Sediment Filtration System

Post-Tank Rainwater Filters
Filter fine sediments, colours and odours for use around your property with this all-in-one filter cartridge.
Size 5" WFRW05

Get heavy duty filtering

With UV-resistant components, corrosion-resistant fittings, a higher dirt loading capacity and 7+ times more surface area than traditional carbon filters, the Triple Action Filtration System offers heavy duty filtration and is equipped to handle full flow rates and high water volumes.

 

Filter fine particles

The filter’s cartridges remove fine sediments down to 15 microns. This helps to protect your appliances and gives you fit-for-purpose water for your toilets, laundry, dishwasher, irrigation and hot water system. (Please note that this filtering is not sufficient for potable water.)

 

Filter colours and odours

The Triple Action Filtration System reduces water odours and discolouration to offer addition protection for your appliances. The filter cartridges are also resistant to bacterial attack so you can enjoy greater confidence in your water quality.

Benefits of Post-Tank Filters

The Triple Action Filtration System offers heavy duty filtration and is equipped to handle full flow rates and high water volumes. The filter’s cartridges remove fine sediments and this helps to protect your appliances and gives you fit-for-purpose water meaning the triple Action Filtration System Provides a Safety Net to water odours and discolouration.

The Rain Harvesting steps addressed:

Limit sources of contamination     Plan for volume

Filter leaves and debris                    Divert the first flush

Secure the system                             Manage standing water

Consider a safety net                        Monitor and maintain

  • Installation

    NOTE 1: Existing state and local plumbing codes may require installation of this filtration system to be installed by a licenced contractor.

    NOTE 2: Installation of the Filtration system should be located downstream of an available isolation valve. If you do not have one, it is recommended to install now to accommodate ease of any future filtration cartridge service and maintenance.

    NOTE 3: Your Filtration system has a working pressure rated to a maximum of 800kpa (116psi) . It is recommended to test your supply working pressure prior to installation and install an appropriate pressure limiting device if your supply pressure could exceed the above limit.

    Installation

    1. Select an installation point for your Triple Action Filtration System. This must be after both your rainwater tank pump and any mains/rainwater diversion devices. Ensure that the location you choose will allow enough room below your filtration system unit to enable the unit to be dismantled and the filter cartridge to be replaced. We recommend installing the unit horizontally.
    2. If installing outside, we recommend also installing a suitable sunlight protective cover to prolong the life of the filtration housing. Alternatively, you could install your Triple Action Filtration System in a sheltered position.
    3. Using a screw driver and supplied screws, fit the mounting bracket to the top of the filter housing. Ensure you orientate the bracket and inlet/outlet of housing to correspond with the direction of flow in your install location.
    4. Using PTFE tape (Teflon thread tape), install the appropriate threaded adaptors into each end (inlet & outlet) of your filter housing. Take care to not “cross thread” the threaded filter housing. Threaded adaptors may vary depending on the type and size of supply piping you have though we recommend using a “barrel” type union for easy installation.
    5. Mark are remove the section of piping you need to remove by measuring the gap between the unions when pipes are fully inserted.
    6. Cut and deburr both upstream and downstream ends of the piping.
    7. Fit the filter housing in place between the open pipes and secure mounting bracket in place with appropriate anchors. You may find it easier to remove the long housing base and cartridge while performing this step.
    8. Insert the cartridge into the centre of the long housing base ensuring that the O-ring sits cleanly on the O-ring seat and attach this to the housing top by turning anti-clockwise. Tighten fully with the supplied housing ring spanner.
    9. Slowly open the water supply isolation valve and bleed any trapped air from the housing through the pressure relief valve (button or screw on top of the unit), until only water is released. This may need to be performed a few times to allow all air to escape.
    10. Open all down stream taps or valves (one at a time) to purge any remaining air from your system.
  • Maintenance

    The life of your filter cartridge will be determined by three factors: water pressure, water quality and usage. Residual sediments and other matter will eventually build up in your filter cartridge, causing water pressure drops. As such, cartridge life may vary between six and twelve months, subject to these conditions.

    Cartridge replacement is a fairly straightforward maintenance task.

    Before replacing the cartridge in your Triple Action Filtration System, ensure that the water supply, power to the pump and any diversion switches are turned off.

    Release any pressure build up within the housing by using a screwdriver to activate the pressure relief valve on top of the filter housing. Using the housing ring spanner that came with your filter, place the long housing base through the opening and raise the spanner until the ring is secure around the long housing base.

    Unscrew the long housing base with the wrench in a clockwise direction, then remove the used filter cartridge and clean the inside of both upper and lower housings. Be careful not to damage the black O-ring.

    Unwrap the new cartridge and insert it into the long housing base. Ensure that the O-ring sits cleanly on the O-ring seat. Attach this to the housing top by turning anti-clockwise.

    Tighten fully with the supplied housing ring spanner. Slowly open the water supply isolation valve and bleed any trapped air from the housing through the pressure relief valve (button or screw on top of the unit), until only water is released. This may need to be performed a few times to allow all air to escape.

    Open all downstream taps or valves (one at a time) to purge any remaining air from your system.

    Check for any leaks in the system. Seal or otherwise rectify these leaks if required.
