Pressure tanks are also called accumulator tanks as they accumulate or store pressurised water when installed between the pump and the tap. A pre-pressurised pressure tank is a very important addition to your pump system and will give you a smoother water flow, accumulate any excess in pressure in the line, quieten pump operation, reduce pump cycling pulsation and water hammer and will reduce your power bills and extend the life of your pump. A must for every pressurised pump set up!
