A step-by-step checklist for closing up your Hubbard County cabin before the freeze.
Closing up the lake cabin is a fall ritual across Park Rapids, Nevis, Akeley, and the rest of Hubbard County. Do it right and you come back in spring to a cabin that is ready to enjoy. Skip a step and you can return to burst pipes, water damage, and a costly repair before the season even starts. The single biggest risk to an unheated Minnesota cabin over winter is water freezing inside the plumbing. Water expands as it freezes, and that pressure cracks pipes, fittings, valves, and fixtures. This checklist walks through how to get the water out of the system so there is nothing left to freeze.
A quick note before you start: every cabin is plumbed a little differently. Some are on a drilled well with a pressure tank, some draw from the lake, some have a basement and some sit on a slab or crawl space. If you are unsure about your setup, or you would rather have it done right the first time, our team winterizes cabins around the Park Rapids area every fall.
Start by cutting off the water source. If your cabin is on a well, turn off the power to the well pump at the breaker and close the main shutoff valve. If you are on a different supply, close the main valve where water enters the cabin. This stops any new water from entering the system while you drain it. With the supply off, you can work through the rest of the cabin knowing the lines will not refill behind you.
Open every faucet in the cabin, hot and cold, including kitchen, bathroom, and any utility sinks. Open outdoor spigots and disconnect garden hoses. Flush the toilets to empty the tanks and bowls as much as possible. Then open the lowest drain point in the system, often a drain valve near where the water comes in or at the bottom of the pressure tank, to let the lines empty by gravity. Leaving the faucets open lets air in so the water drains fully instead of getting trapped. For a thorough job, blowing out the lines with compressed air clears the water that gravity leaves behind in low spots and horizontal runs, which is exactly where freezes tend to happen.
A tank of water sitting in an unheated cabin all winter will freeze and can crack the tank. Turn off the power or gas to the water heater first. Connect a hose to the drain valve at the bottom, run it to a floor drain or outside, and open the valve to empty the tank. Opening a hot-water faucet upstairs helps it drain faster. Make sure the heater is fully empty before you leave. If you have a tankless water heater, it has its own draining procedure, so follow the manufacturer's instructions or have it serviced.
If your cabin has a water softener, iron filter, or other treatment equipment, it holds water too and needs to be drained or bypassed according to its instructions. The same goes for any whole-house filter housings. Do not overlook this gear, because a cracked softener tank or filter housing is just as much of a spring surprise as a burst pipe.
Even after the supply lines are drained, every sink, tub, shower, floor drain, and toilet has a P-trap that holds standing water to block sewer gas. That trapped water can freeze and crack the trap. Pour non-toxic RV or plumbing antifreeze, the pink kind made for potable systems, into each drain so it fills the trap. Pour some into the toilet bowl and tank as well after draining them. Use plumbing antifreeze, not automotive antifreeze, which is toxic and not meant for these systems.
Toilets need extra attention because they hold water in the tank, the bowl, and the trap. Shut off the supply to each toilet, flush to empty the tank, and sponge out or use a wet vacuum on any water left in the tank and bowl. Then add plumbing antifreeze to the bowl so the trap is protected. A cracked toilet from a hard freeze is a common and avoidable spring discovery.
Do one last pass through the cabin. Confirm every faucet is open, the water heater is empty, the supply is off, treatment equipment is drained, and antifreeze is in every trap and toilet. Check for any appliance that uses water, such as a dishwasher, clothes washer, or ice maker, and drain those lines too. If the cabin will keep any heat over winter, set the thermostat to a safe minimum, but if it will be fully unheated, the goal is simply to have no water left anywhere in the plumbing.
A burst pipe in a closed-up cabin can run undetected for weeks. Water keeps flowing if the supply was left on, soaking floors, walls, and belongings, and the bill for repairs and water damage far exceeds the cost of a careful winterization. In our climate, with a heating season that stretches from early fall into spring, the freeze window is long and the margin for error is small. Taking the time to drain everything, or having a professional do it, is cheap insurance for an expensive asset.
When you come back in spring, the process reverses: remove or flush out the antifreeze, close the drain valves, restore the water supply, refill the water heater before turning it back on, and check every fixture and connection for leaks as the system comes back up to pressure. This is also a good time to address anything you noticed in the fall, such as a slow drain, a dripping valve, or aging water treatment equipment.
