Propane powers cooking, heat, and hot water off-grid. Understanding how to maintain your RV propane system safelyprotects you from leaks, underperformance, and mid-trip cold showers.
Know the Components
Typical LP systems include cylinders or a tank, pigtails, a two-stage regulator, hard lines/flexible hoses, shutoff valves, and appliances (stove/oven, furnace, water heater, fridge). Map yours so you know where to inspect and isolate.
Annual Leak and Pressure Checks
Perform an annual leak-down test and regulator check. Between pro services, use soapy water on exposed fittings anytime you change cylinders or smell gas. Bubbles = leaks. If in doubt, schedule a certified LP inspection at Daisy RV.
Cylinder and Regulator Health
Confirm cylinder requalification dates and that cylinders are stored upright. Inspect pigtails for cracks or green corrosion at the brass. Regulators should be level with the vent unobstructed; replace regulators showing icing in mild temps, whistling, or inconsistent pressure.
Appliance-Specific Care
- Furnace: Vacuum dust, inspect sail switch and flame.
- Water Heater: Clean burner tube and orifice; check anode (if Suburban).
- Fridge (LP mode): Clear flue, verify blue flame, and ensure proper ventilation.
- Cooktop/Oven: Clean burner ports; verify even flame without yellow tipping.
Detector and Ventilation
Test LP and CO detectors monthly; replace at end-of-life per manufacturer (commonly 5–7 years). Maintain exterior vents and screens clear of debris and insects.
Travel and Storage Practices
Turn off LP when refueling the tow vehicle and follow tunnel/ferry rules. For storage, close cylinder valves, cap lines, and keep compartments dry to prevent corrosion.
Troubleshooting Low Flow
If all appliances are weak, suspect an overfilled cylinder, frozen regulator, tripped excess flow device, or crushed hose. Open cylinder valves slowly to avoid triggering safety devices.
