If your home is suffering from seriously low water pressure there is something you can do about it. And it’s surprisingly simple! Fitting a twin impeller Salamander shower pump is perfect for resolving low water pressure woes. They boost both the hot and cold supplies equally so you can finally have that powerful shower or wash your hands with ease. The higher the bar pressure the more power you’ll receive so expect a large increase with a 2.0 bar or above pump.
