I am in the process of instally a shower cabinet whixg says it needs 3 BAR to operated correctly. I can see that power shower pumps are available to supply 3 BAR but have 3 questions:
1. The hot & cold water tanks are 20 feet above the hight of the shower head but to get to the shower the pipework will need to drop to ground level (26 feet below tank), travel horizontally 50 feet. Does this need to be in 22mm or could I get away with 15mm?
2. Given the head, what size pump (if any) would I need to supply 3 BARR?
3. The pumps I have looked at (screwfix) all say tank feed only, does this mean that I can't take the cold feed from the mains rather than the cold tank?
Many thanks, guess I'll be running another pipe (22mm).
That link has raised another issue in the siting of the pump. We already have a power shower in an upstairs bathroom and pump is located close to the hot water cylinder. Will I have to uprate this pump so that it can supply both showers or should I install another close to the new shower?
