Your tank. One clear water route.

01Collect & store

Start with your existing rainwater collection and storage arrangement, such as a tank or IBC.

02Filter on demand

Offgrid Rain combines a pre-strainer, three cartridge stages, brushless pump and UV-C. The system activates when water is drawn.

03Supply the outlets

Use the domestic filtered supply for washing and showering. A suitably pre-filtered branch can feed FinalStage RO and its separate drinking tap.

Offgrid Rain is filtration equipment. Roof collection, gutters, the storage tank and site pipework are not part of the unit. The optional accumulator is not supplied.

What should we check together?

Your water

  • How it is collected and stored
  • Tank capacity and condition
  • Any existing filtration or water test
  • Whether you need drinking water, domestic use or both

Your installation

  • Distance and height from the tank
  • How many outlets may run together
  • Power supply and mounting space
  • Any existing pump or accumulator

Rainwater questions.

Can I connect it to an IBC?

An IBC can form part of the storage arrangement. Send us its position, outlet details and the outlets you want to supply so we can check the proposed connection.

Does Rain collect the water?

No. It treats water you have already collected. Your collection surface, storage tank and upstream pipework are separate from the filtration system.

Can I supply a larger or multi-storey property?

Tell us the layout and peak demand before choosing. The listed Rain system is described for suitable single-storey properties; a larger installation needs its own assessment.

Do I need a water test?

Source and storage conditions affect the required treatment. Share any results you already have, and tell us how you intend to use the water so the next steps can be agreed.

Planning a rainwater supply?

Send a photo or sketch showing the tank, proposed system position and the outlets you want to supply.
