Add to Quote


  • Compact system ideal for tight and narrow sites.
  • Small footprint that would suit almost any site conditions.
  • Easy to install with reduced excavation requirements.
  • 4″ Inlet and outlet for “Whole of House” and commercial applications.
  • Can spread the greywater over a large garden area (combined with the 6 stations GF Rotor and the GF Drip Tube the system can cover a garden area as large as 480 square metres).
  • Low once-a-year maintenance requirement (if the self-cleaning mechanism is selected). Monthly maintenance is required with the standard unit.
  • Due to the tank size and shape, the desludging maintenance work prescribed for in tank-based systems is not required.
  • Having the system installed in two stages minimises the risk of theft of equipment from the site during the building process.
  • Easily adjustable height level. Can be used with very deep sewer pipes (up to 3 metres).
  • Two-Stage installs in new homes reduce installation costs.
  • Builders Kit – is to be installed by a licensed plumber at the pre-lay stage of construction for new homes on a cement foundation.
  • Finishing kit – can be installed by a Grey Flow accredited installer at the house finishing stage before laying of paving.
