I have moved into a house with an older mixer gravity-fed shower and I'd like to install a shower pump. The hot water take-off is from the top of the cylinder as you would expect. The cold feed comes down from the loft to the floor of the airing cupboard then takes a U-turn back up to the height of the mixer. Why would they do that? Is it to equalise the h/c pressure or did the plumber have shares in copper pipe? There is very little spare room in the airing cupboard so I want to 'simplify' the additional pipework to the booster pump if possible.
