Lockport's water comes from wells, and it is hard. Older sections have galvanized and cast iron pipe that has corroded for decades, and the clay and glacial deposit soils shift every winter, stressing sewer lines. We've been fixing these problems since 2002.

Lockport's Hard Water and What It Does to Your Plumbing

Among the hardest water in the Chicagoland region.

Lockport's water comes from wells, and it is hard. Scale coats water heater elements and cuts efficiency over time. Point-of-use filters handle taste and specific contaminants at one tap. Whole-home softeners treat calcium and magnesium at entry. Reverse osmosis removes a broader range of dissolved solids. We assess your water, home age and household first.

What Lockport Homeowners Should Know About Permits

The City of Lockport Building Department requires permits for most work beyond simple repairs: water supply lines, sanitary and storm sewer drainage, soil and waste lines, vent lines, gas lines and water heater replacements. Unpermitted work can complicate a sale and void a new appliance's warranty. We pull the permits and know what inspectors look for. Not sure about your project? Ask before work starts. An outdoor spigot replacement is a common permit-required job in Lockport's older homes.

Alvin KFeb 2026 · Google
In February of 2026 I used Leto Plumbing & Heating on two occasions. First for an emergency after hours weekend call when my sump pump line was frozen during our recent sub-zero weather. The second was a routine maintenance call to flush my hot water heaters. Both times the individuals that came out were pros who were friendly, knowledgeable and got the job done right the first time. Would highly recommend!

Leto Plumbing has been servicing the plumbing and HVAC in our homes for many years. Rick and Chris, father and son, are amazing in every way. They are reliable, neat, courteous, and knowledgeable in all areas of plumbing and HVAC. They go out of their way to rush out to our home for needed repairs and new work. They may not be “cheap”, but you can rest easy that their work is top quality and will give you peace of mind. TFK St. Charles

Very happy with the service received by Leto plumbing. Starting with phone call made, very nice and was able to get us scheduled next day. Chris, technician, was earlier than originally expected (which was great), he explained everything, was very courteous and timely. Extremely happy with service provided and will be calling Leto for any future needs.

Frequently asked questions

How do I know if my older Lockport home's pipes need replacement or just a repair?
Galvanized or cast iron pipe corrodes from the inside. Watch for low pressure with no blockage, discolored first-morning water, repeat leaks along one run and corroded joints. One failed section usually means repair. A compromised run is cheaper to repipe long-term.
Why do frozen pipes happen in Lockport winters and what should I do?
Hard freezes split copper or PVC in exterior walls, crawl spaces and garages. No water at a fixture during a cold snap? Shut the main at your meter and call us. A frozen pipe that hasn't burst is a fast fix. We answer at (815) 609-3150 at any hour.
What's the difference between a water softener, a whole-home filter, and a point-of-use system for a Lockport home?
A softener removes calcium and magnesium by ion exchange, protecting pipes and appliances from hard water. A whole-home filter handles a broader range of contaminants. A point-of-use system treats one tap only. Many Lockport homes run a softener at entry plus a kitchen filter.
How quickly can Leto Plumbing reach a Lockport home for an emergency?
We're based in Plainfield, a short drive away, and answer around the clock, not with a call center. For a burst pipe, active flooding or a frozen sump line in sub-zero weather, we dispatch as fast as conditions and call volume allow.
