STEP FOUR
Locate the water pump, disconnect the inlet fitting ...
Here's the quick way to find the water pump:
Look on the outside of the trailer for the water fill ... the water tank will be just under that.
While you are there, check for a drain valve on the exterior side of the trailer or just underneath on the belly of the trailer. If it is there open it to begin draining the tank. Other manufacturers put the drain valve inside the unit, so if you don't find a drain valve on the outside, it will be inside near the tank.
Go inside the unit and locate the water storage tank according to your outside observation. The water pump will be very near the water tank.
Also, it helps to open a tap and turn on the pump ... the sound will help locate the pump.

... and install the winterizing hose ...
... insert the other end of the hose into the antifreeze jug ...
... an aftermarket kit is available for a permanent installation ... this is easily installed and comes with easy-to-follow directions.
