How to change the water filter in your Puretec SIB1
Watch the guide or follow the steps.
No clear video for this part yet. The steps cover it.
- 1Close the ball valve to stop the water, then open the filtered tap to let the pressure out.
- 2Put a container underneath and unscrew the housing bowl with the spanner. Throw the old cartridge away.
- 3Wash the inside of the bowl with warm soapy water. Check the O-ring, grease it lightly with food-grade silicone and replace it if it is kinked or damaged.
- 4Put the new cartridge in and screw the bowl back on hand tight. On twin units the sediment cartridge goes on the inlet side and the carbon cartridge on the outlet side.
- 5Open the ball valve, check for leaks and run the tap for about 10 minutes. Milky water is just air and clears.

Common questions
- Which water filter fits the Puretec SIB1?
- The Puretec SIB1 takes the Puretec EC951 extruded carbon cartridge (0.5 micron, 10 inch).
- How often should I replace the water filter in my Puretec SIB1?
- Every 6 months. Flow slows and performance drops off as the filter fills up, so it's worth doing on time.
- Where can I buy the EC951 in Australia?
- We track 1 Australian seller for the EC951; the lowest listed price when we last checked was A$36.00 at eBay AU. Prices are re-checked daily and dated on this page.
- How do I fit the EC951 in a Puretec SIB1?
- 5 steps, listed on this page with the replacement video where the maker has one.
- What happens if I don't change it?
- The carbon stops reducing chlorine taste and odour and the flow from the tap slows as the cartridge clogs; a boiling-water tap with a scale-reducing filter builds scale in its tank faster.
- Is there anything to reset afterwards?
- No reset light. Write the date on the housing.
