Troubleshooting
Trouble
Possible Issue
Possible Solution
No output water
from the RO
faucet
a. Water supply is turned off.
b. Incorrect installation.
c. Crimped tubing impedes the
water flow.
a. Turn on the water supply.
b. Verify all tubing connections.
c. Check and uncrimp all tubings.
Tank not filling
after several hours
a. Incoming water pressure is
below 45 psi.
b. Incorrect installation.
c. Tank valve (ABV2K) is
closed.
a. Increase the incoming water pressure,
such as adding a booster pump.
b. Verify all tubing connections.
c. Make sure the ABV2K is on.
Leakage in
connections
a. Tubing is not inserted
properly into the port.
b. The O-ring inside the fitting
is not creating a seal.
c. Not applied enough
Plumber's tape to the tank
threads.
d. The housing/cap is not
tightened properly or
misaligned with the threads.
a. Reinsert the tubing about 1/2'' into the
port.
b. Check the O-ring. Replace it if
necessary.
c. Reapply at least 8-10 wraps of
Plumber's tape to ensure a proper seal.
d. Retighten the housing/cap properly.
Low water flow
(trickle) from RO
faucet
a. Tank has not been given
enough time to fill.
b. Incoming water pressure is
below 45 psi.
a. Allow approximately two hours for
the tank to fill.
b. Increase the incoming water pressure,
such as adding a booster pump.
High TDS in RO
water
a. Incorrect installation.
a. Verify all tubing connections and the
direction of filter installation. Contact
the iSpring Customer Service Team if
the trouble still exists.
The system has a
continuous drain
a. Incoming water pressure is
below 45 psi, so the stank can
not be fully filled to shut off
the system.
b. The Automatic Shut-Off
Valve (AAS2) or check valve
is defective.
a. Increase the incoming water pressure,
such as adding a booster pump.
b. See the Steps below for details.
Contact the iSpring Customer Service
Team for replacement.
UV light is not on
when water flows
through
a. No power inlet.
a. Check the power source.
Steps to test if AAS2 or check valve is the cause of the continuous drain:
a. Fill some water from the RO unit to ensure the drain water is flowing.
b. Close the valve on top of the tank.
c. Wait approximately five minutes, then check if the drain tubing is still flowing.
d. If not, both are in good working condition. The ASOV or check valve is defective if it is still
flowing. Turn on the system and allow the tank to fill. Tilt the tank to check the weight and ensure
it is filled at least partially. Then turn off the feed water adapter. With the tank valve open, leave
the system still for 15-30 minutes. If the tank is emptied, the check valve is defective.
