RV Propane System Safety and Maintenance
Answers: How do I keep my RV propane system safe on a long-term site? · Updated
Propane is the one system where the do-it-yourself line is bright. Owners handle inspection, connections, and detector testing. Everything else belongs to a certified technician.
Quick answer
Test connections with soapy water twice a year, keep the regulator vent clear and pointing down, test your propane and carbon monoxide detectors monthly, keep cylinders within certification dates, and hire a qualified technician for any repair, regulator replacement, or suspected leak.
Owner-level checks
- Soapy-water leak test at hose and fitting joints.
- Regulator vent clear of mud, wasps, and debris.
- Hoses free of cracking and abrasion.
- Detectors tested monthly and replaced at their expiration date.
- DOT cylinders recertified on schedule; ASME tanks inspected per requirements.
If you smell gas
- 1Extinguish all flames and ignition sources.
- 2Shut off the gas at the tank if it is safe to reach.
- 3Get everyone out and ventilate.
- 4Do not operate switches inside the rig.
- 5Call the gas supplier or emergency services, then a qualified technician.
Appliance servicing
Furnaces, water heaters, and refrigerators running on propane need their burners and flues cleaned — a spider web in a burner tube is a classic no-heat call. Have this done professionally if you are not confident.
Frequently asked questions
How long do propane cylinders last before recertification?
Follow the requirements stamped on your cylinder and your propane supplier's guidance; suppliers will refuse an out-of-date cylinder.
Can I leave propane on all the time?
Many full-timers do for the water heater and furnace, but keep detectors working and shut the tank when the rig is unattended for long periods.
