out.
I can't find anything in the Water Regulations that specifically says that the water level in the F&E should be higher than that in the Cold Water Storage (and cylinder feed) Cistern, but may be I'm not looking in the right place. I've said I'll do just the F&E... reluctantly - IF there isn't a regulation on this.
Is having the F&E water level lower a regulation, or just good practice? Many thanks if anyone can help!
