Monsoon Negative Pumps

Suitable for installation into an open vented hot and cold water system. Negative pumps do not require a gravity flow to start, making them ideal for use in loft conversions and apartments where a gravity flow of
0.6 l/min cannot be achieved. A Monsoon negative pump will work where either positive or negative conditions exist.
