Stuart Turner Monsoon - Negative 4.0 Bar Twin Pump

The Stuart Turner Monsoon negative 4.0 bar twin pump is designed to be system friendly, and will offer years of trouble free service.

When installed into an open vented hot / cold water system, where outlets are either above or below the level of the cold water cistern, it will have the effect of raising the water pressure with the equivalent of raising the cold water cistern 40 metres above it's current position.

Pressure switch operated, it has the performance to boost the water pressure to the whole of your home, and is ideal when used in conjunction with high pressure taps and showers when high pressure and high flow rates are required. 


A negative twin pump can be used to:

  • Boost hot and cold water services to complete bathrooms, cloakrooms and kitchens.
  • Pressurise the supply in applications such as loft conversions, where the outlets are higher than the water source
