Seasonal homes or cabins require special attention before winter sets in to ensure the septic system stays protected during periods of disuse. Here are some steps to winterize a seasonal septic system:
- Pump the tank: Have your septic tank pumped before leaving to remove liquid that could freeze.
- Turn off water: Shut off the main water supply, and drain all fixtures and pipes.
- Add antifreeze: Use RV antifreeze in toilet bowls and traps to prevent freezing.
- Insulate: Consider adding extra insulation to pipes and the tank if they’re accessible.
- Mark system components: Place markers to indicate the location of your tank and drain field to prevent accidental damage from snow removal equipment.
