16. Installation Troubleshooting
Problem:
Water leaks from opening in air gap module.
Possible Causes:
A) Drain line blocked or drain not drilled through completely.
B) Air lock in air gap outlet.
C) Drain line has loop or is not vertical enough.
Solutions:
A) Check that drain line is clear of obstructions and remove drain saddle fi tting to verify that the hole is
drilled through completely.
B) Blow air into air gap outlet using short length of tubing.
C) Shorten tubing so that run is as vertical as possible.
Problem:
Noise in drain (“gurgling” or “dripping” sound)
Possible Cause:
Reject water dripping into standing water in the drain trap.
Solutions:
A) Make sure the 3/8” black tubing from faucet air gap module slopes continuously downward to drain
saddle without loops or low spots.
B) Angle drain piping so reject water runs down side of drainpipe.
C) Change location of drain saddle to horizontal drain pipe or alternate vertical drain pipe farther from the
trap. Properly plug original hole. CAUTION: Make sure drain saddle is always installed above (before)
the trap.
Problem:
System is not producing water.
Possible Cause:
A) Need a minimum of 30 psi (207 kPa) incoming water pressure.
B) Too little or no reject water.
C) Incorrect tank pressure.
Solutions:
A) Increase pressure by adding pressure pump.
B) Disconnect special SFC reject tubing from faucet air gap inlet tubing and check reject fl ow rate which
should be approximately 175 ml/min.
C) Empty water from tank. Lift tank to verify that it is empty. Adjust pressure to 5-7 psi (34-48 kPa).
Problem:
System is not producing enough water.
Possible Cause:
Incorrect tank pressure.
Solutions:
Empty water from tank. Lift tank to verify that it is empty. Adjust pressure to 5-7 psi (34-48 kPa).
