Frequently asked questions

UV disinfection neutralises bacteria, viruses and protozoa without adding any chemical to the water, so there's no taste, odour, or chemical by-product to manage — chlorine, by contrast, leaves a residual and can produce disinfection by-products, but does offer ongoing protection further down the pipe network, which UV doesn't.

No — UV only targets microorganisms. It doesn't remove chlorine, taste, odour, sediment, or dissolved chemicals, so it's typically installed alongside sediment and carbon filtration as part of a complete treatment train, not as a standalone solution.

UV systems are rated for a maximum flow rate at which they still deliver an effective dose — sizing too small a system for your peak household or commercial flow will under-dose the water. Tell us your peak flow rate (or number of bathrooms/outlets) and we can help confirm the right system size.

Yes — UV disinfection only works while the lamp is powered and up to temperature, so water drawn during or immediately after a power interruption may not be fully disinfected. Systems with a solenoid valve or flow sensor can shut off flow until the lamp reaches full output, which is worth considering for critical applications.

UV is one of the most widely used disinfection methods for private and borehole supplies, provided the water is properly pre-filtered for sediment and iron first — untreated cloudy or iron-laden water reduces UV effectiveness and can foul the quartz sleeve quickly. Start with a water test so we can confirm what pre-treatment, if any, is needed.
