WATER LINE DRAINS
The freshwater system is typically equipped with at least one water drain which extend downward
below the chassis frame. Removal of the threaded drain cap will allow water to drain out of the fresh
water system. It will still be necessary to add RV antifreeze in order to fully winterize the water system.
WINTERIZATION OF PLUMBING SYSTEM
It will be necessary to winterize the water system of your RV when storing or using the trailer in
subfreezing weather. Failure to properly drain and winterize the water system will result in freeze
damage this is not covered under any warranty.
1. Park the recreational vehicle on a level surface.
2. Completely drain the black and grey waste water tanks.
3. Turn the water pump off, and then open all faucets, low-point drains, water heater exterior drain
plug, and fresh water tank drain.
4. When completely drained, close the faucets, and drains.
5. Remove water filter (if so equipped)
6. Position the water heater bypass valves to closed top and bottom with the center valve open. Note, if
properly drained of water, it is not necessary to fill the water heater with RV antifreeze. Antifreeze (and
water) is prevented from entering the water heater when valves are in the winterization mode.
7. Remove the inlet line to the water pump and connect a temporary hose from the inlet side of pump
to a container of RV antifreeze.
8. Run the water pump until the RV antifreeze flows freely and is visible on both the cold and hot
portions of each faucet.
9. Flush the toilet multiple times until the antifreeze is visible.
10. Add several cups of RV antifreeze to the kitchen sink drains, the bath sink drain and the tub/shower
drain.
11. Reinstall the drain plug on exterior of water heater.
12. Remove the temporary hose at water pump and reconnect original water line.
13. Only use non-toxic RV anti-freeze.
DO NOT
use automotive antifreeze to winterize your RV as serious injury or death may occur from
ingestion of toxic antifreeze. Be sure to discuss winterization techniques and needs with your dealer
who is familiar with your local climate. 40 De - Winterization of the freshwater system, the following
procedures are recommended when removing the RV anti-freeze from the water system in preparation
of vehicle use.

3. Run the hot and cold side of each faucet until the water is no longer tinted by the RV antifreeze.
4. Flush toilet until water is clear.
5. Drain the fresh water tank.
6. Perform the water system sanitization as prescribed in this manual.
7. Install a new water filter (if so equipped).
8. Upon completion of the sanitization process, change the water heater bypass valves to the normal
