Step A – Position tank in desired loca-
tion . Stand it upright or lay it
on its side (using the black
plastic stand) . Measure the
blue tube from the RO mod-
ule port marked TANK over to

Check Air Pressure in the Tank
Note: Check air pressure when tank is empty of water!
Check air pressure in the storage tank when you notice a de-
crease 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.
Step A – Turn off the incoming water
supply to the RO by turning the
knob on the Adapt-A-Valve™
clockwise until it stops . (Follow
the green tube away from the
RO system to find the Adapt-A-
Valve™) .
Step B – Open the RO Faucet and allow
water to drain from the tank until it is completely empty .
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.
Step C – Once all water in the tank is
purged, check air pressure
using an air pressure gauge . It
should read between 5 - 7psi .
(Digital air pressure gauge is
recommended)
