The 3 Stage Big Blue Water Filtration System with 55W UV Steriliser – Pre-Plumbed PVC Version is a high-performance water treatment solution designed for easy installation and reliable operation. Built on the proven Big Blue 20” triple filtration platform, this unit is pre-assembled with 32mm and 1” PVC pipework, significantly reducing installation time and complexity. With standard 1” male inlet and outlet connections, it allows for straightforward integration into existing plumbing systems, making it ideal for homeowners, installers, and commercial applications.

This system combines multi-stage filtration with powerful UV sterilisation to deliver comprehensive water purification. The sediment filter removes dirt, sand, and particulates, while the carbon block reduces chlorine, odours, and organic contaminants. The final polishing stage enhances water clarity before passing through the 55W UV steriliser, which neutralises harmful bacteria and pathogens without the use of chemicals. Designed for borehole water, municipal supply, and rainwater systems, this unit ensures consistent, high-quality water while maintaining an eco-friendly, low-maintenance operation.
