Full Australian WaterMark Certification

This Water Filtration System is certified to WaterMark Standards AS/NZS 3497 under Certificate Number 23247. WaterMark is the standard that is required by law for a qualified plumber in Australia to install any item on municipal town water. All products used under this certification will give you peace of mind knowing that your water filter complies with Australian plumbing codes. Our WaterMark filtration systems are hand assembled here in Australia and are batch tested to ensure quality and workmanship for your filtration products.

This kit has been put together to meet the demands of many customers using tank water.

Tank water will always require filtration as it isn't treated like municipal water supplies. The most cost-effective and total solution to do so is to use UV Sterilisation, which will ensure 100% eradication of all Bacteria and Viruses from your house water supply.

The only alternative would be to use an under-sink filter for drinking water, which is effective at stopping cysts such as giardia but won't protect you from harmful bacteria or viruses such as E-Coli which can enter the water through frogs excrement. On top of this, all other taps (i.e the shower, basins, and other taps) won't be treated so you can still be exposed to these viruses and bacteria through means other than ingestion.

Kit Contains:

  • GT1-9WMW - WaterMark Twin Whole House Water Filter Steel Bracket
  • GT2-28N - 5 Micron Polyspun Sediment Water Filter Cartridge
  • GT4-19P - 5 Micron Pure 100% Coconut Carbon Block Filter
  • GT7-9K - 50L/Min Ultraviolet Sanitation System

Twin Whole House Water Filter:

5-micron Poly Spun Cartridge:

Poly Spun is the best type of filtration you can get. They do not accumulate bacteria as much as other materials, as well as being high flow and low pressure drop. Effective in all applications. 5 micron is a reasonably fine filtration and would be suited on high quality bore water or town water or in front of RO's.

100% Virgin Polypropylene material - Compatible for Our Watermark Certified Systems

Purefer Polypropylene filters are made using a unique single nozzle manufacturing process, where a single nozzle blows melted polypropylene onto a spinning 5-micron filter core. As more Polypropylene is blown, the filter diameter gradually widens and the outer density of the filter decreases.

This unique manufacturing process gives Purefer filters a true Gradient Density that allows for a greater dirt holding capacity and higher filtration efficiency compared to standard melt blown filters made from multiple nozzle blowers.

5 micron PURE Carbon Block Cartridge:

Pure Coconut Carbon Block Filters are made from a combination of high-performance coconut shell carbon, unique binders and industry leading manufacturing processes to deliver trade quality carbon block filters. They deliver exceptionally low pressure drop while maintaining a high dirt holding capacity with excellent contaminant reduction capabilities.

Pure Carbon Blocks are registered in compliance with NSF/ANSI 42, 53, and 61 for several things, including VOC’s, THM’s, Lead & Heavy Metal Reduction, Chloramine Reduction & Chlorine Taste & Odour reduction. This also includes meeting standards of purity & safety of the materials used.

The perfect carbon block filter is made from 100% Coconut Shell Carbon, which creates what many believe to be sweetest tasting water. The unique pore structure of this carbon is well suited for chemical absorption, including VOC's, while reducing chlorine and chemicals that contribute to taste and odour.

Ultraviolet Sanitation System:

UV Water Sanitation is by far the most important filtration process when it comes to rainwater treatment. Rainwater harbours bacteria of all types but in some cases, much more harmful bacteria may be present in the tank. E-Coli is a common bacterium in tank water and is due mostly to Frogs in and around your tanks/catchment. Ultraviolet sanitation works by breaking down the cell wall of a micro-organism allowing oxidation to occur which in turn prevents the bacteria from multiplying until it is finally eradicated. Ultraviolet filtration is a chemical-free solution to water sanitation creating no by-products in the water.

​We recommend adding the optional UV Thermal Relief Valve for any situation where the UV system is installed and water is not continuously running through the system. This will prevent the UV system from overheating and damaging the seals

If your water quality parameters do not meet these criteria, please contact the distributor for pre-treatment recommendations.

Required:  Pre-treatment must include at least a 5-micron sediment filter installed prior to the unit in order to ensure that particles capable of shielding pathogens are removed from the water prior to entering the system.  A shut-off valve must be installed prior to the unit in order to turn the water off for servicing and to ensure the flow is restricted to the parameters of the unit. Ensure adequate clearance at the lamp connection end of the unit in order to safely remove the lamp from the chamber for servicing and lamp replacement. Space required is at least the length of the UV chamber

Please Note: The Second photo is an example photo only, not all items included in the photo are supplied with this kit, you will only receive the items that are listed above. You will need to source your own fittings to install the system to your required specifications. Because all setups are different, we do not supply the fittings with this kit. Please refer to the description for items supplied with this kit.

The UV ballast is not waterproof and should be protected from water/moisture at all times.

If you have any questions at all regarding the installation or the included items/added extras, please contact us prior to purchasing.

UV System Maintenence Notes:

Ultraviolet systems are rated based on a dosage level of UV-C radiation into the water (mJ/cm²), with 30mJ/cm² being the standard level of disinfection and a minimum dose of 40mJ/cm² required to comply with Australian Drinking Water Guidelines. Our lamps are rated with a 9000 hour (1 year) lifespan, after which point the lamp will naturally degrade and the level of radiation produced by the lamp cannot be guaranteed.

The UV lamp sits inside a quartz thimble, which protects the electrical components of the lamp from making contact with the water. We specifically use quartz (fused silica) for this application because it is strong, exhibits thermal resistance, and has excellent UV transmission properties.

However, over time, metal ions fused within the silica structure of the quartz thimble interfere with the UV-C radiation produced by the lamp, which reduces the UV transparency of the glass and causes it to become fragile. This process is called solarization.

Tannin, bio-film, algae, and scale can also build up on the outside of the glass thimble, further preventing ultraviolet light produced by the lamp from penetrating through the thimble, and impairing the system's ability to sanitize the water passing through.

Thus, we recommend replacing the lamp every 12 months, and the thimble every 1-2 years.

Technical Data

UV systems are not designed to be turned on and off. Doing this may shorten your lamp life. Lamps should be changed every year. The lamp may still be working, but after 1 year, the power may not be able to kill all bacteria. The Quartz thimble should be replaced every 2 years. If hardness is high it is recommended to service and clean the UV thimble every 6 months or as required to remove and scale that may build up.
