SANITIZING THE DRINKING WATER SYSTEMS
Sanitizing is recommended at least once every year or if water smells (or tastes) bad even after a post carbon
filter replacement. A convenient time for sanitization is during a filter change-out. IT IS IMPORTANT THAT YOU
HAVE CLEAN HANDS WHILE HANDLING INNER PARTS OF THE SYSTEM.
1. Be sure water supply to the RO system is turned off, and the dispenser faucet is open. This will completely
drain the pressure tank.
2. Remove the post carbon filter and the remineralization filter from the system.
3. Put 1.5 - 2.0 oz. of household bleach in the right filter housing and fill it half-way with tap water.
4. Next, close the dispenser faucet (put lever in DOWN position).
5. Open the feed supply valve.
6. Allow 10 minutes for the bleach solution to flow through the system and into the storage tank.
7. Open dispenser faucet and keep the lever in the UP position till some bleach solution is dispensed through
the faucet. IMMEDIATELY close the faucet as soon as the bleach solution is detected. This will sterilize the
faucet and the line going to the faucet.
8. Let the system sit for 2 hours.
9. Open the dispenser faucet to drain bleach solution from the pressure tank as completely as possible and
then close the faucet.
10. Allow the tank to fill until pressure gauge reaches at least 40 psi. Then open the dispenser faucet and flush
system until all bleach solution has been dispensed from the system.
11. Close the feed supply valve.
12. Remove post-filter housings from the system and then rinse them with tap water and drain completely.
13. Install new post-carbon and remineralization filters and hand tighten the housings.
14. Open the feed supply valve and check for leaks. This completes the procedure.
NOTE: Do not use filter wrench to tighten housings. Over-tightening will damage housings and void
your warranty.
