When the weather takes a turn and nights dip down to freezing temperatures, you know it's time to winterize.


Freezing climates can damage the camper’s plumbing system and equipment. The camper must be drained, blown out, and have antifreeze protection before storing in below-freezing temperatures in fall/ winter. This is done through a process called winterizing. Be sure to always use a non-ethanol-based antifreeze when winterizing your camper.


If you are having trouble getting the Nautilus panel to siphon the antifreeze into the system, here are a few tips you can try:


  • Make sure all faucets, fixtures, and drain valves are closed. Otherwise, the pump won’t be able to pressurize the lines. A common culprit is that the yellow Alde safety drain is left open or a faucet is open. 
  • Shake the hose up and down in the jug/bucket.
  • Use a short hose or cut-off hose. The pump will have a harder time with a longer hose.
  • Raise the hose above the level of the pump and pour into freeze directly into the hose using a funnel to help get it started.
  • The pump may be dry and need to be primed. You can force antifreeze into the inlet side of the pump or unscrew the clear cap on the sediment filter on the inlet of the pump and pour some antifreeze in.


You can also use aftermarket winterizing adapters to help make the process easier:
Winterizing Adapter Kit - Allows you to hookup directly to the water pump inlet to make siphoning easier.
Antifreeze Hand Pump - Allows you to pump antifreeze directly into water inlet. (This can be handy if the pump is dry and needs primed)
