For Water Tanks with Pump Assemblies:
Tanks need to be emptied, pumps drained via the drain plug, and waterlines blown out. Ensure the waste and water tanks as well as the vent system (toilet tanks, bowls, urinals, and traps) are emptied before they are unplugged, with environmentally-friendly antifreeze added to the pump priming port(s) afterwards.
To Avoid Any Issues, Ensure Your:
- Plumbing/water lines are blown out or filled with antifreeze prior to shutdown.
- Fixtures and p-traps have antifreeze added.
- Urinal water lines (vertical drops to flush valve) need to be blown out and/or have antifreeze added.

Plumbing Winterization Checklist
Always Ensure That:
- During cooler months, you never disconnect heat (electricity) from the unit(s) until plumbing fixtures and lines have been drained and properly evacuated of all water.
- If this is not done, the pipes will freeze and burst. Charges will be applied if unit is not adequately drained.
