Product Description

The ideal accompaniment to the Enduramaxx Rainwater Harvesting Water Tank range, this rainwater filter system is designed for roof spaces up to a maximum of 200m² (per kit).

Kit contents;

  • Garden filter unit
  • Siphon overflow
  • Calmed inlet

Product Specification

  • A total retention rainwater filter with integrated dirt collecting basket
  • Designed for roof sizes up to a maximum of 200 sq metres (per kit)
  • Easily removable filter basket
  • Suitable for garden watering
  • Ideal where no sewer connection exists
  • Filter unit weight 2.2 kg
  • Siphon overflow with skimming inlet
  • Siphon overflow pipe to fit a 130 mm hole in storage tank wall
  • Calmed inlet to prevent incoming water disturbing any sediment in tank
  • Calmed inlet also ensures fresh water is supplied to lower area of the tank resulting in complete and regular replenishment of stored water

Rainwater flows through the piping onto the filter cartridge. Dirt is retained in the dirt collecting basket. Water that passes through the filter then flows into the rainwater tank via a calmed outlet – this outlet is designed to undertake a secondary cleaning phase by allowing the water to enter the tank is a more controlled manner, minimising turbulence and therefore minimising the amount of disruption to potential sediment that may be present at the bottom of the tank.

Calmed rainwater entering the tank supplies oxygen to the water resting at the lower end of the tank, keeping it fresh by prevention of anaerobic decomposition.

Finally the overflow siphon, which incorporates a skimming inlet, skims the surface water inside of the storage tank removing further debris, oils and other floating contaminants thereby increasing the quality of the stored water.

Suitable for garden watering as well as a large range of other uses, the filter kit helps to retain as much collected water as possible, whilst providing an efficient filtration system and regular replenishment of stored water.

Note – it is recommended that the filter be cleaned several times a year dependant on how much rainfall there is. Refer to installation instructions for guidance on correct fitting.
