The Sentry 203 is an all in one water filtration system, where water passes through four different filtration stages to reduce sediment, odor, colour and taste issues. The treatment then ends with a dose of UV to destroy harmful micro-organisms including E-coli, Cryptosporidium, Campylobacter and Giardia.

This stainless steel unit comes completely assembled for “plug and play” functionality, needing only to be wall mounted.

Can be configured for left or right side water entry.


This system is ideal for medium to large homes where water may be contaminated with “faecal coliforms”. This can be from bird and possum waste on roofs and gutters or live stock run off entering streams and shallow bores.
