Un-winterizing our Trailer

Tools and Materials

The only tool necessary to get our trailer prepared for camping is a small Phillips head screwdriver to open the access panel to gain access to the water heater bypass valve.

Necessary Steps

There are several steps necessary to un-winterize our trailer and prepare it for a long season of fun:

  • Turn on main battery switch
  • Fill the fresh water tank with some water
  • Add a cup of bleach to a gallon of water and pour it into the fresh water tank
  • Finish filling the fresh water tank
  • Turn the water pump valve to draw water from the fresh water tank
  • Turn on each sink and shower faucet until the antifreeze is evacuated from the pipes and you can smell bleach
  • Open water heater release valve
  • Run hot water until the water heater is full
  • Close the water heater release valve
  • Check the water heater plug for leaks
  • Leave the bleached water in the system for 24 hours
  • Drain the fresh water tank
  • Refill fresh water tank and run all faucets until the bleach smell is gone
