Summer Is Here. Time To De-Winterize Your RV!

Summer Is Here. Time To De-Winterize Your RV!

If the unit was winterized you need to get it ready for use by de-winterizing it. With the bypass for the water heater still in the bypass mode, connect up a hose to your city water connection.

  1. Turn the water on and run the taps in the coach until you have no more colouring of the antifreeze.
  2. Run all the taps, both hot and cold, flush the toilet, and if you have an exterior shower, run water through both hot and cold.
  3. Once the water runs clear for all taps then turn the bypass into the normal mode. This will allow you to fill the hot water tank.
  4. In order for the hot water tank to fill right up you will need to open a hot water tap until all the air finishes coming out and you have a steady stream of water.
  5. Fill the fresh water tank. As this is filling up, you can check inside cupboards, and exterior compartments where water lines run for any signs of leakage from the system.
  6. Now that the hot water tank is full of water, you can run it through the cycle on 120VAC and also with propane as a fuel.

If you have a towed vehicle, you need to hook it up and make sure that the hitch, etc. is all working properly.

Once you are hooked:

  1. Connect your trailer lights and verify that all lights work.
  2. On a motorized unit check all under hood fluid levels, before you start the engine.

NOTE: automatic transmission fluid level must be checked with the vehicle running and up to normal operating temperature. Also check the oil in the generator if the unit is equipped with one.

If the RV is equipped with slideout(s):

  1. Make sure that they all open and close fully and are sealed in both the open and closed positions. Check the leveling system/jacks that they retract fully and move back to a support position.
  2. If the unit has hydraulic slideouts or leveling systems, you need to make sure that the hydraulic fluid level is topped up. This can only be checked with all jacks and slideouts retracted.
  3. If your unit is equipped with awnings, you want to make sure they all open and close and the condition of the fabric is good. This includes all window awnings, slideout toppers, etc.

If equipped with a generator:

  1. Start it up and after it runs for a few minutes you can start turning on 120VAC equipment. You need to run it under at least a 50% load for 20 minutes or longer.
  2. Run the fridge on 120VAC and any other resistive (heater) type loads, an air conditioner is not a good load once an air conditioner comes up to speed its amperage requirement drops.

Check the air pressure in all tires:

  1. Tires need to be checked when they are cold and the pressure should be as recommended by the coach manufacturer.
  2. Check the tires for any tread deformities, uneven wear patterns, etc.

The best way for you to help make sure that you have a great RV season is to make sure you have tried all the systems. It is best to have a checklist that you can use for equipping the unit for your season of RVing. This will help to ensure you have everything that you require for your happy camping season.
