Troubleshooting the System
Problem:
Leaks between cap and bottom of filter housing
Correction:
Turn off water supply and turn on drinking water faucet to release pressure in
system. Remove bottom of housing. Clean 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 and check for leaks
Problem:
Leaks on system inlet/outlet connections
Correction:
Turn off water supply and turn on drinking water faucet to release pressure in
system. Remove tubing from fitting and make sure end of tubing is cut squarely
and free of burrs. Reinsert tubing into fitting, making sure to push tubing to a
hard stop. Hand-tighten compression nut first, then tighten 1 to 1 1/2 turns for
new compression nut. Tighten only 1/2 to 1 turn with wrench for previously
tightened compression nut.
NOTE: If leaks persist, or if there are other leaks in system, turn off water supply.
Problem:
Leaks on faucet / tubing connection
Correction:
Turn off water supply 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. Turn on saddle valve, and then turn off faucet to check
for leaks.
NOTE: If leaks persist, or if there are other leaks in system, turn off water supply.
Problem:
No water or decreased water flow.
Correction:
Check flow at faucet. The 4000 Nanotechnology Certified Under Counter
Filtration System
system should fill a gallon jug in approximately 2 minutes. Flow
rates will vary with individual household water pressure.
Correction:
Check filter cartridge installation. Make certain all filter cartridges are properly
oriented in filter housings.
Correction:
Replace filter cartridges.
