Florida Storage Hazards That Affect Spring Startup
Florida heat, humidity, and insect populations create de-winterization complications not found in northern climates. The primary biological hazard is the mud dauber wasp (Sceliphron caementarium), active year-round in central and south Florida and capable of building clay nests inside any sheltered tube or cavity within days of an RV sitting unattended. Water heater combustion chambers, furnace flue tubes, refrigerator burner orifices, and range burner ports are all common nesting sites. A blocked pilot orifice on an Atwood GCH10A or Suburban SW6DE produces a click-no-light symptom that owners mistake for igniter failure. Jesse Earl carries drill bit wire brushes in sizes #54 through #60 (0.035 to 0.055 inch) to clear blocked orifices without enlarging them. The second Florida-specific hazard is UV degradation of faucet cartridges during summer storage in direct sun. Moen 1222 and similar cartridges common in Heartland coaches can shrink slightly after six months of storage, causing drips that appear only when water pressure is restored. The third hazard is PEX fitting relaxation - propylene glycol has slight plasticizing properties that cause compression ferrules to cold-flow over four or more storage months, requiring re-torquing at spring startup. Push-fit SharkBite connections are immune to cold-flow but should be inspected for debris at the collet.
Water Heater Re-Commissioning - Fill Before Energizing
The most critical step in de-winterization is re-commissioning the water heater before operating any other appliance. An Atwood GCH10A 10-gallon or Suburban SW6DE 6-gallon heater energized while even partially empty burns out the electric heating element within minutes - the element is rated for immersed operation only. Jesse Earl's procedure: return bypass valves to normal flow position, open a hot-water faucet at the farthest fixture from the heater, connect city water or start the water pump, and wait until a steady stream flows before closing it - this confirms the tank is full. Only then is the heater energized on electric mode. Tank fill time on a cold 10-gallon Atwood via 40 PSI city water takes approximately 90 seconds. Rushing this step is the most common cause of electric element replacement calls Coast to Coast RV Repair receives in March and April. The replacement element for an Atwood GCH10A costs $28-45 in parts plus labor - easily avoided by the 90-second fill verification. Dometic DWHE-60SM tankless heaters do not have this risk but need combustion chamber inspection for mud dauber nests at the burner assembly.

Case Study: De-Winterization and Spring Startup Repair
RV: 2019 Heartland Bighorn 3760EL • Location: Blue Spring State Park, Site 7 • City:
Symptom: Owner connected city water and opened the kitchen faucet after four months of storage - water ran pink for 30 seconds then cleared, but a wet spot appeared at the base of the kitchen slide 10 minutes later. The Atwood water heater pilot would not light after three attempts.
Diagnosis: The wet spot at the slide base traced to a 3/8-inch supply line compression fitting at the kitchen faucet tailpiece - the ferrule had loosened during storage temperature cycling. Torque test confirmed the nut turned 1/4 turn before resistance, indicating cold-flow relaxation. Water heater pilot failure traced to a mud dauber wasp nest blocking the pilot orifice. Jesse Earl found clay nest material across the pilot tube orifice and inside the combustion chamber vent. The oven burner also failed ignition for the same reason.
