Camco water heater maintenance differs from residential glass-lined tanks. RV environments add unique stressors — winterization, road vibration, freeze cycles, sediment from variable water sources, and the propane infrastructure that powers most RV water heaters. Camco's lineup is aftermarket RV/marine accessory specialist with a small line of replacement RV water heaters and water-heater accessories.
Pre-trip checks — every trip
- Verify bypass valves in correct position (winterize/use)
- Test propane shutoff valve operation
- Inspect anode rod (suburban-style units) — pull and inspect quarterly during heavy use
- Check T&P relief valve for residue or weep
- Verify access panel seal is intact (mice and water entry are common in RV bays)
Annual maintenance
1. Drain and flush the tank
RV water sources vary dramatically in mineral content. Sediment accumulates faster than in residential applications. Drain procedure:
- Turn off propane and electric power to the heater
- Open hot faucet inside RV to release pressure
- Remove anode rod or drain plug at base of tank
- Use a flush wand or compressed air to clear sediment
- Reinstall plug or anode rod with Teflon tape
2. Anode rod inspection (suburban-style tanks)
Camco RV tanks (where compatible with Suburban-style anodes) require annual anode inspection. Heavy use, hard-water sources, or extended off-grid water harvesting accelerate consumption. Replace when 75% consumed.
3. Burner and pilot inspection
For propane-fired models: inspect burner orifice for spider webs (extremely common in stored RVs), verify pilot flame is steady blue, check thermocouple/thermopile resistance.
4. Verify bypass valve operation
The bypass valve system allows the water heater to be isolated during winterizing or repairs. Verify both summer (in-use) and winter (bypass) positions move freely and seal correctly.
Winterizing — before every freeze
Required for any RV stored in temperatures that may drop below 32°F. Procedure:
- Drain the water heater completely
- Move bypass valves to "bypass" position
- Add RV antifreeze (non-toxic, pink) to the freshwater system
- Run antifreeze through hot lines until pink water comes out hot faucet
- Verify no water remains in heater bay (mice can nest in damp insulation)
De-winterizing in spring
- Drain antifreeze from freshwater system
- Flush fresh water through system until clear
- Reposition bypass valves to "in use"
- Fill water heater (verify no leaks at access panel)
- Run hot faucet until steady flow
- Turn on propane and verify ignition
Camco-specific notes
Camco replacement elements, anode rods, drain plugs, bypass valves, and tankless conversion kits for existing Atwood and Suburban OEM tanks. Camco Olympian 4-gallon and 6-gallon residential mini-tank. Used in RV after-market parts, replacement components, marine applications. Verify exact model and verify compatibility with maintenance procedures specific to that line — RV manufacturers sometimes customize OEM water heaters with brand-specific anode threads or bypass valve configurations.
Common RV maintenance mistakes
- Skipping anode inspection in RV environments (faster consumption than residential)
- Forgetting to bypass before winterizing (antifreeze contaminates tank)
- Powering on a drained tank (destroys elements immediately)
- Storing with bay access panel ajar (mice enter and damage wiring)
