What is ultra-violet light?

Ultraviolet light is at the invisible, violet end of the light spectrum. Although we cannot see UV light, we are exposed to UV rays from all light sources, including the sun.

A distinctive trait of UV light is the range of its wavelengths, they are between 200 and 300 nanometers (billionths of a meter) and are categorised as germicidal which means they are capable of inactivating microorganisms such as bacteria and viruses. This ability has allowed the spread of UV light as an environmentally friendly, chemical-free and highly effective option ensures pure and safe drinking water.


How does UV light work?

UV-C rays pierce the cells of harmful bacteria and viruses in our drinking water, destroying their ability to reproduce. Without this ability, these organisms die and no longer pose a health threat. It is a simple but very effective process, with the system destroying 99.99% of harmful microorganisms.


What are the benefits of using UV?

For decades, chlorine has been successful in water treatment. However some organisms such as cryptosporidium and giardia are chlorine-resistant. Ultraviolet sterilisation is the ideal way of eliminating any waterborne bacteria or viruses while avoiding harmful disinfection by-products.

2 x 10” Jumbo Housings and mounting brackets

1 x 10” Jumbo 20 Micron Filter

Can I install the unit myself?

No. The unit must be installed by a certified plumber.


Will it use a lot of energy?

No – it uses around the same amount of energy as a 60 watt light bulb, making UV sterilisation a cost effective way to increase water quality.


How many litres of water per minute will the unit sterilise?

Up to 41 litres per minute, ideal for residential applications.


What is the warranty on this product?

UV Lamps have a 12 month pro-rata warranty.

The power supply has a 5 year pro-rata warranty if a manufacturing fault is found to be the cause. Warranty is void if the fault is due to installation or moisture damage.


How often is the tube and filters replaced?

The UV tube and two pleated filters are all replaced annually. Although the pleated filters may be washed up to three times a year if required to remove sediment build-up.


Can it be installed outside?

No. The UV unit must be installed somewhere weather and moisture proof. If you wish to install the unit outside, you may be required to build an enclosure for this.


Do I need this to comply with the building code?

If you are building a new house that has an untreated water supply, you are required by law to treat the water to a safe standard.  Clause G12 of the Building Code states that water intended for human consumption, food preparation, utensil washing or oral hygiene must be potable.


How do I know if my water is infected or not?

Your water quality can change from day to day. There are symptoms that may indicate that your water is contaminated including:
