Fall Plumbing Checklist for Michigan Winters (Freeze-Proof Your Home)

Michigan winters are hard on plumbing, and the best time to prepare is now — a mild fall afternoon, not a January emergency. This checklist covers the freeze-proofing and maintenance that prevents the calls we get most in deep winter: burst pipes, failed sumps, and no hot water. An hour of prep can save you a very expensive week.

Outdoor and exposed plumbing

• Disconnect and drain garden hoses. A hose left on a spigot traps water that freezes and can split the faucet and the pipe behind it.
• Shut off and drain outdoor faucets. If you have interior shutoffs for hose bibs, close them and drain the lines. Consider frost-proof replacements for chronically freezing spigots.
• Winterize irrigation systems. Blow out sprinkler lines before the first hard freeze.

Insulate the vulnerable spots

• Insulate exposed pipes in crawlspaces, garages, the basement rim joist, and along exterior walls with foam sleeves.
• Seal drafts where cold air reaches pipes — crawlspace vents, gaps around the foundation, and garage penetrations.
• Add heat tape to pipes that freeze every year, or have a plumber reroute chronically vulnerable runs.

This matters most in homes with long, exposed runs — a common situation in rural areas like Superior Township, where pipes to outbuildings and through unheated spaces are the first to freeze.

Check the water heater

Winter is peak demand for hot water, and it's the worst time for a heater to quit. Before the cold sets in, look for signs of trouble — rumbling, rust, or pooling water — and consider a flush to clear sediment. If your unit is over a decade old or showing symptoms, replace it now rather than during a January cold snap. Our water heater service can evaluate it before the rush.

Test the sump pump

Fall rains and the eventual spring thaw both test your sump system. Pour a bucket of water into the pit to confirm the pump kicks on and clears it, check that the discharge routes water away from the foundation, and make sure you have a battery backup for storm outages. A sump that fails during a wet stretch means a flooded basement.

Know your shutoffs

Before winter, make sure you (and everyone in the household) know where the main water shutoff is and that it actually works. If a pipe bursts, shutting the water off fast is your best defense. Test the valve now — old valves sometimes seize, and you don't want to discover that mid-emergency.

During extreme cold

When a hard freeze is forecast: open cabinet doors under sinks on exterior walls so warm air reaches the pipes, keep your thermostat steady (including when you travel), and let the most vulnerable faucet drip slightly to keep water moving. If a pipe does freeze, our frozen pipe service is available 24/7 to thaw it safely before it bursts.

The two shutoffs everyone should find before winter

Most of the winter emergencies we run could have been shorter — or avoided — if the homeowner knew two things ahead of time. First, where the main water shutoff is and that it actually turns; old valves seize, and you don't want to discover that with water spraying. Second, where and how to shut off and drain the outdoor spigots, because a hose left connected traps water that freezes and splits the faucet and the pipe behind it. Add insulation on the exposed runs, a tested sump pump before the thaw, and a quick water-heater look, and you've handled the bulk of what goes wrong in a Michigan winter — on a mild afternoon instead of during a freeze.
