Twin Whole House Filter System For Chlorinated Water

This system is a Twin Big Blue filter housings with 1″ Bsp threaded inlet & outlet ports that take standard 20″ x 4.5″ filters, mounted on a Stainless Steel bracket with a plastic housing spanner for undoing the filter sumps.

Stage 1: Washable Pleated Sediment Filter (5 Micron)

The first stage of the system is a 2045PW5  5 micron washable pleated sediment filter which will reduce sediment, rust, algae, sand, silt, fine metal particles etc.

These filters can be taken out and hosed clean and reused, depending on your water quality approximately 3 to 6 times.

Stage 2: Refillable Activated Carbon Filter (5 Micron)

The second stage is a refillable filter cartridge which can be filled with either GAC coconut carbon or ORC Catalytic coconut carbon. 

The filter has sediment filter pads inside for under and on top of the carbon. (Simply unscrew the lid of the carbon cartridge to refill, can be reused a number of times before replacing the empty cartridge)

GAC Coconut Carbon

The GAC coconut carbon will reduce Chemicals, Chlorine, Organic Compounds, Trihalomethanes, Fallout from over spray, Bad Taste and Odours greatly improving your water quality.

ORC Carbon (Catalytic Carbon)

ORC carbon is an enhanced Catalytic carbon which is surface modified give it a higher capacity to remove Chlorine and better Chloramine reduction than standard activated carbon.

Package comes with a filter cartridge filled with carbon and takes 2kg of carbon to refill.

To replace the carbon simply remove the cartridge, unscrew the bottom end cap off and empty out old carbon, wash the cartridge and sediment pads out then refill with new carbon, replace end cap install and flush lines to remove any carbon fines until clear.

As a guide, you should usually change your carbon every 6 months but this can vary with water quality and usage.

Depending on water quality and water usage filters may need to be replaced as required.

Rated at 550Kpa maximum pressure. For protection from high pressures it is recommended to have a pressure limiting valve on your system. We can supply a Pressure Limiting Valve.

The PLV valve will help protect all appliances in the house like dishwashers, washing machines and fridges from excessive water pressure. Available in the product Options.

For a small investment you will be surprised at the difference these filters will make to your water quality.

Installation Tips

For New Installation:

  • Do not install in direct sunlight
  • Mount the system a minimum of 100mm off the ground to allow the removal of filters.
  • Check flow direction which is marked on top of the system.
  • If on Mains Water supply it is recommended to have a PLV (pressure limiting valve) fitted before the system.
  • If you are using a pressure pump to supply the water, a PLV may still be required.
  • After installing make sure to flush the new filters for 5 – 10 litres by opening the first tap after the filter system or use the Sump Flushing method. See flushing instructions below.

Flushing new filters – Twin System Sump Flushing Method

  1. Turn off water supply.
  2. Release pressure from system by either depressing Pressure Relief Button on head (if installed), or opening 1st tap after system.
  3. Undo both filter sumps, remove and discard old filters then clean inside of sumps and lubricate o-rings.
  4. Place new Carbon Filter into sump and install into the Sediment First Stage of your twin filter housing, leaving the second stage empty and without the sump attached.
  5. Place a bucket (minimum 4L capacity) underneath second stage to catch flushed waste water.
  6. Slowly turn on water supply and flush until bucket fills and water runs clear of fines – repeat if necessary.
  7. Turn off water supply again.
  8. Undo freshly flushed carbon filter and insert new sediment filter into first stage and re-insert carbon filter into second stage.
  9. Hand tighten sumps only – do not use Sump Spanner to tighten, use for undoing only.
  10. Slowly turn on water supply again – you may still have some air bubbles, this should disperse within a few hours or days.
  11. Check system for leaks around sump seals and fittings.

You have finished flushing the new filters in your system!

Cleaning and opening the filter system

  1. Turn off the water supply to the system, release the water pressure in the pipes by opening the first tap after the filters and leave it turned on.
  2. Use the housing spanner to undo the sumps, turning from right to left.
  3. Remove the dirty filters and using a bottle brush, clean housing sumps and head, then rinse with clean water.
  4. Using a clean cloth or paper towel, wipe around the o-ring seal and where it seats. Before replacing the o-ring, use a small amount of food grade silicone grease to keep the o-ring supple and to help it seal (vegetable or cooking oil will do the same job – do not use petroleum based lubricants).
  5. Only hand tighten the housing sumps – do not use the spanner – then wipe dry with a clean cloth.

Frequently Asked Questions

How Are ORC and GAC Carbon Different?

Both Granular Activated Carbon (GAC) and Odour Reducing Carbon (ORC Catalytic Carbon) are loose granular carbons. They are both made from crushed coconut shells.

The main difference is that ORC carbon has received additional processing to have more pores on its surface. The addition pores give it:

  • Addition chemical storage capacity
  • Faster removal rates
  • The ability to break down more complex chemicals, like Chloramines (Ammonia + Chlorine)
  • The ability to reduce sulphur dioxide odour more efficiently (which is why it is called “Odour Reducing Carbon”)

We usually recommend ORC carbon whenever sulphur dioxide odour is present or the local water authority is using chloramination. It’s also a better option for when someone in the household has a chemical sensitivity as it offers slightly improved chemical removal rates.  

Is ORC more expensive than GAC?

Yes it is.

ORC usually costs about 35 to 40% more than GAC carbon. However, given the fact carbon is quite cheap and lasts for several months in a residential installation, it’s an insignificant difference.
