Product Description

Enduramaxx Rainwater Harvesting Kit B – 450m² Roof Area

The Enduramaxx Rainwater Harvesting Kit B is a complete filtration system designed to maximise the quality of harvested rainwater for roof catchment areas of up to 450m². Suitable for use with the Enduramaxx Rainwater Harvesting Tank range, the kit efficiently filters debris before water enters the storage tank, helping to provide cleaner stored rainwater for garden watering and a wide range of non-potable applications.

The system includes a Combi Filter Unit, Calmed Inlet and Siphon Overflow, working together to maintain excellent water quality while reducing maintenance requirements. The two-stage filtration process removes leaves, dirt and debris before water enters the tank, while the calmed inlet delivers water gently to the base of the tank, minimising disturbance to settled sediment and helping to oxygenate stored water.

The siphon overflow incorporates a skimming inlet that removes floating debris, oils and surface contaminants before excess water leaves the tank, helping to keep stored rainwater cleaner for longer.

Designed for easy installation and reliable year-round performance, the filter insert can be removed for simple cleaning, while the self-cleaning design helps minimise maintenance.

Please note: Wall bracket not included. It is recommended that the filter is cleaned several times a year, depending on local weather conditions and rainfall levels.
