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.
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 previous page.
6. Water leaks from the filter membrane housing Not properly tightened Re-insert the filter / membrane housing.
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 5-7 psi. To reset the air pressure in the tank,
turn off water supply and drain tank by opening faucet. When
water stops flowing out of the faucet. Remove schrader valve
cover pump air into tank until water stops flowing from the
faucet. Release the air out of the schrader valve until you
reach 5-7 psi. Replace schrader valve cover. Turn on Water.
