Your entire propane system should be checked periodically by a trained propane service person.

What should be checked

1. Smell for propane odor.
2. Check cylinders and tanks for exterior rust, dents, and date.
3. Check that disconnected cylinders are plugged and disconnected piping is capped.
4. Check the liquid level gauge on the tank or cylinder if so equipped. Refill per Mid-West Propane guidelines.
5. Ensure the appliances are properly vented.
6. Check appliances for rusty or water-damaged gas control valves.
7. Check that the regulator:
   • vent is pointed downward to prevent blockage from ice
     
      
   • vent is not blocked by insects, mud daubers, wasp nest, spider cocoons, etc.
     
      
   • connector is protected from scratches or dents.
     
      
8. Check that cylinders:
   • are stored outdoors or in an open area in an upright position.
     
      
   • On portable appliances have shutoff valves firmly closed when the appliance is not being used.
     
      
   • Are away from a stove or fireplace, or not left in a hot car
     
      
   • are in a secure position
     
      
   • are used with a regulator
     
      
9. Check local laws, codes, or regulations to determine if propane-fueled appliances are permitted in below-grade locations.
10. After a gas-out, check that shutoff valves on the cylinder or tank are turned off.
11. When closing up the house for an extended period of time, check that the propane system has been shut off at the tank or cylinder and check that the appliances are shut off.
12. The propane system on any vehicle should be inspected periodically.
