Not much info but here goes...Can only fit a pump to stored water systems (cold water storage tank and hot water cylinder) Height of cwst gives natural head pressure, often enough to power a shower on its own but if not sufficient then add a pump. Pumps vary in size but a basic ct50 salamander is often enough for most folks. Correct pipework is the key to smooth operation. Work out how many litres a minute the pump works at versus how many litres your hot water cylinder will hold and your cwst, should be able to get at least a 10 minute shower without running out of water, if its borderline changes need to be made, or leave the pump out
