Minor Leak Testing:
1. Ensure all appliances are off (no draw of propane).
2. Turn on the service valve.
3. Prime GasStop (push the gauge down 3-4 times) to equalize the system.
4. Turn the service valve off.
5. Your propane system should now be pressurized and isolated with no propane being used by appliances, nor coming in from the tank.
6. Watch GasStop gauge for 2 minutes.
