FAQs

How does UV sterilisation purify water?

Ultraviolet (UV-C) light at a wavelength of 254 nm penetrates micro-organisms and disrupts their DNA, preventing them from reproducing. When water flows through a stainless-steel reaction chamber that houses a UV lamp, pathogens such as bacteria, viruses, Giardia and Cryptosporidium are rendered harmless in a fraction of a second—without adding any chemicals or altering taste and odour.

Why is UV water purification a smart choice for homes and businesses in Mascot?

Mascot’s water is generally safe, but ageing pipes, rain events and back-flow incidents can introduce microbial contamination between the treatment plant and your tap. A point-of-entry UV system provides an extra layer of protection, ensuring every tap, shower and appliance in your building receives microbiologically safe water. This is especially valuable for food outlets near Sydney Airport, childcare centres, medical suites and households with immune-compromised members.

What contaminants does UV sterilisation remove?

UV targets living micro-organisms—bacteria (e.g., E. coli, Salmonella), viruses (e.g., rotavirus, hepatitis-A) and protozoa (Giardia, Cryptosporidium). It does not remove chemicals, heavy metals, sediments or tastes and odours. For comprehensive treatment, UV units are often paired with pre-filters that handle particulate matter, chlorine, lead or other specific contaminants.

Do I need pre-filtration before installing a UV system?

Yes. UV light is most effective when the water is clear. Suspended solids can shield microbes from UV exposure, and hardness can create scale on the quartz sleeve. We recommend at least a 5 µm sediment cartridge upstream of the UV chamber, and where chlorine is present, a carbon block filter to protect the stainless components and improve taste.

How often should the UV lamp and quartz sleeve be serviced?

UV lamps gradually lose intensity and must be replaced every 9–12 months of continuous use, even if they still light up. The quartz sleeve should be removed and cleaned every 6 months to remove scale and film; replace it every 2–3 years or if damaged. Our Mascot plumbing team offers scheduled maintenance plans so you don’t have to remember the dates.

What are the running costs and energy usage of a UV water purifier?

Most residential UV units draw 25–60 watts—similar to an LED light bulb—costing roughly $30–$50 per year in electricity at current NSW rates. Annual consumables include one lamp ($100–$150) and, if applicable, two sediment/carbon cartridges ($30–$80). Compared with buying bottled water or dealing with water-borne illness, the ongoing cost is minimal while providing whole-building protection.
