Freezing damage prevention and seasonal plumbing protection on the 2023 Airstream Interstate 19 are managed by low-point drain plugs, non-toxic propylene glycol RV antifreeze, and holding tank heating pads.
How to Fix It:
-
Drain All Holding Tanks: Completely empty both gray and black water holding tanks along with the freshwater tank at an approved dump station.
-
Open Low-Point Drains: Remove plugs or open valves on the water lines to let all residual water escape completely from the plumbing network.
-
Pump RV Antifreeze: Run non-toxic RV antifreeze through all sink drains and the shower P-trap to protect wastewater lines from freezing and cracking.
