How to Winterize a RV

Introduction

With some help from a friend, you can winterize your RV. No one wants to have to replace a broken line or tank in the spring, so taking some simple precautions after the last camping trip makes sense. Follow these steps, and you can winterize your RV in no time.

Instructions

Difficulty: Moderately Easy

Steps

1

Step One

Drain your fresh water tank and hot water heater. You can speed up the process by opening the water taps in the RV.
2

Step Two

Dump the black and gray water holding tanks. Flush them well. Leave the gray water valve open.
3

Step Three

Bypass the hot water heater with a water heater bypass kit. Or, you can join the two water lines that come into the hot water heater with a temporary bypass kit. You don't have to put antifreeze in the hot water tank.
4

Step Four

Blow out the water line in your RV with a compressed air adaptor. Ask someone to help you with this. One by one, open each tap and let the air and water through. Don't forget the shower and toilet as well.
5

Step Five

Insert the end of antifreeze winterize tubing into the gallon jug of RV antifreeze. Or, you can use the intake hose. Start the fresh water pump. Beginning with the farthest tap from the pump, open each tap until it runs red. Shut the faucet once the water changes color. Again, don't forget the shower and toilet. Close the gray water valve. Pour some antifreeze down each drain and toilet.
6

Step Six

Remove all batteries. Put them somewhere where they can't freeze during the winter months.
7

Step Seven

Take all foodstuffs from the RV. Spray for insects. Make sure you block all the small holes. Put out rodent killer.

Tips & Warnings

  • Never use automotive antifreeze.
  • When releasing air or water, don't exceed more than 40 pounds per square inch, or psi, of pressure.
