Spring Plumbing Checklist for Northern Michigan Homeowners

Northern Michigan winters are brutal on plumbing. Months of sub-zero temperatures, freeze-thaw cycles, and snow load stress pipes, sump pumps, outdoor fixtures, and water heaters in ways that don't always show up until spring. By the time the ice leaves Torch Lake, your plumbing has been through the wringer.

The good news is that a quick walk-through in early spring can catch most of the damage before it becomes a real problem. Here's what to check — and what to call a plumber about before summer hits.

1. Inspect for Frozen Pipe Damage

Pipes that freeze don't always burst immediately — sometimes they develop small cracks that only start leaking once the ice thaws and water pressure returns. Walk through your basement, crawl space, and utility rooms in early April and look for:

• Water stains or rust streaks on walls, ceilings, and joists
• Damp insulation around pipes
• Unusual drops in water pressure throughout the house
• Any spot where a pipe looks bowed, cracked, or has a visible repair wrap from a previous freeze

Pay extra attention to pipes running along exterior walls, through unheated garages, or in crawl spaces — those are the first places to freeze and the last places people look. If you find moisture anywhere near a pipe, don't assume it's condensation. Have it looked at.

Cabin and seasonal home owners: this is especially important if your property sat unoccupied over winter. Even with the water shut off, a slow leak from a cracked fitting can do significant damage over months. Walk the whole system before you turn the water back on.

2. Test Your Sump Pump Before the Rains Come

Spring snowmelt in Northern Michigan can dump a lot of water into the ground fast — and if your sump pump has been sitting idle all winter, it may not be ready for it. Sump pump failures are one of the most common causes of basement flooding in April and May.

Testing yours takes about two minutes: slowly pour a bucket of water into the sump pit and watch for the float to trigger the pump. It should activate, drain the pit, and shut off cleanly. If it hesitates, runs continuously, makes grinding noises, or doesn't kick on at all, you have a problem.

While you're at it, check the discharge line to make sure it's clear of ice or debris from winter. A blocked discharge line can burn out the pump motor or flood the pit even when the pump is technically running. And if you don't have a battery backup, now's a good time to think about one — Northern Michigan spring storms knock out power, often right when you need the pump most.

3. Check Your Outdoor Hose Bibs and Sillcocks

Outdoor spigots are among the most freeze-vulnerable fixtures on any Northern Michigan home. Most modern homes use frost-free sillcocks, but "frost-free" only works if the hose was disconnected before freeze-up. If someone left a garden hose attached last fall, there's a real chance the sillcock froze, even if it's the frost-free type.

To check: turn the outdoor faucet on fully and let it run for 30 seconds. Watch for good steady flow. Then go inside and look near where the pipe enters the wall or passes through the rim joist — if there's dampness or dripping inside when the exterior faucet is running, the pipe likely cracked and is leaking into the wall cavity. That needs to be fixed before you start using the hose regularly.

Also look for any outdoor spigots that drip constantly even when fully closed. The washer inside may have cracked during the freeze. These are inexpensive repairs, but a dripping hose bib can waste thousands of gallons over a summer if left alone.

4. Give Your Water Heater a Spring Check-Up

Water heaters work harder in winter. If yours runs on well water with any mineral content — which describes most homes outside the city in this part of Michigan — sediment builds up in the tank over time, and winter's higher demand accelerates wear on the heating element and thermostat.

Spring is a good time to flush the tank to clear out sediment. Attach a hose to the drain valve at the bottom of the tank, run it to a floor drain or outside, shut off the cold supply, and drain until the water runs clear. It takes about 20–30 minutes and can meaningfully extend your tank's life.

While the tank is draining, visually inspect the area around it. Look for rust streaks, moisture around the base, or corrosion on the inlet and outlet fittings. Check the pressure relief valve — it should have a small discharge pipe running down toward the floor, and it should feel secure. If the valve looks corroded or was never tested, have a plumber look at it.

If your water heater is more than 10 years old and you're starting to see any of these signs, spring is a good time to evaluate replacement before it fails on a cold night in October.

What to Handle Yourself vs. What to Call a Plumber About

You can do the walk-through, run the sump pump test, and flush the water heater yourself. But if anything looks off — a pipe that's cracked, a sump pump that won't trigger, a hose bib that's dripping inside the wall — those are jobs for a licensed plumber.

The same goes for low water pressure throughout the house, discolored water, or any fixture that's been acting up since January. These issues don't usually fix themselves, and in Northern Michigan, waiting until summer means you're waiting in a longer queue. Spring is the right time to get ahead of it.
