  3. Inspect each part for leaks or damaged pipes. Note any issues that need a pro.
  4. Connect the RV to a potable water supply and close all drains and faucets.
  5. Fill up the fresh water tank with clean drinking-quality water. Turn on the water pump and run the faucets for a few minutes to avoid air pockets.

Turn on the propane tanks (if applicable) for hot water. Check all appliances, connections, and valves to prevent future issues.

Now your RV hot water heater is ready for use – enjoy a worry-free camping season with functional hot water! Pro tip: Regular maintenance and inspections will increase the life of the plumbing system.

Drain the hot water heater

If you wanna keep your hot water heater in tip-top shape, here’s what to do:

  1. Locate the drain valve on the bottom of the tank and open it. Have something to catch the water flow.
  2. Open all the hot water faucets in your RV to release any pressure built up in the lines.
  3. Finally, close the drain valve and faucets once all the water has been drained.

Regularly check and maintain your hot water heater too. Inspect for leaks, make sure it’s insulated properly, and clean or replace filters as needed. Or else, you’ll get a nasty surprise. Like I did – when I neglected to properly drain my hot water heater before winterizing my RV, residual water froze and caused serious damage.
