Dual Pumps
Dual Stainless Steel Pumps: The system features two submersible pumps operating in a duty/standby-assist setup.
Backup & Assistance: One pump acts as the primary unit, while the second automatically steps in to assist during high demand or take over completely if a fault occurs.
Adjustable Control: Managed by a unique pressure switch control panel with customizable start/stop pressures to suit a wide range of applications.
Professional Mains Water Back Up
In any direct system, the mains water back up is to the main rainwater tank. Flow to the tank should match the demand to ensure the pump cannot run dry. Our professional mains water back up with industrial specification solenoid valve and protective mesh inlet ensures trouble free operation and continuous supply of water to the property.
Advanced filtration
The 0.28mm (280 micron) fine filtration provided by the WISY VORTEX filter protects the tank from any debris and offers additional benefits such as increased oxygen for clearer water, and easy safe cleaning. This prevents any debris getting into the tank and breaking down in the water. The Wisy Vortex filter is unique in its operation and with its patented design, is unrivalled in terms of quality.
Discover moreRainTech® GRP Underground Tanks
UK made tanks manufactured to BS 4994 from high grade GRP; 100% glass fibre / resin mix with no fillers. These tanks are manufactured to our own specification to comply fully with BS 8515. This includes our unique Multisiphon overflow trap with built-in backflow protection.
Note: It is a requirement of the British Standard for rainwater harvesting that all rainwater tanks are protected against backflow. Most tanks are supplied without this feature, so it has to be added by the installer downstream of the tank itself. Our RainTech® tanks are always fitted with backflow protection.
