Testing for propane leaks on small cylinders

It is important to inspect your cylinder and outdoor gas appliances for leaks. Do this before using them for the first time each season, as well as on a regular basis. This can be accomplished with a simple “bubble” test:

  • Apply leak detector solution or thick soapy water to the connection(s) between the cylinder valve and the regulator outlet. These connections are marked with an “x” on the diagram to the right.
  • Slowly open the cylinder valve and watch for bubbles.
  • If bubbles appear, close the cylinder valve, tighten the connection, and repeat the process. If bubbles still appear, call your propane retailer immediately.
