The Hydrophor Pump regulates and maintains a constant water pressure to the shower nozzles. This is very important when operating multiple showers.The Hydrophor pump will automatically turn on when any valve at the shower is opened and a drop in water pressure has occurred. When the valves are closed  at the showers the pump will automatically shut off. The water supply source is typically connected to the Hydrophor pump and the Hydrophor pump then supplies water at the proper flow and pressure to the shower nozzles.
