N. INSTALLATION TROUBLESHOOTING
Problem: Leak at the drain saddle.
Possible Cause: Drain saddle not clamped tightly enough.
Solution: Tighten the drain saddle screws evenly and firmly.
Problem: Leak at the fittings threaded connection.
Possible Cause: Fitting is improperly taped or not tightened sufficiently.
Solution: Re tape the threaded portion with PTFE tape and thread it in
firmly. Do not over tighten.
Problem: Leak at the fittings push-in connection.
Possible Cause: Tubing is damaged if there is a tubing misassembly.
Solution: 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 completely until it seats. Refer to
"Using Push-In Fittings" Section on page 7.
Problem: Leak at the replacement filter head.
Possible Cause: Damaged or misaligned O-ring.
Solution: Close the cold water feed valve and the storage tank valve
and unplug the booster pump transformer. Lift up on the faucet handle
and drain the system a minimum of five (5) minutes. Remove the
replacement filter where leak is found. Ensure both o-rings are present
on the replacement filter and are seated into grooves; moisten o-rings
with water. DO NOT use any petroleum products to lubricate the
o-rings. Open the cold water feed valve and the storage tank valve and
plug in the booster pump transformer. Re-check for leak.
Problem: The faucet leaks from the spout with the handle down.
Possible Cause: An obstructed or damaged valve seat in the faucet
mechanism.
Solution: Call Customer Care team at 855-3M-WATER (855-369-2837)
for assistance in attempt to repair.
Problem: No steady drip from the open faucet after the tank is drained.
Possible Causes:
The cold water feed valve is not open.
•
A leak from any product water fitting connection.
•
Air is still trapped in the system.
•
Solutions:
Open the cold water feed valve completely.
•
Correct the fitting leak as outlined above.
•
Wait for the air to be purged from the system.
•
Problem: Water leaks from air gap module opening.
Possible Causes:
The drain line is blocked or the drain hole is not drilled through
•
completely.
The drain line has a loop in it.
•
Air is locked in the air gap outlet.
•
There is excessive RO reject flow.
•
Solutions:
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.
Shorten tubing so that it is as vertical as possible.
•
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 5.9
ounces/min. If it is greater than 5.9 ounces/min., replace the red SFC
reject tubing with the new one of proper length.
Problem: Too little or no reject flow.
Possible Causes:
Red SFC reject tubing is plugged or damaged.
•
The cold water feed valve is not open.
•
Solutions:
Replace the SFC reject tubing with one of proper length.
•
Open the cold water feed valve completely.
•
Problem: Chlorine or other unpleasant taste/odor is evident after the
initial tank filling.
Possible Cause: Residual sanitizer is still in the water.
Solution: Drain and fill the storage tank several times if necessary.
Problem: Noise in the drain (gurgling or dribbling sound).
Possible Cause: The reject water is dripping into the standing water in the
drain trap.
Solutions:
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. Caution: Make sure the drain
saddle is always installed above (before) the trap.
Drill larger hole in drain pipe.
•
Problem: Little or no water available.
Possible Cause:
•
Booster pump transformer is not plugged into a non-switched
110V, 60Hz power source.
Tank has not had time to fill.
•
Tank has little or no air charge.
•
•
Pro RO membrane module output significantly below normal.
Solutions:
Wait. The tank will take approximately 4 hours to fill.
•
An empty tank with the ball valve open to atmosphere, should have
•
a 7-8 psi air charge.
Contact our Customer Care Team at 855-3M-WATER (855-369-
•
2837) for instructions.
