Propane fuels a lot of what makes an RV comfortable—cooking, heating, hot water. But if there’s one thing you don’t want to mess around with, it’s a propane leak. A small issue can turn into a serious safety risk if left unchecked. That’s why a propane leak test should be part of regular RV maintenance.

Some leaks are obvious—you’ll smell propane. But others? They can sneak up on you, causing inefficiency, wasted fuel, or, worst case, a fire or explosion. A propane system should be checked at least once a year or anytime something doesn’t seem right.

What’s Included in a Propane Leak Test?

1. Checking for Leaks

A special gauge is used to test the whole propane system for a drop in pressure. If no leak is detected then the pressure is checked and adjusted if needed. This is when a faulty propane regulator will be found or skunk oil in the lines. Skunk oil is from a propane tank that was overfilled at some point. If this condition is left alone the regulator will need to be replaced and the skunk oil could make its way in the lines to expensive appliance gas valves. These valves can be expensive to change, so why take the chance.

2. Checking and Adjusting Propane Pressure

Most RV propane systems run at 11 inches of water column pressure with 50% of the total propane draw. Too much or too little, and appliances won’t work properly. I use a manometer to check the pressure and make sure it’s right where it should be. If it’s off, I adjust it so everything runs efficiently and safely.

3. Test Firing Appliances

Once I know the system is leak-free it’s time to fire up the appliances:

• Stove burners should ignite cleanly with a steady blue flame.
• Furnace should fire up without hesitation and provide consistent heat.
• Water heater should ignite and stay lit.
• Fridge should smoothly switch over to propane mode and run without issues.

If something isn’t working right, it could be due to a clogged burner, a failing regulator, or another issue that needs attention.

Other Important Propane System Maintenance

Inspect Hoses, Tanks, and Regulators

Even if there’s no leak, propane hoses can dry out and crack over time. Regulators usually last 10-15 years, but if they start failing, pressure levels can get unreliable. I always check for signs of rust, corrosion, skunk oil or wear to catch potential failures before they become a problem.

Know How to Shut Off the Propane Supply

If you ever suspect a leak, turn off the propane immediately at the tank. No lights, no electronics, no flames—just shut it down and get it checked out before using the system again.

When Should You Get a Propane Leak Test?

• Annually, as part of regular RV maintenance
• Before the first trip of the season, especially if the RV sat all winter
• If you smell propane or suspect a leak
• After replacing a propane regulator
• If appliances aren’t running properly
