Frequently Asked Questions

Q. "I just installed a new filter cartridge and my water is cloudy/white?"
A. After you install a new filter you should run it for a few minutes. This should be done for all brands of filter cartridges. Cloudy or white water usually indicates air in the line and this is natural and normal with the replacement of a cartridge. Air will enter in the housing, lines and cartridge. Just run the water for a few (up to 5) minutes and the cloudy conditions will go away (unless you have VERY cold water in which case it is the oxygen in the water that could be making the water look cloudy). It is always a good idea to run the water free flowing for a few minutes after installing any brand or type of new filter cartridge. Also, when you're using drinking-water filter cartridges that contain carbon, it is recommended that you run the faucet tap for at least 20 seconds prior to each use to flush very fine black carbon powder that may be present.
