The new Grundfos PMRain is an interconnect device that allows you to utilise your harvested rainwater for toilet flushing and laundry applications, with the added benefit of mains water backup. The new PMRain also features a tank only garden outlet, to ensure you only use rainwater for your garden watering.
The PMRain is used in conjunction with a Grundfos pump. The pump itself is only activated when rainwater is being drawn from the tank. It does not operate when switched to mains.
The PMRain automatically starts when a demand is sensed – for example the flushing of a toilet or filling a washing machine - and will switch over to mains water when your tank is empty or in the case of an electrical failure.
Grundfos has incorporated a specially designed valve eliminating the need for an in-tank float – drastically decreasing installation time.
The PMRain interconnect device can be fitted to one of our reliable JP or JPRain range of pressure pumps, making it suitable for above ground tanks
The PMRain interconnect device can be fitted to a submersible SB pump for in tank pump installations with either a wall or tank mount kit, making it a great solution for above and below ground tanks.
