Shower pumps are designed for use in gravity fed systems – where you have a cold water tank (usually located in the loft) and a hot water tank (usually a copper cylinder clad with insulation in an airing cupboard).
Negative Head (aka Universal) – These are designed for boosting showers and taps level with or above your cold water tank and are designed to start and stop using a pressure switch.
Positive Head (aka Standard) – These are designed for boosting showers and taps below your cold water tank and are designed to start and stop using a flow switch.
Single Ended – These will only boost one water supply. This can either be your hot, your cold, or a blended supply (a mix of hot and cold).
Twin Ended – These are our most popular pumps and are designed to boost your hot and cold supply at the same time – ideal for most showers.
