Negative Head Shower Pumps
(16 products)Negative head shower pumps are ideal for cold-water tank outlets that are below or near-level with the shower head. They work by creating a negative vacuum, pulling water through from the tank and pushing it towards the shower. Negative shower pumps have a pressure switch to recognise when the shower is turned on even when water is not flowing. If the cold-water tank is less than 600mm above the shower head, or natural water flow is less than 2 litres per minute, a negative head pump should be considered.
