Winterize an RV water heater

The heater and bypass arrangement vary by model; trapped water can freeze.

What to check first

Locate the model instructions, bypass layout and drain procedure before freezing weather. Confirm the system is cool and power is off as instructed.

When to get help

If valves or tank type are unclear, schedule seasonal appliance service rather than guessing.

Your RV’s make, model and component instructions control. Stop use and seek qualified help for propane odor, smoke, active electrical danger, unsafe braking or other immediate hazards. This guide does not diagnose your RV or establish part compatibility.

Next step

Check the exact component manual and model number before following a model-specific procedure.
