Negative Head Shower Pumps
(3 products)Negative head shower pumps are designed for cold-water tank outlets that are below or near-level with the shower head. They function by creating a negative vacuum which draws water through from the tank and pushes it towards the shower. They work with pressurisation which pushes a 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 then a negative head pump should be considered.
