Close septic systems for winter the proper way
Winterize your seasonal cabin's septic system
For Minnesota cabin owners, knowing the proper way to close a septic system for the winter helps to ensure a more positive experience when opening your cabin the following spring!
Some tips from Extension's Septic System Owner's Guide:
- Completely drain plumbing and fill all traps with recreational vehicle (RV) antifreeze, even if the heat is left on. Do not use automotive antifreeze, salts or commercially available
- Turn off the water. If you have a high-efficiency furnace, reroute it to a floor drain or sump pump to prevent water from entering the septic system. If you leave the water on, eliminate leaks to prevent septic system freezing. Consider pumping the septic tank.
Stop cutting grass in the area around Labor Day to help insulate.
