Whether you’re a seasoned road warrior or new to the RV lifestyle, understanding how to check for propane leaks in your motorhome or travel trailer is essential for your safety and peace of mind. Propane is a commonly used fuel for cooking, heating, and powering appliances in RVs, but it’s crucial to ensure that your propane system is leak-free to avoid potential hazards. In this guide, we’ll walk you through the process of checking for propane leaks, the tools or devices you’ll need, safety precautions to keep in mind, and when to consider seeking professional help.

Tools and Devices Needed Before You Begin:

Propane Leak Detector: Invest in a quality propane leak detector. This inexpensive handheld device can detect even the smallest propane leaks. It’s an essential tool that every RV owner should have. They cost as little as $20 and can be found at most hardware stores or on Amazon.

Soapy Water Solution: Prepare a soapy water solution by mixing liquid dish soap with water in a spray bottle. This solution will help you identify propane leaks by creating bubbles at the leak points. You also have the option to purchase a leak detection solution. You can find this Camco solution at most Camping World stores or on Amazon.

Manometer: A manometer is a tool used to measure the pressure of propane in a closed system such as a propane line. Generally these are used by certified propane mechanics and are not recommended for basic RV owners. They are used find leaks in a propane system that is not easily found with previous methods mentioned here. A manometer will verify that the pressure in the propane system is stable and within the recommended range. Any significant deviations from the expected pressure levels could indicate a leak or a problem with the propane system that requires further investigation or repair.

Safety Procautions

Safety should always be your top priority when working with propane. Follow these safety precautions:

1. Ventilate the Area: Before checking for propane leaks, ensure that the area is well-ventilated to prevent the buildup of propane gas.
2. Turn Off Appliances: Turn off all propane-powered appliances, including stoves, ovens, water heaters, and furnaces, before conducting the leak check.
3. No Smoking or Open Flames: Propane is highly flammable, so smoking or using open flames near the propane system is extremely dangerous. So, put out that cigarette before you start working.
4. Wear Protective Gear: Consider wearing gloves to protect your hands while working with propane. Propane contains an oil to give it that familiar odor. This oil can get on your fingers and your hands will smell like propane even after washing up.

Checking for Leaks

Follow these steps to check for propane leaks around your motorhome or travel trailer:

1. Perform a Visual Inspection: Start by visually inspecting your propane system for any signs of damage, such as cracked hoses or corroded fittings. Start at the propane tank itself and inspect the regulator, the fill connections, the vent connection, and hoses.
2. Turn the Gas Supply On: Open the valve on the propane tank to allow gas to flow through the system.
3. Use the Propane Leak Detector: Turn on the propane leak detector and slowly move it along the propane system, focusing on the connections and fittings. If the detector beeps or lights up, it indicates the presence of a propane leak. The image below shows that there is a leak somewhere near the fill connection.

1. Check for Bubbles: The leak detector will give you an idea of where the leak is coming from, but checking for bubbles will help you pin-point the link. Spray the soapy water solution onto the connections and fittings. If there’s a propane leak, you’ll see small bubbles forming at the leak points. For example, using a soap solution we determined that our leak was not at the fill connection, but instead it was leaking at the small vent connection to the right of the yellow fill connection.
2. Tighten Loose Connections: Often a leak can be caused by a loos connection which can be an easy fix. If you identify any loose connections or fittings, use an adjustable wrench to tighten them. Be careful not to overtighten, as this can cause damage. In the example above, it was an easy fix. We were able to tighten the vent connection with a wrench.
3. Recheck for Leaks: After tightening any loose connections, repeat the leak check using the propane leak detector and soapy water solution to ensure that the leaks have been resolved.

If you are unable to resolve a leak yourself, trun off the propane at the tank and turn off all appliances that run on propane until you are able to resolve the issue.

When to Call for Help

While checking for propane leaks is a task that many RV owners can handle themselves, there are instances where it’s best to call a professional:

1. Persistent Leaks: If you’re unable to locate or fix a propane leak on your own, it’s time to call a professional propane technician. Persistent leaks could indicate a more serious issue that requires professional expertise.
2. Complex Repairs: Some propane system repairs, such as replacing a faulty regulator or repairing a damaged propane line, may require specialized knowledge and tools. In such cases, it’s best to leave the repairs to a qualified professional.
3. Safety Concerns: If you’re unsure about the safety of your propane system or if you suspect a major leak, evacuate the area immediately and call emergency services. Never attempt to repair a propane leak if you feel unsafe.
