Problem: Leak at the feedwater tapping valve.

Tapping valve is not clamped tightly enough.


Tighten the tapping valve clamp screws evenly and

firmly keeping both halves of the bracket parallel. Be sure not
to deform tubing.

Problem: Leak at the drain saddle.

Drain saddle not clamped tightly enough.


Tighten the drain saddle screws evenly and firmly.

Problem: Leak at the fittings threaded connection.

Fitting is improperly taped or not

tightened sufficiently.


Retape the threaded portion with Teflon


tape and

thread it in firmly. Do not over tighten.

Problem: Leak at the fittings push-in connection.

Tubing is defective if there is a tubing misassembly.


Remove the tubing. Squarely cut off 1/4 inch from

the end of the tubing using a sharp razor knife and reinsert it
into the fitting. Make sure that the tubing is pushed in com-
pletely until it seats.

Problem: Leak at the filter cartridge head.

Defective or misaligned O-ring.


Close the feedwater tapping valve and the storage

tank valve. Lift up on the faucet handle and drain the tank a
minimum of 5 minutes. Remove the filter cartridge and check
the condition of the O-rings. If they are misaligned, reseal
them. If they are damaged, replace them.

Problem: The faucet leaks from the spout with the handle

An obstructed or defective valve seat in the faucet



Remove the faucet spout with a twisting/lifting motion

and slide the faucet handle forward over the spout hole to gain
access to the faucet valve. Unscrew the tee-bar and the slotted
bushing to remove the valve. Clean out any obstruction or
replace it with a new valve mechanism if necessary.

Problem: No steady drip from the open faucet after the
tank is drained.

The feedwater tapping valve is not open.

The feedwater tapping valve is not installed properly.

A leak from any product water fitting connection.

The icemaker valve was left open before the start-up
procedure completed.

Air is still trapped in the system.


Open the feedwater tapping valve completely.

Check the feedwater tapping valve installation to
make sure that the needle has pierced the tubing.

Correct the fitting leak as outlined above.

Close the icemaker valve and wait until the faucet drips.

Wait for the air to be purged from the system.

Problem: Water leaks from air gap module opening.

The drain line tubing is looped, kinked, or has a low spot.

The drain line is blocked or the drain hole is not drilled
through completely.

Air is locked in the air gap outlet.

There is excessive RO reject flow.


Trim any excess tubing to obtain a short, "straight-shot" to
the drain.

Check to see that the drain line is clear of any obstruction
and remove the drain saddle fitting to verify that the hole is
drilled through completely.

Blow air into the air gap outlet using a short length of tubing.

Disconnect the red SFC reject tubing from the faucet air
gap inlet tubing and check the reject flow rate. It should
be less than 175 ml/min. If it is greater than 175 ml/min.,
replace the red SFC reject tubing with the new one of
proper length.

Problem: Too little or no reject flow.

Red SFC reject tubing is plugged or defective.

The feedwater tapping valve is not open.

An obstruction in the faucet air gap module.


Replace the SFC reject tubing with one of proper length.

Open the feedwater tapping valve completely.

Remove the air gap module and inspect the internal flow
path. Replace the air gap module if necessary.

Problem: Chlorine or other unpleasant taste/odor is evi-
dent after the initial tank filling.

Residual preservative/sanitizer is still in the water.


Drain and fill the storage tank several times if necessary.

Problem: Noise in the drain (gurgling or
dribbling sound).

The reject water is dripping into the standing water in

the drain trap.


Make sure that the 3/8" black drain tubing from the faucet
air gap module slopes continuously downward to the drain
saddle without any loops or low spots.

Angle the drain piping so that the reject water runs down
the side of the drain pipe.

Change the location of the drain saddle to the horizontal
drain pipe or any alternate vertical drain pipe which is
farther from the trap. Properly plug the original hole.


Make sure the drain saddle is always installed

above (before) the trap.
