system and damage your membrane, so even if you have a UV filter it is recommended that you use
this procedure. We recommend sanitizing during a filter change, that way the old filters can be removed
and thrown away, the system can be sanitized and new filters put in.
Sanitization Procedure:
1. Turn off the feed water supply. This is done by closing either the angle ball valve or the feed water
ball valve. The valve is closed when the handle is at a 90° angle to the tubing (when handle is NOT
parallel to tubing).
2. Open the faucet to allow the tank to empty. This water may be saved if so desired. Leave the faucet
open until no more water comes out.
3. Close the faucet.
4. Pull the system out to where it can be easily worked with. If the system was installed with enough
tubing to do so, simply pull it out to where it can be worked on. If the system does not have enough
tubing, you will need to disconnect the lines to pull it out. (When changing the membrane, it helps to
have a towel handy, as some water may leak out.) Make note of which tube goes where to ensure
the system will be hooked up the same way it was.
5. Remove all filters and the membrane from their housings, leave the inline filter(s) (the post filter, as
well as the DI & pH/Mineral filter if the system has them) in place.
6. Add one capful (2 tsp or 10ml) of 5 ¼% bleach (any household bleach, such as Clorox®, will work) to
each filter housing and the membrane housing.
7. If the system was unhooked, hook it back up now.
8. Open the feed water supply and allow water to fill the housings. Open the tank valve and allow 5 - 10
minutes for water to fill the tank.
9. Open the faucet to allow solution to enter lines. Close the faucet and feed water line when water
begins to come out of the faucet.
10. Let solution stand in system for 15 minutes.
11. Open the feed water line and allow 5 - 10 minutes for water to fill the tank, then open the faucet.
12. Allow water to run through the system for 15 - 20 minutes to flush the lines, closing the faucet at
least once to allow the tank to fill again.
13. Install new filters (the inline filters MUST be replaced as detailed in the filter changing instructions,
since the chlorine will exhaust them).
14. Insert membrane (either the original or a new one) into membrane housing.
15. Ensure housings are tight and all connections are secure.
16. Flush the system as detailed in the filter change instructions to clean out the new filters.
17. Your system is now sanitized and ready to use.
