TROUBLE SHOOTING
Problem Cause Solution
1. Low/Slow Production Low Water Pressure Assure a minimum of 40 psi incoming water pressure.
Watts sells a booster pump if home water pressure is
low. Make sure water supply is turned on and Adapta
Valve is all the way open.
Crimps in tube Check tube and straighten or replace as necessary.
Clogged pre-filters Replace pre-filters.
Fouled membrane Replace membrane.
2. Milky colored Water Air in system Air in the system is a normal occurrence with initial
start up of the RO system. This milky look will
disappear during normal use within 1-2 weeks. If
condition reoccurs after filter change, drain tank 1 to 2
times.
3. Water constantly Low water pressure See #1 Above
running, unit will not
shut off Crimp in supply tube Check tube and straighten or repair as necessary.
High water pressure Check incoming water pressure to make sure it does
not exceed 80 psi. A pressure relief valve may be
necessary.
High pressure in Tank Empty storage tank of water. Set tank air pressure
between 5-7 psi. See previous page.
Low Pressure in Tank Use a Digital Air Gauge for best results. The empty
tank pressure should be 5-7 psi. See page 14.
4. Noise / Water from faucet Crimp or restriction Check tube and straighten or repair as necessary.
vent hole or noise from in drain line Straighten all drain lines. Clear blockage. Cut off any
drain. Excess tube
Drain tube clogged Caused from dishwasher or garbage disposal.
Disconnect the 3/8” black line at the drain, clean the
3/8” black line out with a wire, then reconnect. Blowing
air through the line will not always remove the clog.
5. Small amount of water in System starting up Normally it takes 3-6 hours to fill tank. Note: low
storage tank incoming water pressure and/or temperature can
drastically reduce production rate.
Low water pressure See #1 above.
To much air in tank Tank air pressure should be 5-7 psi when empty of water.
If below 5 psi add air or bleed if above 7 psi.
Check only when tank is empty of water.
See previous page.
6. Water leaks from the blue Not properly tightened Tighten the bowl.
or white filter housing Kinked O-ring Turn off the water supply and release the pressure.
Replace the O-ring if necessary. Then lubricate it and
make sure the O-ring is seated in the filter bowl
properly before reinstalling the filter bowl.
7. Low water flow from faucet Check air pressure in tank Use a Digital Air Gauge for best results. The empty
tank pressure should be 5-7 psi. See page 14.
