Long Term RO Storage Procedures (1-3 years):

If you don’t use your RO system for an extended period, there are 2 ways to store the RO depending on whether you need to de-install the system or not.

  1. If the RO remains hooked up to your pipes: During idle period, just turn OFF the feed water (close the needle valve), and close the tank’s valve, let the RO stand as is. When ready to use the RO again, just drain out the old tank of water. Let the tank fill up, drain out the tank again to flush the system. The 3rd tank of water is ready for use. Read more

To replace the Auto-Shut-Off valve on your RO system, please follow steps below:

  1. Turn off the feed water to the RO system. Close the tank’s ball valve. Turn on the RO spigot, lift lever up & lock –> this relieves the pressure in the RO system, making line removal easier.
  2. The ASO valve is mounted on the RO frame. There are 4 ports on the ASO valve, see diagram below. Each port connects to a water line: Two RED lines in ports #1 and #2 (at bottom), two CLEAR lines in ports #3 and #4 (on top).
  3. Take ASO valve out of its bracket.  Please note how the 4 lines are connected to the old ASO, so you can re-connect the lines to the correct ports on the new ASO valve. Read more
