Items Included In Kit

  • GT1-9TWM Triple Filter System with your choice of filters - For clarifying the water whilst improving the taste.
  • GT7-9K Ultraviolet Sanitation System - 50L/Min Standard - For sanitising water - kills 99.9% of bacteria, parasites, and viruses.

Tank water will always require filtration as it isn't treated like municipal water supplies. In our experience, the most cost-effective and total solution is to use UV Sterilisation, which will ensure 99.9% eradication of all Bacteria, Parasites, and Viruses from your house water supply.

INSTALLATION - Please note this system is WaterMark Certified to Australian Plumbing Standards (AS/NZS 3497), and will need to be installed by a licensed plumber. Simply order online with free shipping to your home, and once it arrives any local licensed plumber will be able to do the installation (the system also comes with instructions)! When calling around for quotes, be sure to ask about installing a "bypass" so you can still get water into your home when the time comes for filter changes! Normally, a whole house system will be installed after the pump and before the main water line goes into your property. Your plumber will need to source fittings to install the system to your required specifications - because all setups are different, we do not supply fittings with this kit. Please refer to the description for items supplied with this kit. Please note that the UV System (including the Stainless Steel Chamber + Power Supply) is not waterproof and should be protected from the weather/rain/water/moisture at all times. If you have any questions at all regarding the installation, items included with each kit, or the added extras, please contact us prior to purchasing.

Full Australian WaterMark Certification

All Water Filtration Systems included in this package are 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.

Do you have Copper Pipes + a Poly or Steel Tank, or a pH below 6.8? If so, please read the below important information to consider:

The issue of tank water acidity is of particular concern for customers with the poly/steel tank + copper pipes combo - this must be addressed in order to prevent copper pipe corrosion and pinhole leaks in your pipework later down the track (which is very costly to fix)! 

Nowadays many people are getting brand new Poly Rainwater tanks installed on their property. Rain water is commonly known to be in a very acidic state (around 5 pH) naturally, and it is only when it comes into contact with earth or other organic material that the pH rises to neutral and even alkaline levels. However when you have clean gutters and a new clean poly tank, there is no organic or inorganic matter to dissolve into the water to raise the pH, thus you are left with highly acidic water sitting in your tank. This can cause extensive health issues in the long term, but it may also affect your plumbing work throughout your house. Copper is known to be the worst-affected part of your house by acidic water - you will notice a blue/green tinge to the water which is a signal that copper is dissolving into your water. Acidic water works its way from the inside out and if left long enough untreated, may cause your entire copper pipework to fail and need replacing.

Have you checked for signs of copper pipe corrosion in your home? Above are some examples of copper pipe corrosion, which is easily detected by the presence of blue-green staining around drains, fixtures and faucets. In the worst-case scenario, copper pipe corrosion will start with pinhole leaks, progress to multiple holes, and will eventually require you to replace the entirety of the copper pipework of your home!

If you need to address this issue, please check out our Triple Whole House Rain Water + pH Treatment Filter System | Ultraviolet Sanitation to Kill Bacteria, Parasites & Viruses + pH Neutralising to Control Copper Pipe Corrosion (GT1-18-TRIPLE-KIT)

If your pH/copper pipework leaching is not an issue, please continue on!

FSA'S TANK WATER RECOMMENDATION + THINGS TO CONSIDER

  • FILTER SIZE + PUMP PRESSURE REQUIREMENTS - As the big blue housing is UV resistant, it can be installed in direct sunlight or in the shade. The 20" x 4.5" size of system enables the maximum surface area and contact time for sediment, chemical, taste and odour reduction, and the best possible flow rate to prevent water pressure problems (which can occur by selecting too small a system). This system is designed to handle high flow with a standard pump system up to 500 kPa (72 psi), so you should not notice any significant reduction in pressure during regular water usage for an average household with a decent pump. Please note: around 344kPa (50 psi) is the ideal minimum pressure required for use with this system - pump pressures lower than 275kPa (40 psi) may cause excessive pressure drop if installed alongside a whole house filtration system (i.e. low water pressure in showers). 
  • SHOULD I SELECT A TWIN OR TRIPLE WHOLE HOUSE FILTER SYSTEM?
    Twigs, leaves, sand, and dirt can be easily collected by a pleated filter, whilst ultra-fine particles (i.e. particles that are smaller than 100 micron, the width of a human hair) such as silt can clog up your carbon filter much quicker than anticipated and reduce your water pressure. If you have a lot of sediment in your tank, this system may be more suitable for your water conditions.
  • HOW TO USE A PRESSURE GAUGE?
    You may also wish to opt for a set of pressure gauges (especially if you have a lot of sediment in your tank) to help determine how clogged your filters are, and monitor the performance of your system. Simply mark the level of pressure on the gauge upon installation or when you install a new set of filters - reduced pressure over time indicates filter blockage. 

  • FILTER CHANGES AND MAINTENANCE - Lastly, we recommended filter changes on an annual basis, and offer a 12-monthly filter reminder email service to help you remember! Simply email info@filtersystemsaustralia.com.au when you place your order, and ask us to set you up with a filter reminder! Filter changes are easy enough – simply turn off the water going into the system, press down on the pressure relief valves, unscrew the sumps, replace the filters, screw it back up and turn the water back on! You may notice the water feels a bit "slippery" at first after installing new filters, but don't worry - this is normal and will go away quickly once enough water has run through the new filters. Also, if the water looks cloudy at first, again - don't stress! This is dissolved oxygen and it will go away quickly once enough water has run through the new filters.

Filter Options

Customise your filter system set up to suit your unique needs. Please read the below for a full breakdown of which filters to choose, and why*.

*Please note - the below recommendations are general information only and may not always suit your requirements. Please call us on 07 5597 4585 prior to purchase if you have any questions about your requirements.

Sediment Filters

  • This system comes standard with a 5 Micron Pleated (Washable) Sediment Pre-filter, and a 5 Micron Polyspun (Disposable) Sediment filter as backup. This set-up is ideal for those who get a lot of sediment in their tank.
  • 5 Micron is well suited for mains/town treated water and high-quality tank/bore** water.

Tank and bore** water are often contaminated with sticks, leaves, and rock sediment. In some cases, finely dissolved matter can even cause visible discolouration, build-up and staining, along with a foul taste and odour - and even a gritty texture in some rare cases! Installing a sediment filter also helps protect your pipes and carbon filters from getting blocked up with ultra-fine silt, whilst also preventing damage to the glass internals of the UV system.

 

5 Micron Pleated (Washable/Reusable) Sediment Filter (Standard with Kit)

  • Larger Surface Area Catches More Debris
  • Reusable/Washable
  • Ideal Pre-Filter for Tanks/Bores**

Pleated filters carry a much larger surface area than polyspun filters, and therefore they are able to catch a lot more debris. Simply remove the filter, clean, and re-use! Very popular for tank water when you have a lot of debris like leaves and dirt, particularly after a fresh rain. Pleated filters are also useful for bore water when you have a small amount of iron or manganese present, as pleated filters are easy and quick to clean. The washable pleats on this filter are designed to be washed and reinstalled. However, please consider that if this is drinking water you need to be careful not to overuse a pleated filter, because it will eventually gather bacterial contaminants and incur micro-tears. 

5 Micron Poly Spun (Polypropylene) Disposable Sediment Filters (Standard with Kit)

  • High Flow & Low Pressure Drop
  • Cost-Effective & Disposable

Poly Spun filters produce a high flow and low pressure drop, and do not accumulate bacteria as much as other materials. They are highly cost-effective and disposable. All of our poly spun filters are made of 100% Virgin Polypropylene. Polyspun filters are manufactured to create a gradient density that allows for excellent sediment-holding capacity and filtration efficiency.

 

Pure Brand 100% Coconut Carbon Filters

  • High Quality, 100% Coconut Shell Carbon that Produces "Sweet" Tasting Water
  • Excellent Contaminant Reduction Capacity for Common Chemical Health & Aesthetic issues such as Chlorine, Trihalomethanes, Volatile Organic Compounds, Pesticides, Herbicides, Tastes & Odours.
  • Recommended 12 Month Lifespan if (used on Municipal Treated Water - you may get less if used on particularly dirty/turbid/raw water).
  • Designed for Minimum Impact on Water Pressure

The perfect carbon block filter is made from 100% Coconut Shell Carbon, which creates what many believe to be the 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. Coconut Carbon provides a much higher volume of micropores than coal, wood, or lignite-based carbon, thus, resulting in a more effective removal of chemical contaminants such as trihalomethanes (THMs) in Chlorinated sources. The larger surface area provides a more effective method of filtering common contaminants such as chlorine, tastes and odour molecules. The unique raw material of the coconut shell and the carbon manufacturing process ensures exceptional hardness and low ash content.

Pure Brand's 100% Coconut Carbon Block Filters are made from a combination of high-performance coconut shell carbon, unique binders, and industry-leading manufacturing processes to deliver supreme-quality filtration. Expertly designed and manufactured, these filters deliver exceptionally low-pressure drop, resistance to sediment build-up, and excellent contaminant-reduction capabilities. Pure Carbon Blocks are registered in compliance with NSF/ANSI 42, 53, and 61 for several things, including VOCs, THMs, Lead & Heavy Metal Reduction, Chloramine Reduction & Chlorine Taste & Odour reduction. This also includes meeting incredibly high standards of purity and safety in the materials used.

Please see below for a full comparison of our range of Carbon Filters:

GT4-19CTO - 5 Micron Chlorine Taste & Odour Reduction Coconut Carbon (Budget Option for Improved Chlorine Taste & Odour Reduction in Tank Water)

  • CTO Carbon is our standard recommendation for chlorine reduction, improved sweet taste and reduced odour - great value and quality!

Chlorine is generally the biggest concern for those on municipal water or those who use chlorine to disinfect their tanks, due to the offensive chemical smell and taste it produces, along with potential health effects resulting from topical exposure or consumption. Whilst Chlorine is effective at sanitising bacteria and viruses, Volatile Organic Compounds and Disinfection By-Products such as Trihalomethanes (THM) and Chloroform can form when chlorine reacts with oxygen and other chemicals in solution. The Chlorine, Taste, and Odour cartridge will provide you with clean, great-tasting water free from nasty chemicals and remove or reduce any chemical smells in the water caused by free chlorine.

Bore/Tank Water** Filter Combo Example*:

Filter 1: 5 Micron Pleated OR 5 Micron Poly Spun Sediment Filter
Filter 2: 5 Micron CTO Carbon 
Filter 3: Ultraviolet Treatment

 

GT4-19BCC - 5 Micron Bacteriostatic (Silver Impregnated) Coconut Carbon Block (For Preventing Filter Biofouling in Raw/Tank/Bore** Water)

  • Ideal for Pre-Filtering tank** & Raw Water Prior to Ultraviolet Treatment.
  • Prevents Bacteria from Proliferating within the Cartridge.
It's important to note that Silver Impregnated Carbon is BACTERIOSTATIC - meaning that it inhibits or prevents the increase or growth of bacterial levels WITHIN the filter only. Silver Impregnated/Bacteriostatic Filters DO NOT sanitise, disinfect or remove bacteria from water. If this is your goal, further treatment is required - please refer to the note at the bottom of this page **FILTERING TANK AND BORE WATER - IMPORTANT INFORMATION BEFORE YOU ORDER**.
 
Contrary to popular belief, carbon does not filter out bacteria. Whilst carbon effectively removes odours and taste issues from water, carbon ash is actually a source of nourishment for bacteria, making wet carbon filters a breeding ground for microbial contamination (Note: this should not be an issue on mains water as Chlorination is designed to kill bacteria). This, unfortunately, causes biofouling of the filter cartridge which can lead to premature blockage (costing you hundreds of dollars to replace cartridges more frequently than you should have to), putrid tastes and odours and worse - illness as a result of ingesting the bacteria that has passed through the cartridge and into your drinking water! Using a rotten filter can make you seriously sick - so if in doubt - chuck it out!
 
Silver Impregnated Carbon, on the other hand, is bacteriostatic - meaning that it is proven to inhibit the growth of carbon-fed bacteria within the filter to prevent bio-fouling and prolong the life of a cartridge - even while it is not being used! Therefore, when it comes to filtering raw water, Bacteriostatic (Silver Impregnated) Coconut Carbon is the number one choice, as this media is specifically designed for use with rainwater, tanks and bores* to prevent bacteria from breeding and colonising within the carbon and extending the life of your filter. Silver Impregnated Carbon is ideal for periods of time where the filter may go unused. If you want to get the most out of your carbon filter, you can even go one step further and dry it out between uses! 
 

So, how does Silver Impregnation inhibit the growth of bacteria in a carbon filter? When bacteria come into contact with silver, the silver ions puncture the bacteria's cell membrane and wreak havoc by binding to and denaturing the bacteria's DNA. The sulphydryl group already within the bacterial cell also reacts with the silver, producing a silver sulphur complex that immobilises the respiratory and reproductive activity of the bacterial cell. Interestingly, Silver Impregnation has an incredibly long-lasting effect, as the dead bacteria then leach the silver molecules back into their environment, effectively killing neighbouring live bacteria as they die.

Dead bacteria store the microscopic silver particles within their cells (see above image of dead bacteria with silver nanoparticles (white spots), making them deadly to live bacteria.

GT4-19LRC - 0.5 Micron Lead Reduction Composite Coconut Carbon (For Chlorine Reduction & Heavy Metal Concerns in Rainwater, Old Infrastructure, Cities & Industrial Areas)

  • Reduction of Chlorine, Tastes, Odours and Heavy Metals.
  • Ideal for Filtering Tank/Bore Water where atmospheric pollution may be of concern.

Constant exposure to heavy metals combined with the different chemicals being used to treat our water supplies can have serious health effects, and can also cause severe plumbing problems within our homes. Rainwater (acidic pH) and chlorine/chloramine treated water (basic pH) both tend to be quite corrosive, and this can wreak havoc on the internal plumbing and fixtures within old municipalities and even the copper and brass fixtures in your home (which fittings may contain traces of lead)! Rainwater is also commonly contaminated with heavy metals - especially in cities and industrial areas. On this basis, it is also not uncommon to have elevated heavy metal levels in rainwater supplies. 

This cartridge is perfectly suited to reducing trace heavy metals that may be present in your water. The technologically-advanced Lead Reduction Cartridge is impregnated with BASF ATS Lead and Heavy Metals Adsorbent Media, which features a high capacity for the reduction of Lead and other heavy metals such as Arsenic, Chrome, Copper etc., along with the usual benefits of carbon in the reduction of Chlorine, Volatile Organic Compounds, and Trihalomethanes.

GT4-19SMC - 0.5 Micron Surface Modification Coconut Carbon (For Reducing Water Discolouration/Tannin Reduction)

  • Ideal for Reducing Tannin Discolouration, Chlorine, Tastes & Odours in Tank** & Raw Water.

Surface Modification Carbon uses a unique blend of highly reactive catalytic coconut carbon with the highest performance reduction technology. SMC filters are the best type of cartridges to reduce water discolouration, including rust and most tannins. Surface Modification Filters are commonly referred to as ‘Tannin Removal Filters’. Also filters Chlorine. 

A Note on Treating Tannin:
Tannin removal can be a bit hit and miss - usually carbon will remove most of the tannin, but sometimes it doesn’t. Because of this, we normally recommend doing a small scale “litmus test” with a cheap carbon filter to see if this makes a difference to the colour. If it works, then we can be more certain that you will get a good result with a standard carbon filter, and a great result with this 0.5 Micron SMC Tannin Reduction filter! Please contact us before purchasing this filter if you are unsure about the source of colour in your water, so that we can help you with the right recommendation to get the best result!

Whilst many people enjoy the sweet taste of rainwater, we cannot stress enough that drinking raw, untreated water from a tank is a very bad idea! Scarily, in Australia the general public perception is that rainwater is pure, clean, and safe to drink - but according to the Australian Environmental Health committee’s Guidance of the Use of Rainwater tanks, the fact is that the microbial quality of tank-collected rainwater is typically WORSE than regular urban tap water!

The chemical quality of rainwater can be negatively impacted for those living near heavy industry or in areas with heavy traffic emissions. For example, rainwater samples in Port Pirie, South Australia, (which has one of the world’s largest lead smelters), have been found to contain levels of heavy metals such as lead that exceed Australian Drinking Water Guidelines by up to ten times! Even bushfire can contaminate rainwater, in which case you'll need to have your tanks cleaned out!

And that’s not to mention the microbiologically sickening soup of bacteria, viruses & parasites that inevitably make their way into your tank from disease-spreading insects such as mosquitoes, the excrement and decaying carcasses of frogs, snakes, rodents, and possums that commonly live in and around tanks, and the droppings from bats and birds flying overhead! Also consider that bacteria tend to proliferate in moist and warm environments - meaning that warmer weather, in particular, has the tendency to turn your tank into a putrified bacterial breeding ground. E.Coli, Salmonella, Legionella & P. Aeruginosa are some of the more common pathogenic bacteria found in rainwater tanks, whilst Cryptosporidium and Giardia Cysts are the most common rainwater tank parasites. All of these pathogens are a common cause of Gastro!

Thus, whilst rainwater may smell odourless, taste great, and look clean and clear to the naked eye, with the human senses alone, you simply cannot tell what potentially harmful microscopic contaminants could be lurking in your tank water (even after filtering the water with carbon) – and you certainly don’t want to be drinking it!

UV Water Sanitation is by far the most important filtration process when it comes to rainwater treatment. Ultraviolet sanitation works by breaking down the cell wall of micro-organisms (bacteria, parasites, viruses, fungi & yeast), allowing oxidation to occur which in turn prevents the microbe from multiplying until it is finally eradicated. Ultraviolet filtration is a chemical-free solution to water sanitation, creating no by-products in the water, and is recommended by the Australian Drinking Water Guidelines as a safe, effective and chemical-free water disinfection technique:

Installation Requirements

  • This appliance must be installed directly into a single socket surge protector before being connected to a 240V 10A General Power Outlet (Power Point). It must be a surge protector - Circuit Breakers and Residual Current Devices (RCDs) are not suitable substitutes as they do not protect the unit from power surges.
  • The GT7-9K UV System is not weatherproof and all components (including the chamber and electronics) must be shielded from direct sunlight and weather extremes such as rain, storms, and frost. Looking for a fully enclosed Whole House UV System?  Check out the specially designed High Performance | Weatherproof Twin Filter + UV Whole House Water Sanitation System (HPF-UV):

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 the 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 sanitise the water passing through. It is recommended to clean the thimble periodically (every 3-6 months with alcohol or a mild detergent.

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

GT7-9K UV System Replacement Parts:

OPTIONAL (RECOMMENDED) ADD ON: HydroSil Ultra 7.5% | Silver Stabilised Hydrogen Peroxide Water Sanitiser

As UV is a point of use (non-residual) form of water sanitation, we strongly recommend dosing your tank with a product such as Hydrosil Ultra 7.5% Water Sanitiser upon installation of your Whole House UV System, to ensure full protection against bacterial and fungal contamination/biofouling/biofilm build-up in your pipework and/or filter system.

HydroSil is a food-grade silver and hydrogen-peroxide based water sanitiser, which acts to oxidise bacteria and fungi without leaving any dangerous residues behind. HydroSil sanitizes and protects your tanks and filtration devices to help make your tank water safe for human consumption. HydroSil is not a chlorine-based chemical like most sterilizers on the market today. It is non-toxic, and safe to use around your home and family.

Dosage Instructions for the Initial Treatment Immediately Prior to System Installation:

  • HydroSil should be dosed at a rate of 200mL (2L) per 1000L (10KL) of tank water.
  • Turn on every tap in the house until you are satisfied that the treated water has passed through.
  • Immediately install the Whole House System.
  • It is recommended that this dosing procedure should be completed every time the UV lamp is changed.

**FILTERING BORE WATER - IMPORTANT INFORMATION BEFORE YOU ORDER**

About Bore Water

Bore water will always require filtration, as whilst you would think it is “naturally purified” to some extent as the water seeps through the aquifer via various layers of bedrock, this water is highly susceptible to contamination by bacteria, viruses, parasites (see: Brain-Eating Parasites), sewerage (think human excrement, cleaning and bathing products), chemicals, fertilisers, pesticides, minerals, heavy metals (such as lead, zinc, chromium, copper, cadmium, arsenic and nickel), and sometimes even radioactive elements (such as uranium) from both natural sources and human activity. As with rainwater treatment, the most cost-effective solution is typically to use 5 Micron Carbon Filtration in combination with UV Sterilisation to ensure 99.9% eradication of all parasites, bacteria, viruses. However, this system is not always a "total fix", as bore water chemistry is incredibly complex, and sometimes may not even be treatable. Yet another common misconception we often encounter is that carbon can filter out anything and everything – but unfortunately, carbon doesn’t kill bacteria or remove minerals, salts and other such dissolved inorganic substances!

We STRONGLY recommend that you get your bore water tested to determine if there are any underlying issues in the water chemistry of your bore, before you make any purchases or try to filter it. If you have not had your water tested yet and would like to get this done, please contact us to have your bore water analysed.

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.

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 sanitise the water passing through.

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