      Can I install a system myself?

      Yes, it comes with a full instruction manual, however we do advise that you have it checked and signed off by a registered master plumber.

      Can these systems be installed outside?

      We offer a variety of systems tailored for different applications, and according to plumbers, ours is the only truly 'outside compatible' option available.

      Our systems feature an all-weather impervious alloy cover, ensuring durability. Additionally, the power supply is fully encased within its waterproof box, preventing moisture infiltration. We use Gel-filled ballasts to isolate the circuitry effectively.

      Moreover, our systems come with added protection, including surge protectors and RCBOs. These features not only prevent electrical damage but also assist in identifying faults.

      Does it need 240 Volts?

      Yes, it has a UV lamp to kill the bacteria, which requires input voltage of between 110 to 240 volts, which is stepped up by the ballast to over 400 volts.

      How long does the whole UV system last?

      Depending on its location, the system should provide a minimum of 20 years of service. It's essential to understand the three component groups:

      1. Consumables: Includes seals and lamp cartridges, typically replaced every 6 to 12 months.
      2. Replaceables: Involves items like quartz sleeves, filter o-rings, power supply, and jumbo filters, which are typically replaced every 3 to 10 years.
      3. Durables: Long-lasting components such as backing boards, covers, chambers, brackets, and pipe fittings, designed to last up to 20 years.

      Each component group plays a vital role in the system's functionality and longevity.

      How much does it cost to install a filtration system?

      Depending on where the system is to be installed and the type of connection piping used, it can be from as little as $250+GST.
