probleM cause solution
1. Low/Slow Production Low Water Pressure Assure a minimum of 40psi incoming water pressure.
Watts sells a booster pump if home water pressure is low.
Make sure water supply is turned on and Adapt-A-Valve™ is
all the way open.
Crimps in tubing Check tubing and straighten or replace as necessary.
Clogged pre-filters Replace pre-filters.
Fouled membrane Replace membrane and flow restrictor.
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 running, unit will not shut off Low water pressure See #1 above
Crimp in supply tube Check tubing and straighten or repair as necessary.
High water pressure Check incoming water pressure to make sure it does not
exceed 80psi. A pressure relief valve may be necessary.
High pressure in Tank Empty storage tank of water. Set tank air pressure between
5-7psi. See page 7.
Low Pressure in Tank Use a Digital Air Gauge for best results. The empty tank pres-
sure should be 5-7psi. See Page 7.
4. Noise / Water from faucet vent hole or noise from in drain
line drain.
Crimp or restriction Check tubing and straighten or repair as necessary.
Straighten all drain lines. Clear blockage. Cut off any excess
tubing.
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 storage tank System starting up Normally it takes 4-6 hours to fill tank. Note: low 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 5-7psi when empty of water.
If below 5psi add air or bleed if above 7psi.
Check only when tank is empty of water. See Page 7.
6. Water leaks from the blue or white filter housing Not properly tightened Tighten the bowl.
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 pres-
sure should be 5-7psi. See Page 7.
