RV Water Heater Accessories

What RV water heater accessories do you carry?

This collection covers 179 parts and accessories for Suburban and Atwood/Dometic water heaters: access doors and door skins, replacement covers, anode rods, drain plugs, thermostats, thermal cutoffs, gas valves, circuit boards, heating elements, T-handles, and bypass kits. If you need a complete unit instead of components, see our 10 gallon RV water heater collection.

How do I find the right replacement cover or access door for my RV water heater?

Match by water heater model number and tank capacity. Suburban uses an SW/SAW prefix (6, 10, 12, or 16 gallon), and Atwood/Dometic uses a G6A, GC6AA, or GC10A code stamped on the data plate behind the access door. Cover dimensions and color (polar white, colonial white, black) need to match the original, so confirm the part number before ordering.

How often should the anode rod in a Suburban water heater be replaced?

Inspect the anode rod at least once per camping season and replace it when more than 75% of the magnesium or aluminum core has eroded. Most full-time users replace it annually. Anode rods are only used in Suburban tanks (steel-lined); Atwood/Dometic tanks are aluminum-clad and do not use one. For seasonal storage prep, pair the new anode with items from our RV winterizing kits.

Will these accessories work with both gas and electric water heaters?

Most physical parts (covers, doors, anode rods, drain plugs, T-handles) fit both LP gas and gas/electric (DSI) models of the same tank size. Electrical components are model-specific: heating elements, circuit boards, and thermostats must match the exact configuration (SW6D vs SW6DE, for example). Check the suffix on your data plate, D for DSI gas only, DE for gas plus electric.

Do you ship water heater accessories with free shipping?

Yes, orders over $100 ship free within the contiguous US. Smaller items like anode rods, drain plugs, and thermostats ship via standard ground; access doors and covers ship in larger boxes but still qualify for the free shipping threshold.
