Debarghya Roy

Empty your RV hot water heater for proper functioning and longevity. Without regular maintenance, sediment can clog it, reduce heating efficiency and even damage it. Here are instructions on how to drain and clean it effectively.

Key Takeaways


  1. Locate the drain plug or valve at the bottom of the tank. It’s usually made of plastic and can be removed with a socket wrench or hand tool. Before removing, switch off the power and let it cool.
  2. Place a container below the plug to catch any water that comes out. It needs to be large enough as several gallons may accumulate. Open the pressure relief valve at the top of the unit too.
  3. Drain most of the water from the hot water heater. Remove any sediment buildup by flushing it with fresh water. Attach a garden hose to a nearby faucet and insert it into the opening. Let the fresh water flow for a few minutes.
  4. Clean the hot water tank with hydrogen peroxide to eliminate bacteria or foul odors. Mix one part hydrogen peroxide with five parts fresh water and pour it in. Let it sit for an hour before draining completely.
  5. Draining the tank depends on usage and personal preference. Some do it every few weeks, others once a year. Decide what’s best for your water system.

Precautions and Safety Measures to emptying an RV hot water heater

Safety must come first when emptying an RV hot water heater. Here are a few key things to keep in mind:

  • Switch off the power source and let it cool down.
  • Turn off the propane or gas.
  • Release pressure by pulling the pressure relief valve.
  • Put a container under the drain plug or valve.
  • Be ready for some splashing as you remove the plug.
  • Use caution when loosening or removing the drain plug.
  • Take your time draining the tank completely.

Maintenance is essential for your heater’s longevity. Clean it with hydrogen peroxide every once in a while. To prevent sediment buildup, drain the tank at least yearly. This helps avoid clogs & extends its life.

With the right tools and a sense of humor, you can drain your RV hot water heater like a pro!
