A single shower typically uses around 10 to 12 litres per minute which is the rated flow of most 10 inch Jumbo cartridges. Although a 10 inch cartridge is commonly used in homes with low use, we do prefer to supply 20 inch jumbo systems where there are 2 showers, or 3 or more people are in the home as the water flow performance is better and the cartridges last longer. With double the cartridge size you can run a shower and turn on another tap and still have high removal and flow capacity from the cartridges.
It is recommended to use a sediment cartridge prior to the carbon cartridge to prevent the carbon cartridge from clogging with dirt, but not as essential if you know your water supply is clean.
We typically recommend using 5 micron Activated Carbon cartridges as they provide good filtration and water flows and will not slow down the water flow as finer 1 and 0.5 micron cartridges will. With a 1 micron sediment cartridge in front of the carbon filter, the carbon filter will stay clean and can work at maximum efficiency to remove the chemicals and chlorine.
Cartridges used
Stage 1 – 1 micron Polyester spun sediment cartridge to remove dirt and sediment
Stage 2 – CTO carbon block cartridge ( + option to upgrade to a KDF cartridge to also reduce metals if desired).
Pressure Limiting Valve
A pressure limiting valve is essential to protect the filter casings from cracking under high pressure. Most newer homes have one fitted but older homes may not. Please either order one with the kit or ensure you plumber checks to see if one is required during installation. The casings are rated to 80 psi or 600 kpa.
Wall Bracket options
Twin and Triple Brackets are supplied as standard made from powder coated steel. Stainless Steel Twin brackets and Powder Coated Aluminum triple brackets for wet outdoor installation are available as an option.
