I'm soon to be fitting a Surrey Flange to the top of my hot water cylinder as the water pressure to my shower is poor and inconsistent despite having a pump recently installed. The pressure before fitting the pump (as left by the plumber who installed it) was extremely poor.
Question: Will I need a pump on the new set up? The bottom of the cold water tank to the shower head is only about 600mm but I can reduce the number of bends and use 22mm pipe if required. If not can I get a pump that operates next to the tank in the loft as many (like my old one) require about 2m of head.
There is also a lot of air getting into the hot water and I'd like to solve this at the same time if possible. Currently the pipe from the top of the hot water cylinder goes vertically up and vents over the cold water tank in the loft. Hot water is drawn off horizontally about
200mm above the cylinder.Question: Is this set up ok or should the pipes be angled somehow to prevent air being sucked in?
