HydroStore 4400 litre 'Garden Harvest' rainwater harvesting system allows the connection of a hose to the pump within the tank to provide recycled rainwater for irrigating lawns/gardens and car washing, etc...

It consists of the H1500 and H2900 HydroStore tanks (including internal components). A length of pipe and two threaded fittings are required to complete the link between the primary tank and the holding tank.

Key benefits

  • High impact strength at low temperatures  
  • Calmed inlet reduces turbulence to tank sediment, improving water quality to property
  • Pressure-sensitive pump (turns off if no demand), dry-run protected (turns off if no water detected) for extended service life
  • Pump outlet capable of delivering 2500ltr/hour, nominal 35m head, and 3.5 bar pressure to guarantee reliable, constant and efficient supply
  • Stress free mouldings provide extra strength
  • Lightweight, easy to handle
  • Integrated handling points
  • Corrosion resistant   
  • Low maintenance
  • UV protected
  • Recyclable polyethylene
