1. If the water source is suspected to carry much physical dirt or sediment, it is recommended to
install a pre filter prior to the carbon cartridge ( as shown above ) to enhance the life of the carbon cartridge. Otherwise dirt may clog the cartridge before the media has been used completely.
2. The pressure loss through the filter at normal flow rates is usually less than 5 PSI ( 35 KPA ) so
most households will not notice any significant pressure reduction until the pre-filter cartridge blocks up.
3. Cartridges for the small house option are typically replaced between 10 to 12 months
depending on the amount of use and quality of the source water.
4. Cartridges are replaced when either bad taste and odour is noted or the water flow slows down
due to the cartridge blocking up with sediment.
Note: Maximum flow rate refers to the maximum recommended speed through the filter for the water to be purified well. It does NOT mean the water is physically restricted to this speed.
