Mobile RV LP Gas System Inspection Across Florida

What a Complete LP System Inspection Covers

The inspection sequence begins at the tanks. Tank condition is evaluated - valve stems, hand wheel condition, and any visible corrosion on the tank body that would indicate structural compromise. The pigtail hoses connecting the tanks to the regulator are inspected for surface cracking, fitting condition, and connection security. The regulator is tested with a calibrated manometer to confirm it is delivering 11 inches of water column at the outlet - neither under-pressure nor over-pressure.

From the regulator outlet, the inspection follows the coach LP piping through the compartment and into the coach. Every threaded fitting, every compression fitting, and every coach penetration is inspected and marked for the soap test. The LP solenoid is tested by measuring voltage at the coil and observing that the valve opens cleanly when energized and closes completely when de-energized. The solenoid circuit back to the LP detector and the power supply is traced and verified.

At each appliance, the flex hose is inspected for surface condition, the appliance shutoff valve is operated through its full range to confirm it is not seized, and the burner orifice is inspected for debris or damage. The LP detector inside the coach is tested with a known propane source to verify it responds within its rated time. The full system pressure-decay test is the final step - 10 PSI applied to all coach piping with all appliance valves closed, held for three minutes, with a pass/fail documented in the written report.

Why Annual Inspection Is the Right Interval for Florida

The argument for annual LP inspection in Florida begins with temperature. Propane flex hoses carry an LP-service rating that assumes a maximum sustained temperature of approximately 120 degrees Fahrenheit. The interior of a Florida coach in direct summer sun regularly exceeds 140 degrees - above the material rating for some hose compounds. Over months of storage at these temperatures, the rubber compound loses plasticizers and begins the hardening process that leads to surface checking and eventually cracking. An annual inspection catches hoses in the surface-checking stage, when replacement is low-cost, before the crack-and-leak stage, when the risk is real.

Florida's salt air environment adds a second degradation mechanism for brass fittings. Copper alloys in salt air develop a green patina - a copper chloride compound - that is not merely cosmetic. The chloride compound is slightly porous and hygroscopic, meaning it absorbs moisture from the air, which continues the corrosion process beneath the visible surface. A brass fitting that looks slightly green but not obviously corroded can have significant thread degradation that will cause it to fail a pressure test. The annual inspection identifies these fittings before they become active leaks.

The third factor is Florida's wildlife. Mud dauber wasps, palmetto bugs, and assorted insects find RV propane appliance vents - particularly the water heater and furnace - attractive nesting sites during summer storage. An annual reactivation inspection that specifically checks vent paths and orifices for biological obstructions is the only way to clear these reliably. A coach reactivated after summer storage without an inspection has a meaningful probability of a blocked water heater or furnace vent, which produces incomplete combustion and appliance lockout on the first use.

The Written Report and What It Documents

The inspection concludes with a written report documenting every component inspected, the finding at each, and the overall system assessment. For components that pass with no issues, the report notes clean/serviceable. For components approaching the end of their service life but not yet failing, the report notes condition with a recommended action timeline. For components that failed the inspection, the report notes the specific finding and the required repair.

If the pressure-decay test passes, a certificate is issued with the inspection date, the technician's RVIA credentials, and the coach identification. This certificate is what campgrounds, RV parks, and insurance carriers request when they require documentation of LP system safety. Campgrounds that require LP certification typically accept the RVIA-certified technician certificate as meeting their requirement, though some specify a maximum age - typically one year - which is consistent with our recommended annual inspection interval.

The written report is also useful for your own purposes as an owner. It gives you a baseline for the system's condition at the time of inspection, a prioritized list of upcoming maintenance, and documentation for warranty claims if an appliance fails shortly after a certified inspection showed a specific component as within spec.

Storage Inspection Timing and Pre-Trip Inspection

The two highest-value times to inspect an RV LP system in Florida are: before the coach goes into summer storage, and when it comes out of summer storage. The pre-storage inspection catches any issues that would worsen over months of sitting - a weeping fitting will be an actively leaking fitting after six months. The post-storage inspection verifies that nothing degraded during storage and clears the coach for use before the first trip of the season.

A pre-trip LP safety check is a shorter version of the full inspection focused on the components most likely to create a problem in transit or at a remote site. It covers the regulator output, solenoid function, flex hose condition at each appliance, LP detector response, and a quick pressure-decay test. Most coaches pass the pre-trip check in under an hour. Those that do not have a known issue that is better addressed before departure than at a campground two states away.
