Self priming single pump booster sets complete with pressure switch and mild steel accumulator vessel. Water supply is not always enough to supply the correct amount of water at a suitable pressure, so the best and most affordable solution to solve water deficiency problems is to install a pumped booster system via a ‘break’ tank. These systems are specifically designed to boost the pressure of the water supply and deliver the correct amount of water to all outlets. The pre-set pressure switch enables it to automatically start and stop the pump. Do not allow to run dry.
