    Double Stage Home Water Filtration


    The Double Stage Home Water Filtration is a simple and inexpensive way of removing unwanted particles from a water supply. 

    Depending on the Filter Set You Select on the Double Stage Big Blue System, the system may also remove chlorine, heavy metals, and some bacteria from the source water. 

    This option comes with the housings, Filters, and Brackets (Optional) loose. The fittings and connections between the housings are not provided, and so will have to be sourced separately.



    • All the water supplied to your house is filtered
    • Removes chemicals such as chlorine
    • Filtrated water tastes and smells great
    • Preserve the natural minerals in the water
    • No water wasted during filtration
    • Low maintenance
    • Relatively low filter replacement cost
    • No electricity required
    • Large filtration capacity
    • Low-cost filtration solution


    Keep in mind:


    • These systems are not ideal for situations with heavy bacteria levels. while the 1 Micron and 0.2 Micron Filters will capture some bacteria, we would recommend that you would rather want to consider a more advanced filtration system, such as the Complete Home Ultra Filtration (UF) Systems or Complete Home Ultra Violet (UV) Systems.
    • Minerals and pesticides are too small to be removed by the filters in this filtration unit.
    • You will require some plumbing knowledge and experience to install the system successfully.
    • These systems typically filter water at a peak flow rate of 2400 liters per hour.
    • The Filter housings have a maximum operating pressure of 90 psi. If you suspect that your water pressure will at any time exceed 80 psi, a pressure regulator MUST BE INSTALLED before the filter housing. This action will guard against the water pressure exceeding the maximum pressure rating. It is recommended that the pressure regulator is set at 70 psi or less.
    • Protect the filter housing from freezing, as this can cause the housing to crack. 


    Installation of the Double Stage Big Blue System 

    • Approximate Dimensions of each 20 Inch Big Blue Housing (excluding the housing bracket) is 60cm x 19cm x 19cm.

    Additional Options 


    Arkal Disc Filter


    The Disc filter would be installed before the complete home big blue system.  

    The disc filter will remove any large sediment, dirt, rust, sand and other large visible particles in the water.

    The disc filter will also help to extend the lifespan of your finer particle filters, by leaving only the smaller particles and colors for the Sediment Filters to remove.

    The disc filter’s cartridge is reusable, and once it becomes filled you simply open the housing, remove the cartridge, wash it under a tap and then replace it in the housing.

    The Disc Filter is available in the following options: 

    - 1 Inch Disc Filter (55 Micron)

    - 1 Inch Super Disc Filter (55 Micron)

    - 2 Inch Disc Filter (20 Micron)

    * The main difference between the three options is the surface areas, with the 1 Inch Disc Filter having the smallest and the 2 Inch Disc Filter having the largest. This simply means that the 2 Inch Disc Filter would need to be cleaned less often than the 1 Inch units. 

    The 2 Inch Disc Filter also filters to a finer level, than the 1-inch Units. 


    Single O-ring or Double O-ring housing

    The Big Blue Housings are available with either a single O-ring seal or two o-ring seals between the housing base and lid. 

    While both types of housings are rated for the same pressure (6 bar), the additional O-ring seal simply gives additional peace of mind against leakage from the housing. 



    Wall Mounting Bracket  

    The Wall mounting bracket will allow you to mount the Big Blue Housing against a wall or surface. 

    The Wall Mounting Bracket is available in either powder coated Mild Steel or Stainless Steel. 

    However, when installed outdoors especially coastal regions the powder coated mild steel brackets can rust and perish. 

    There is an option of upgrading the frame to Stainless Steel, which will not rust.

    We would especially recommend this option for those clients living at the coast (like in Cape Town, or Durban, Etc). 

    Please note that the stainless steel brackets are typically built to order, if there is none in stock then new ones will need to be made. Lead time is typically 1 week, depending on the availability of Stainless Steel. 

    PVC Threaded and Glue Fittings

    PVC(Polyvinyl chloride) fittings are used to connect sections of pipes or tubes, adapt to different sizes or shapes, and controlling the flow of water. There are two predominant types of PVC fittings namely PVC Glue Fittings and PVC Threaded Fittings. The difference between the two is that PVC Glue Fittings result in permanent joints and PVC Threaded Fittings are semi-permanent and can be replaced. PVC Glue fittings are joined with primer and cement- a chemical solvent that melts the surface of the PVC and then quickly re-hardens to fuse the pieces together. This results in an airtight, leak-proof bond similar to what you get with welding metal. An example of such a fitting is a PVC Glue Reducing Socket which is used to join together two pieces of PVC pipes with different diameters. Another example would be a  90 Degree Elbow which is used to connect two pipes of the same diameter at an angle of 90 degrees.PVC Threaded fittings utilise a simple threaded connection whereby replaceable 'male threaded' are screwed into 'female threaded'.Male threads have a thread on the outside of the fitting and female threads have a thread on the inside. When you thread the fitting in, it compresses against the other threads.PTFE tape is used to thread these together and the proper way to assemble threaded fittings is to finger tighten, then add one to two turns but no more. An example of a threaded fitting is a Reducing Nipple Male Threaded which is used to connect between two female threads of different diameters.
