20mm UV Water Treatment System
A complete filtration, disinfection and start-up package for rainwater throughout your home
This professionally installed package combines pre-filtration, UV disinfection and essential system sanitisation to help deliver clean, clear rainwater throughout your home. The UV system includes filtration to remove fine sediment before the water passes through the UV chamber and a fault alarm that provides an immediate warning if UV protection drops.
Your package includes
- 20mm UV disinfection unit: premium UV steriliser with an integrated fault alarm.
- Dual-stage pre-filtration housing: heavy-duty 10 in x 2.5 in housing to reduce dirt and sediment before UV treatment.
- 12-month cartridge supply: one year of premium 1-micron string-wound filters and carbon filter cartridges.
- Initial plumbing biocide flush: treats existing taps and pipework before commissioning.
- Water tank disinfection: sanitises the storage tank before the new system begins operation.
A clean start matters
Tank disinfection and the plumbing biocide flush are completed before the UV system is commissioned. This removes established contamination from the existing system, allowing the new filtration and UV equipment to begin from a properly sanitised starting point.
