Seasonal PrepUpdated June 16, 2026
Low water pressure is a constant headache in many Homewood homes, especially as colder months approach and demand rises. Homes built decades ago often have supply lines that no longer meet modern needs. As your local plumbing crew, we've seen how an undersized water service restricts both pressure and flow, affecting daily life and sometimes putting your plumbing at risk when winter temperatures hit hard.
Why Older Homewood Homes Have Undersized Water Lines
Much of Homewood's housing stock was built 50 to 70 years ago, long before today's fixtures and appliances became standard. Builders often installed lead or galvanized steel service lines as small as 1/2 or 3/4 inch. These pipe sizes made sense when homes had one bathroom and minimal laundry or kitchen needs. Now, with multiple bathrooms, sprinkler systems, and water-using appliances everywhere, those old lines can't keep up.
Another problem is corrosion inside old galvanized steel. Over time, mineral buildup from Lake Michigan's moderately hard water chokes the pipe, shrinking the inside diameter even more. In winter, freeze-thaw cycles can stress these pipes to the point of leaks or bursts, especially if they're already weak or sludged up.
How to Spot an Undersized or Failing Water Service
- Noticeable drop in pressure when more than one fixture runs
- Shower runs cold if a toilet or washing machine kicks on
- Long delays in water heating (sometimes the water heater struggles due to poor inlet flow)
- Visible corrosion or outdated piping material where the supply enters the house
- Unexplained spikes in water bills, possibly pointing to leaks
If you are seeing any of these issues, it may be time to look at your main water line size and condition. For anything involving possible leaks, our leak detection and repair service can help you track down trouble spots before they escalate.
The Upgrade Process What's Involved
Upgrading a water line isn't just swapping out a pipe for a bigger one. In Homewood, clay-rich soils and flat property grades complicate digging and trenching. We start by sizing the new line for your current and future household needs, most homes benefit from at least a 1-inch copper or approved plastic service. For older homes with cast iron mains or clay tile sewer lines, careful planning is key to avoid other underground utilities and drainage features.
Once sized, the new service is installed from the municipal shutoff (usually at the curb) to your home's main valve. We coordinate with the water department for shutdowns and inspection, then test for leaks and proper pressure before backfilling. Afterward, you'll get a smooth flow and fewer worries in the dead of winter.
Why Upgrade Before Winter?
Homewood winters have frequent freeze-thaw cycles and subzero days. An undersized or aging line is more likely to freeze, especially if it runs along a shallow trench or against an exterior foundation. When pipes freeze and burst, it can mean major repairs, water damage, and weeks of disruption. Upgrading the supply line raises the odds your water keeps running even when deep frost sets in. Your plumbing system gets a fresh start with stronger connections and piping built to current code.
Winter is also when sump pump systems are put to the test, as melting snow and frozen ground push water into basements. Reliable supply helps with sump pump maintenance, especially since our region's clay soils can trap water near the foundation. Getting the water service right is one less thing to worry about when everything freezes up in January and February.
What About Other Outdated Plumbing?
If your main supply line is due for an upgrade, it's a good time to review all original plumbing. Old galvanized water lines inside the home may soon need replacement too, as corrosion and scale lead to future leaks or flow problems. Our pipe repair and repiping solutions cover everything from a single branch line to a full-house update.
Drainage is another common headache in older Homewood homes. Clay tile and cast iron sewer lines are known for root intrusion and blockages. If you see slow drains or backflow along with pressure issues, our drain cleaning and sewer line services can help keep your whole system flowing freely year-round.
Practical Steps for Homeowners
- Check exposed water supply pipes for diameter and material (look for steel or copper near your main shutoff)
- Ask your water provider for your current line size if you're unsure
- Watch for cold-weather warning signs, such as slow flow or odd noises at faucets
- Schedule a professional evaluation before winter sets in
- Upgrade aging indoor piping at the same time as the main line if possible
