Winterizing your lake cabin plumbing requires several critical steps to prevent costly freeze damage. Start by shutting off the main water supply and draining all pipes completely, including faucets, toilets, and your water heater. Pour non-toxic antifreeze into all drains, toilet bowls, and tanks after they’ve been emptied. If you have well systems or specialized equipment, ensure these are properly winterized according to manufacturer guidelines.
Why Proper Winterization Is Essential
Minnesota and Wisconsin lake cabin owners know that winter temperatures can plummet well below freezing for extended periods. When water freezes inside pipes, it expands with tremendous force—enough to split copper, PVC, or steel pipes. The damage often remains hidden until spring when you reopen the cabin and suddenly discover burst pipes, damaged fixtures, and potential water damage throughout your property.
Proper winterization isn’t just about preventing inconvenience—it’s about protecting your investment. A single burst pipe can cause thousands in damage, far exceeding the cost of proper winterization. Plus, many insurance policies may not fully cover freeze damage if proper precautions weren’t taken.
Complete Winterization Checklist
1. Shut Off The Main Water Supply
Begin by locating your cabin’s main water shut-off valve. This is typically located where the water line enters your home, often in a basement, crawl space, or utility room. Turn this valve completely off.
If your cabin uses well water, turn off the power to the well pump at your electrical panel. For municipal water supplies, consider contacting the water department to shut off service at the street if you’ll be away for the entire season.
2. Drain All Water From The System
After shutting off the water supply, open all faucets in the cabin (both hot and cold) to begin draining the system. Don’t forget outside spigots and shower heads.
Flush all toilets repeatedly until water no longer fills the tank. Remove any remaining water in the toilet tanks and bowls using a small cup and sponge or wet vacuum.
3. Water Heater Drainage
Turn off your water heater’s power source (electricity or gas). For electric heaters, shut off the appropriate breaker. For gas heaters, turn the gas valve to the “pilot” or “off” position.
Connect a garden hose to the drain valve at the bottom of the water heater and direct it to a floor drain or outside. Open the valve and let all water drain completely. Leave the drain valve open throughout winter.
4. Add Antifreeze Protection
Purchase RV/marine-grade, non-toxic propylene glycol antifreeze specifically designed for plumbing systems. Never use automotive antifreeze, which is highly toxic.
Pour about 1-2 cups of antifreeze down each drain in the cabin (sinks, showers, tubs, floor drains). Pour approximately 1-2 cups into each toilet bowl and tank after removing as much water as possible.
5. Appliance Winterization
For dishwashers, run a brief cycle to remove water from the pump, then add a cup of antifreeze.
For washing machines, set the machine to a brief wash cycle, shut it off once it fills with water, and then drain this water. Add antifreeze to the tub afterward.
Refrigerators with ice makers or water dispensers need special attention—disconnect water lines and blow them out or add antifreeze according to manufacturer guidelines.
6. Special Considerations for Well Systems
If your cabin uses a well, the pump system requires additional attention. After shutting off power to the pump:
- Drain the pressure tank completely
- Remove and store any water filters
- Drain all lines leading to and from the pressure tank
- Consider adding antifreeze to the jet pump if it’s above the frost line
7. Inspect for Potential Problem Areas
Before leaving, check for any areas where pipes might be exposed to extreme cold, such as:
- Pipes along exterior walls
- Plumbing in unheated areas
- Pipes in crawl spaces or unfinished basements
Consider adding extra insulation in these areas as an additional precaution.
