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.

How to change the MB051 water filter

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.
