PROBLEM
CAUSE
SOLUTION
Noisy drain or faucet

- Air gap faucet.

- Drain tube.

- A little noise is common with air gap faucets. Check manual to be sure installed in proper location. Allow two weeks for air to work out of system.

Check that drain tube from faucet is continuously down hill to drain saddle. Loops or dips will cause noise and back up in drain line to faucet.
Filter housing sump leak
-Oring not sealed properly
- If O-ring is damaged, replace and retighten filter housing sump.   Do not use a filter housing wrench to tighten.
Hole on faucet is leaking

- Clamp slipped on drain saddle.
- Drain tube loops or dips.

- Restriction in drain tube.

- Restriction in faucet holes.

- Align hole in drain saddle with hole in drain pipe.
- Shorten drain tube form faucet until smooth down hill flow to drain saddle.
- Disconnect drain tube and clean out restriction. (Food particles from garbage disposal).

- The drain hole in the base and on the rear of the faucet must both be clear and unrestricted.  Clean as necessary
Water does not taste or smell right

- Bad membrane.
-Filters have expired.
- Little water use.

- System needs sanitizing.

- Test membrane with a TDS tester meter.  Replace RO membrane when below 75% rejection and sanitize.
- Replace water filters. Should be replaced every 6 to 12 months.
- Drain entire tank. Should be done once every week to keep stored water fresh.

- Sanitize (see Sanitizing Instructions) and replace filters.
Little water from faucet

- Over pressurized tank.
- Incoming water pressure is below 40 PSI.
- Tank valve not open.
- Bad water storage tank.
- Filters clogged.

- Kinked tube

- Check pressure with specially calibrated air pressure gauge.  When empty, tank pressure should be 7 PSI.
- Increase pressure to 40 PSI.  May require a pump.
- System takes 6 to 10 hours to completely fill.
- Open tank valve.
- Replace storage tank, If not bad, check that tank air pressure is between 7 PSI when empty.
- Replace water filters.

- Un-kink tube. If damaged, replace tube.
System is continually running

- Auto-shut off valve not working.
- Low incoming water pressure.
- Low tank air pressure.
- Tank bladder is ruptured.  Is the tank heavy after draining out all water?
- Flow restrictor worn out.

Membrane is bad (fouled).

- Replace auto shut off valve.
- Increase incoming water pressure to 40 PSI or better.  This may take a pump.
- Check tank pressure with specially calibrated air pressure gauge.  Fill to 7 PSI.
- Replace the tank.
- Replace the flow restrictor.

- Use TDS tester meter to check membrane.  Replace membrane.
Makes water slow

- Normal R.O. process.
- Low water pressure.
- Filters plugged.

- Fouled membrane.

- Your RO system makes water a drop at a time. 4 gallon storage tank should be full within 6 hours.
- Increase incoming water pressure. This may require a pump.  Check for kinked tubes.
- Replace water filters.
- Replace RO membrane.
- Check tank pressure with specially calibrated air pressure gauge.  Fill to 7 PSI.
