Hi,
My friend has a Culligan RO filter (under the sink). The faucet flow has pretty much stopped. We verified that water is being sent to the tank via the RO module (we disconnected the fitting and observed a pretty good stream of water). So it seems to be related to the tank.
How does the tank work? There is only one fitting so I'm guessing there is an internal tube from the fitting to the bottom of the tank. Does air pressure in the tank force the water out? Is there a bladder to seperate air/water?
Anything else we can check? When I tilt the tank water does come out of the top fitting. Also, I noticed that the tank fitting was somewhat loose and the teflon was not put on correctly. So it may have been water tight but not air tight.
Thanks

When water cease to come from the tank, it is almost always that the bladder is water-logged, or it has a hole in it.
If you have a three-gallon tank, weight it. If it weighs about 25lbs. then it is full of water and the bladder needs to be replaced or the whole tank in some cases. Also, if water comes out of the air valve, it could also sjhow the tank bladder is shot.
You need about 7-9 psi in the bladder with the tank empty.
All RO tanks, except Kinetico's, works on an air charge stored in the tank under (separate from) the water bladder. This type of system causes some problems like low volume and low pressure as the tank empties. It also causes the membrane to work harder and slower producing less water on a daily basis.
I would get it fixed so your drinking water can be the way you want it.

AS AN ADDITIONAL NOTE...
"We verified that water is being sent to the tank via the RO module (we disconnected the fitting and observed a pretty good stream of water)."
I WOULD CHECK THE WATER BEING PRODUCED....A RESIDENTIAL R/O WILL NOT PUT OUT A PRETTY GOOD STREAM OF WATER.....IT WILL ACTUALLY BE MORE LIKE DRIPS, UNLESS THE TDS IS REALLY HIGH, THEN ITS MORE LIKE OOZING!
