Rainwater can contain harmful bacteria which is why rainwater tank filters are a necessity for the protection of your family and your home.
At The Tank Doctor we only sell the very best quality rainwater filter systems available on the market that include excellent warranty. Designed and built in Australia, Filtatank Systems utilise quality made patented filter housings that are made in Italy; and Viqua ultraviolet sterilisation systems made in Canada; you are guaranteed the safety of your family’s health is in the very best hands.
A Filtatank Rainwater Filter System is the best investment you will make in the protection and wellbeing for you, your family and your home.
Throughout this section, we explain detailed information and the many benefits about Filtatank Rainwater Filtration Systems
Continue scrolling to discover informative details and benefits of Rainwater Filtration or click the images below to jump directly to each topic; download our brochure to browse at your leisure or go direct to view system information and pricing.
Our filtration systems are large in size with 25mm (1″) pipework and water ports so you will not notice any loss of flow or pressure with the system in operation. Only in time when the filter cartridges become overwhelmed with sediment will a loss of flow or pressure be noticed.
Rainwater tank filters are an important investment for the protection of your family and your home. Rainwater can contain harmful bacteria such as E-Coli, giardia, Salmonella, Campylobacter and cryptosporidium which can easily be transferred through animal faecal matter from birds, possums and vermin that may come into contact with the rainwater supply.
The young, the elderly, and those with compromised immune systems are among the most susceptible to infection because their intestines are less resilient to the effects of bacteria. Water tank filtration systems with ultraviolet sterilisation offer a safe, chemical-free solution to keep these vulnerable individuals safe from harmful microorganisms that may be present in the rainwater supply.
People often neglect their rainwater tanks and water tank filters by mistake. Life is just so busy, especially with young families.
Things that you can’t see often get overlooked and forgotten about. That is why installation of a Rainwater Filtration System with Ultraviolet Sterilisation creates a permanent safety barrier and is such an important investment for the protection of your family’s health.

Neglected tanks can become polluted with leaves, pollen, slime and sludge from wet systems. The water becomes a broth and has a strong smell of ‘rotten egg gas’ or sulfur dioxide.

Rusty old tanks create unwanted taste to the water and should be replaced. Rusty holes in the roof can allow vermin to drown in the tank adding to the risk of dangerous bacteria levels.

Holes in a tank roof, water inlet pipes and manhole covers left open will allow access for possums, vermin and even cats seeking water. Once inside they drown, decay and heavily pollute the water.

Testing can be performed to detect bacteria such as E.coli, cryptosporidium and giardia. With varying rainwater conditions throughout the year, filtration with UV sterilisation is a safe option.
Filtatank Systems are proudly designed and built in Australia from high quality stainless steel and superior components. Each system is hand built and assembled in Australia by the team at The Tank Doctor.
Filtatank Rainwater Filtration Systems protect the health of your family by filtering and sterilising your rainwater before it enters the house. They protect from dirt particles and organic matter which cause discolouration, taste and odour to the water supply and contribute to corrosion and blockages of household appliances such as the dishwasher, washing machine and hot water service.
The First Stage of Rainwater Filtration is achieved through a Twin or Triple Cartridge 20″ x 4.5″ rainwater filter system. Dirt particles, colour, and taste will be captured by filter cartridges. These systems have a large surface area meaning there is no noticeable restriction to flow or pressure of the water supply. On average, filter cartridge changes can be performed on an annual basis with this size of filter cartridge.
The difference between the Filtatank twin and triple cartridge filtration system is the addition of a 5-micron poly-spun filter cartridge in stage two of the triple system. This cartridge is designed to capture finer particles following the 10-micron pleated first stage cartridge. This will protect the silver carbon cartridge which is only designed to absorb colour, taste and odour and doesn’t do well if receiving a lot of dirt particles.
The twin system is ideal for the standard size family home with decent quality rainwater. If the water is quite dirty and brown in colour and there is a high demand on the filter system then we recommend installing the triple cartridge filter system.
After Stage One has removed the dirt and sediment particles, sterilisation of the rainwater supply is achieved through a high quality Ultraviolet Sterilisation system before it enters the house.
It is very important that a high quality UV system is installed because not all UV systems are the same. VIQUA is proud to be the world’s largest supplier of residential and light commercial UV water disinfection systems, providing safe water without the use of chemicals. Viqua has more than 40 years of experience in the residential UV business.
The amount of sludge that is captured by the Rainwater Filt amount of sludgeer Cartridges in just 12-months is quite shocking.
Ultraviolet water sterilisation systems are an effective and economical way of eliminating 99.9% of harmful bacteria form the rainwater supply. The water is exposed to Ultraviolet light as it passes through the stainless steel UV chamber. This process exposes any harmful bacteria to ultraviolet light at a wavelength of 254nm. The UV light penetrates the cell walls of harmful, illness-causing microorganisms by attacking their DNA which eliminates their ability to reproduce.

When it comes to rainwater tanks, David is a really knowledgeable bloke who knows his stuff. Super friendly service and follow up. I’ve invested in a filtration system expertly installed by David & his team and the replacement cartridges are always delivered promptly on time when ordered. Our rainwater went from stinky beer coloured to crystal clear once Tank Doctor had sorted my system. Would highly recommend this business and David to any prospective customer.

Twin filter cartridges remove unwanted sediment through a 10-micron polyester pleated cartridge followed by a 5-micron silver impregnated carbon cartridge to remove colour, taste and odour. Silver is used to inhibit the growth of bacteria on the cartridge. Pressure gauges indicate water inlet and outlet pressure.
Microban® antimicrobial product protection is a built-in biocide silver that enables the filter housings to resist the growth of microbes such as bacteria, mould and mildew. By creating an inhospitable environment this disrupts the metabolism of contaminating microbes by preventing conversion of nutrients into energy. This inhibits microbial survival, reproduction and colonization and disrupts vital cell functions of the microbe.
Water filtrations systems incorporating Microban® protection ensure filter housings stay cleaner, last longer and stay fresher in between cleanings than products with untreated surfaces. This sets Microban® antimicrobials apart from many other competitor products in the market today.
Triple 20″ x 4.5″ Whole House Rainwater Filter Systems remove unwanted sediment through a 10-micron polyester pleated cartridge, followed by a 5-micron poly spun cartridge to remove finer silt particles before filtering through a 5-micron silver impregnated carbon cartridge to remove colour, taste and odour. Silver is used to inhibit the growth of bacteria on the cartridge. The spun cartridge helps extend the workable life of the carbon cartridge. Pressure gauges indicate water inlet and outlet pressure.
