Taste of chlorine in filtered water.	The level of chlorination in your water supply is unusually high.	None.
	The filter cartridge is exhausted and needs replacing.	Replace filter cartridge.
	The cold filtered water is mixed with unfiltered cold water.	Flush the tap for longer before use.
Filtered water tastes metallic.	The filter is correctly removing the taste of the chlorine from the water, chlorine usually masks any such naturally occurring tastes in the water.	Flush the tap for longer before use, if the taste persists it is most likely as described.
Water is cloudy.	Air in the water.	You can check for air in the water by dispensing 2 glasses of water, one filtered and one normal cold water. In both cases it is normal for the water to be cloudy at first, before settling after approx. 10 minutes. However, if the cause is air then the glass will normally clear from the bottom upwards as the air rises."
	Chalk deposits in water.	In some water regions, cloudiness can also be attributed to chalk in the water. We recommend conducting the same test as above (air). However, this can take up to 1 hour to clear and in this case will clear from the top of the glass downwards as the debris settles.
	Loose carbon fines in the water .	Flush the tap for longer before use.
Acidic taste.	If the boiler has been descaled recently, some concentration of the descaling solution may remain in the tank.	Follow the section "draining the boiler" to drain and refill the boiler. Repeat until the taste dissipates.
Acidic taste.	The bypass setting on the filter head may have been set correctly.	Refer to installation section "filter installation" and check the filter head bypass setting.
TCP / disinfectant taste.	Plastic or rubber components in the water supply reacting with chlorine.	Check that any additional plumbing work locally to the new mixer tap uses only WRAS approved materials.
