Cartridges are very easy to replace and only have to be changed over as required or every 12 months, whichever comes first. 

Due to the filtration of particulate & sediments from the water during use, the flow of water from the filter may reduce over a period of time.

If your cartridge water flow rate slows down it is normally only because the outside of the cartridge has blocked with fine sediments. These sediments do build up and can slow the flow rate over time dependant on the volume of sediments in the water supply used to fill the top tank.

To restore the water flow to its normal level, simply remove the cartridge and follow the backwashing instructions to backwash the cartridge and push sediments back out of the cartridge.

If after backwashing the water flow is still slow, you can also get some 100 grit sandpaper or a new Skotchbrite scour pad & scrub the outside of the cartridge under a flowing tap, ensuring that the open-ended thread does not contact the water to avoid contamination. Scrub harshly as this cartridge is quite thick & can be scrubbed clean many times.

Cleanliness is important, wash your hands before handling the cartridge and take care to ensure that no contamination of the cartridge occurs during cleaning. Use a glove or similar so your hands don't touch the cartridge as much as possible.

NEVER WASH WITH DETERGENTS OR SECOND-HAND SCOURER PADS.

If the filter is left to stand for more than 3 - 4 days without use, it is recommended that one litre of water be allowed to flow through the cartridge to waste before using.
