Troubleshooting Guide





Cloudy ice cubes or milky colored water.

- Bad membrane


- Water supply.


- System is still new.

- Use TDS Tester Meter to check membrane.  Replace membrane and sanitize when below 75% rejection.

- High oxygen content.  Tiny frozen bubbles.

- Some refrigerators freeze differently, leaving the ice cube looking cloudy. Let cube dissolve in glass of water. If just air, will float to surface and dissipate.

- This is normal and should clear up in two weeks


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 leaks.

-O ring not sealed properly. - If O-ring is damaged, replace.  If dirty, clean, lubricate with Dow 111 silicone sealant and retighten filter housing sump.   Hand tighten firmly.  Do not use a filter housing wrench to tighten.

Hole on faucet is leaking.

- Clamp slipped on drain saddle preventing proper flow to the drain.

- Drain tube loops or dips creating a backup.

- Restriction in drain tube. Remove gunk or food particles in tube or replace the tube.  Just because you are getting water out of the drain tube does not mean that it is coming out fast enough.  Any backup in the tube will cause the faucet to leak.

- Restriction in drain hole inside the hole on the back of the faucet.
- 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.

- "Fouled" membrane.

- 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.

- Replace RO membrane.


System is continually running.

- Prefilters are partially plugged.  Lowered water pressure prevents the hydraulic shut off valve from actuating.

- 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 prefilters.  To check if if it is the prefilters you can remove them and operate the system without them until it shuts off.  This will confirm that the filters are the problem. 

- 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.


Ice maker not working

- Ball valve to ice line is off.

- Ice maker handle in refrigerator is off.

- Ice maker line frozen.

- Tube to refrigerator is kinked.

- Turn on ball valve, also check for any kinked tubes.

- Pull to down position to turn on.

- Thaw with hair dryer. Make sure you have a full tank of water before turning icemaker on.

- Find kink and replace tube.

No water out of refrigerator door.

- 1 quart reservoir not full.
- Hold down dispenser handle for approximately 2 minutes until water comes out. Make sure RO tank is full.

TDS of RO water (permeate) is the same as the incoming feed water.  Also high pressure and endless supply from RO faucet.

- ASV (auto shut-off valve) is defective - High pressure inlet water bypassing the rubber diaphragms in the ASV and entering the Permeate (RO) water line.


 - Water may be bypassing the Brine Seal - (large rubber ring around the outside of the membrane)

- Replace ASV (auto shut-off valve)

- Remove and reinstall membrane making sure that the Brine Seal is making contact with the inside of the membrane housing wall.  Seal the Brine Seal with Dow 111 silicone sealant.  Clean the inside of the membrane housing wall when the membrane is removed.  Examine membrane housing to see if it has warped.  A membrane's brine seal will slowly form to the contour of a housing that is warping.  So the old membrane might fit while a new membrane will have trouble fitting in a warped housing.  Replace a warped membrane housing.

Makes water slow.

- Normal R.O. process.

- Low water pressure.

- Filters plugged.

- Fouled  membrane.

- Low Tank air pressure

- 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.


Faucet Handle Turns On Hard or Won't Lock On.


- Faucet Needs Adjusted


 Adjusting The Handle Of Standard Style Faucets, Both Air-Gap and Non Air-Gap:

The faucet handle will need some force to pull up and lock on, this is normal. If the faucet is hard to get to lock on, taking too much force, or if it won't lock on at all, you will need to adjust the faucet handle "Tee Bar". Remove the spout and handle and adjust the Tee Bar until the faucet handle just slides on and off. Once the tee bar is adjusted slide the faucet handle back on making sure the Tee Bar stays 90 degrees with the faucet handle.
