Troubleshooting
Leaks:
...between cap and bottom of filter housing
Turn off water supply valve and turn on drinking water faucet to
release pressure in system. Remove bottom of housing. Clean O-ring
and O-ring groove (located directly beneath threads of housing).
Lubricate O-ring with silicone grease and replace securely into
groove. Screw bottom of housing onto cap and hand-tighten. DO NOT
OVER-TIGHTEN. Turn on water supply valve and check for leaks.
...on system inlet/outlet connections
Turn off water supply valve and turn on drinking water faucet to
release pressure in system. Remove tubing from fitting (see NOTE
under Step Six: Connecting the Supply Adapter on p.3) and make sure
end of tubing is cut squarely and free of scratches or burrs. Reinsert
tubing into quick-connect fittings, making sure to push securely until
tubing hits a hard stop. Turn on water supply valve and check for
leaks.
...on supply adapter connection
Turn off water supply valve and turn on drinking water faucet to
release pressure in system. Loosen leaking threaded fitting on supply
adapter or pull out leaking tubing from fitting. Inspect to see if plastic
tubing is scratched or supply adapter was properly attached. If tubing
is scratched, cut off 1/2" to 5/8" and reinstall per Step Six: Connecting
the Supply Adapter. Reconnect tubing or tighten compression nut with
fingers, then tighten nut snugly 1/2-turn with wrench. Turn on water
supply valve and check for leaks.
...on faucet/tubing connection
Turn off water supply valve and turn on drinking water faucet to
release pressure in system. Loosen and remove compression nut
fitting on faucet stem. Make sure tubing is inserted firmly into end of
faucet stem, then retighten compression nut with fingers until secure
then tighten 1 turn with a wrench. Turn on water supply valve, then
turn off faucet to check for leaks.
NOTE:
If leaks persist, or if there are other leaks on system, turn off
water supply. Call our technical support department at 800.861.8758.
Low Water Flow
1. Check flow at faucet. The US-1500 system should fill a gallon jug
in approximately 2 minutes. Flow rates will vary with individual
household water pressure.
2. Check filter cartridge installation. Make certain both filter
cartridges are properly oriented in filter housings (See Filter
Cartridge Replacement).
3. Check to be certain that the water supply valve is completely open
(turn handle on valve counter-clockwise as far as it will go).
4. Check flow through empty system. To do this, turn off water supply
valve and turn on drinking water faucet to release pressure in
system. Then remove filter cartridges from housings and screw
housings back onto caps. Turn on faucet to check flow through
empty system. Flow should be about one to two gallons per
minute. If flow is less than 0.4 gallons per minute, call Technical
Support at 800.861.8758.
5. If flow through empty system is adequate, place one filter
cartridge in system at a time and check flow to make sure
cartridge is not clogged. Replace clogged cartridge if necessary.
