Seasonal PrepUpdated June 16, 2026
Rusty or discolored water coming from your tap is hard to ignore. Around Matteson, we see this issue most often in older homes with galvanized supply lines or aging water service pipes. With so many houses here built 50 to 70 years ago, this is a common problem, especially after long, cold winters or heavy rainfall.
Why Older Matteson Homes See Rusty Water
Many neighborhoods still have galvanized steel or even cast iron water lines. Over decades, these pipes corrode from the inside out. That corrosion flaking off produces the brown or yellow tinge you see at the faucet. In some cases, the problem runs back to the main water line, which may be original to the house and starting to fail after years of freeze-thaw cycles under the clay soil.
Lake Michigan water itself is treated and safe, but water picks up minerals and rust once it enters aging pipes under your property or inside your walls. Heavy storms and soil shifting can also cause cracks, letting in more rust or even sediment from outside.
Warning Signs That Your Water Line Needs Attention
- Water with a reddish, orange, or yellow tint at taps
- Metallic taste or odor
- Staining in sinks, tubs, or on laundry
- Rust flakes visible in water or around aerators
- Sudden pressure drops or noisy pipes, especially after storms or deep freezes
- Discoloration that clears after running the tap for a minute (suggests pipe rust, not city supply)
If you notice several of these, especially after harsh winter weather, your supply line may need service. Corroded pipes can leak or break, making seasonal prep important for Matteson's older housing stock.
Common Causes Beyond the City Supply
While some discoloration can happen if municipal mains are flushed or serviced, persistent rust points to a problem closer to home. In the Southland, main culprits include:
- Galvanized steel supply pipes: Still common in mid-century bungalows and ranches, these pipes rust from the inside.
- Iron service lines: Sometimes original to the property and now approaching the end of their lifespan.
- Water heater corrosion: An aging anode rod in your tank lets rust build up and enter your hot water taps. Our water heater services can diagnose and fix this.
- Recent plumbing work or main breaks: Sediment can enter the system or get stirred up.
If you're unsure where the problem is coming from, professional leak detection and repair tools can pinpoint the exact source, whether it's a supply line under your lawn or a joint inside the wall.
Seasonal Risks for Water Lines in Matteson
Cold, snowy winters here mean pipes are at risk for freezing and bursting, especially where insulation is lacking or outdoor spigots weren't winterized. Heavy clay soils hold water, so thaw and freeze cycles shift pipes and can cause joints to fail. If you see rusty water after a cold snap, it may signal a break or leak underground that needs quick attention.
During spring and summer, heavy thunderstorms increase the local water table and pressure fluctuations. This stresses old pipes and can push rust or sediment into home plumbing. Staying ahead of these seasonal changes with timely water line checks can prevent bigger repairs down the line.
What to Do About Discolored Water
- Run cold water from the tap for several minutes to see if discoloration clears (this helps tell if it's your pipes or the city main).
- Check if the discoloration is in both hot and cold lines, if only from hot taps, your water heater may be the source.
- Remove and rinse faucet aerators to check for rust flakes or sediment.
- If water remains cloudy or rusty, call a licensed plumber for assessment. Our water line services include full supply line inspections and repairs.
- If you spot new leaks, damp spots, or pressure loss, ask about pipe repair and repiping options.
In many Matteson homes, the fix may be as straightforward as replacing a short section of old galvanized pipe. In others, it may require new supply lines all the way to the meter. Our crew has handled these jobs for decades and can recommend the right, code-compliant solution for your property and budget.
Prepping Your Water Lines for Changing Seasons
Before the deep freeze sets in, or once the spring storms start rolling through, take a few practical steps:
- Schedule a whole-home plumbing inspection to spot corrosion or weak joints before they become emergencies.
- Drain and insulate outdoor spigots, and check basement areas where lines run close to exterior walls.
- Have your water heater flushed annually to keep sediment and rust at bay, see our water heater services for details.
- Install pressure-reducing valves if you notice repeated high-pressure surges, which speed up pipe corrosion.
Proactive care matters, especially in neighborhoods with original infrastructure. If your home is one of Matteson's mid-century builds or sits on heavy clay soil, regular inspection helps you avoid bigger headaches down the road.
