Finding a Nitrogen Leak
Checking Supply Hose and Tubing
Visually check all tubes for cracks or holes.
Checking the Regulator (must be original WineKeeperTM regulator for safety and performance):
1. Disconnect the quick-connect fitting on the supply tube where it joins the regulator.
2. Turn on the cylinder. (Make a note of the pressure registered on the regulator gauge).
3. Turn off the cylinder.
4. Wait 20-30 minutes, if the pressure registered on the regulator has dropped, the problem is in the
regulator.
5. Use soapy water to find the leak or return the regulator to WineKeeper for repair.
6. If leak is not in the regulator, or the regulator leak has been repaired, continue.
Checking the system (For this test, the WineKeeper should be connected to wine bottles with 2-3 ounces
of liquid for best results.)
1. Reconnect the supply line and open the cylinder valve.
2. Leave the valve open for 30 seconds to completely pressurize the system.
3. Close off the nitrogen pinch clamps. Stopper assemblies must be in the wine bottles and
tightened down at this time.
4. Turn off the cylinder valve and note the pressure on the regulator’s gauge.
5. Leave the unit undisturbed for 20 minutes.
6. If the pressure drops, your problem is in the supply line between the regulator and the pinch
clamps. If the pressure does not drop, continue to step #7. Check the supply tubes where they
pass through the cabinet for holes, cracks, or chafing.
7. While observing the cylinder contents on the regulator’s pressure gauge, open and close each
pinch clamp one at a time. Stop if you see the pressure gauge drop while the pinch clamp is open,
because you have found a problem. It could be that the stopper-assembly has not been tightened
into the bottle correctly, that the tube below the pinch clamp has a hole, or that the latex ring has
become excessively worn. Address each of these possibilities and repeat these steps if necessary. If
no leak is found, human error is suspected as the cause of the leak.
8. If this problem continues contact WineKeeper for additional help.
Note: If the stopper assembly appears to be leaking wine, tighten the stainless steel hose clamp that
connects the clear wine tube to the stainless steel tube right above the stopper assembly. Look for a leak
anywhere in the wine tube or the barb on the back of the thru-wall inside the cabinet. Remember that
your WineKeeper should be cleaned at least once a month.
