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.
