Once all water in the tank is purged, check air pressure using an air pressure gauge, it should
read between 5 - 7 PSI. (Digital air pressure gauge is recommended)
Check Air Pressure in the Tank
Important:
Step 3
Check air pressure only when tank is empty of water!
Step 1 Turn off the incoming water supply to the RO by turning the needle
valve on the adapt-a-valve clockwise until it stops. (Follow the green
tube away from the RO system to find the adapt-a-valve.)
Open the RO Faucet and allow water to drain from the tank until
it is completely empty.
Step 2
Check air pressure in the storage tank when you notice a decrease in available water from
the RO system. Air can be added with a bicycle pump using the schrader valve that is located
on the lower side of the tank behind the blue plastic cap.
Tip:
When water from the RO faucet slows to a trickle, with the faucet still in the open position, you
may add air to the tank to purge any left over water, this will ensure that the tank is completely
empty.
Procedure for Extended Non-Use (More than 2 months)
Turn off the water supply by turning the “T” on the adapt-a-valve clockwise until it stops and
open the RO faucet to empty the storage tank (Save a few ounces of RO water). Once the
storage tank is empty, remove the membrane and place it in a sealed plastic bag with the RO
water saved earlier and store in your refrigerator.
For restart, reinstall membrane (See page 13 for membrane installation procedure) and follow
startup procedure on page 10.
Step 4
Follow startup procedure on page 10.
