Florida Heat Effects on LP Regulators and Copper Fittings
The dual-stage LP regulator on a Class A coach contains a neoprene or EPDM diaphragm that flexes to maintain consistent outlet pressure as tank pressure varies between 200 PSI (full 30-lb tank at 90F) and 40 PSI (near-empty tank at 50F). In Florida summer heat, ambient temperatures inside the LP compartment reach 130-150F - above the 120F rated operating temperature for many OEM regulator diaphragms. At sustained temperatures above rating, neoprene loses approximately 30% of its elastic recovery per 1,000 hours of exposure. A regulator through five Florida summers may have a diaphragm that no longer seals consistently under load. Symptoms include appliances burning with yellow or orange flame instead of blue, water heater pilot outages on moderately windy days, and range burners that cycle pressure audibly during cooking. The Cavagna Group dual-stage regulator common on Tiffin and Monaco coaches has a diaphragm replacement kit for $28-35, but given labor cost, complete regulator replacement is more cost-effective after 5 years of Florida storage. Cavagna, Fairview, and Marshall Excelsior are the three main OEM regulator suppliers for Class A coaches. Any regulator replacement includes a full LP pressure test to confirm zero installation leaks.
Safe LP Line Pressure Release for Storage
Releasing residual LP line pressure before extended storage prevents regulator seat damage from pressure spikes when the system is first energized months later, and reduces wear on solenoid valve seats under constant pressure when the system is live. The correct procedure for a Tiffin dual-zone LP system: close both tank service valves firmly by hand - not with a wrench, as service valve seats are soft brass and overtightening damages them. Open the range surface burner valve for 10-15 seconds until the flame dies from line depletion. Hold the oven pilot button for 20 seconds with no ignition to purge any remaining oven line pressure. Verify all burner and appliance valves are closed. Switch the LP system enable breaker to off in the power distribution center to de-energize the LP solenoid valves. The Asco Series 8 solenoids common in Tiffin coaches have a rated continuous duty cycle, but seal wear still accumulates under sustained pressure. A common storage mistake is closing the exterior tank valve and assuming the LP system is fully depressurized - the downstream side of the regulator still holds pressure at regulated supply pressure (11 inches water column for low-pressure systems) and must be purged through an appliance valve.

Case Study: LP System Shutdown Repair
RV: 2019 Tiffin Allegro Red 37BA • Location: Manatee Hammock Campground, Site 29 • City:
Symptom: Owner detected a faint propane odor near the exterior LP compartment after six months of Florida storage. The smell was present only within 3 feet of the compartment door on calm mornings. Interior propane detector did not alarm. Tanks showed pressure on the exterior gauge.
Diagnosis: Jesse Earl used a Fieldpiece SRL8 combustible gas leak detector and found 200 PPM at the inlet side of the Cavagna dual-stage regulator, above the 50 PPM investigation threshold. The leak traced to the soft copper inlet line compression fitting - the ferrule had work-hardened and developed a hairline gap from heat cycling. Florida day-night temperature swings of 20-25F can cycle a copper fitting through its yield point over 180 storage days. Leak rate measured at 0.004 cubic inches per minute - slow enough to avoid triggering the interior detector but sufficient to produce outdoor odor in calm conditions. Regulator output variance tested at 0.5 oz per square inch over five minutes - outside the acceptable plus or minus 0.3 oz range - indicating beginning diaphragm degradation in the 5-year-old unit.
