The Hidden Problem
Your Water Line
Is Underground.
The Damage Isn’t.
Most homes in Clermont, Hamilton, and Brown County were built when galvanized steel was the standard for water supply lines. That pipe is now 50 to 80 years old — past its reliable service life — corroding from the inside out, narrowing with mineral buildup, and failing under Ohio’s freeze-thaw cycles. You can’t see it. But it shows up as rust-colored water, pressure that keeps dropping, and a water bill that climbs for no apparent reason.
In Hamilton County, Greater Cincinnati Water Works has identified tens of thousands of lead and galvanized service lines still supplying homes built before the 1960s. Ohio ranks second in the country for lead service lines in homes. If your house was built before 1960 and you’ve never had the line replaced, you may not know what material is bringing water into your home right now.
- Unexplained spike in your water bill
- Low or dropping water pressure throughout the house
- Rusty, discolored, or cloudy water from the tap
- Wet spots or soggy patches in the yard without rain
- Sound of running water when all fixtures are off

Common Questions
Water Line FAQ
The five main warning signs are: an unexplained increase in your water bill, low or dropping water pressure throughout the house, rusty or discolored water from the tap, wet spots or soggy patches in the yard when there has been no rain, and the sound of running water when all fixtures are shut off. Any one of these warrants a call — more than one at the same time means you likely have an active problem underground.
Yes — for Hamilton County homeowners served by GCWW, the utility now covers the full cost of replacing the lead service line from the street to your water meter. Homeowners are still responsible for any lead or galvanized pipe inside the home beyond the meter. If you’re not sure whether your home has a lead line, visit lead.mygcww.org or call GCWW at 513-591-7700 to check your address. FlowMax handles the private-side plumbing work that GCWW doesn’t cover.
It depends on the material. Copper typically lasts 50 or more years. PEX, used in newer installations, is rated for 50-plus years under normal conditions. Galvanized steel, which was the standard in homes built before the 1970s, has a realistic service life of 40 to 50 years and is often already past it in many SW Ohio homes. Orangeburg and lead lines are well past any reasonable lifespan. If your home was built before 1970 and still has the original water line, you are likely overdue for an inspection.
Galvanized steel pipe is iron pipe coated in zinc, standard in homes built between roughly 1900 and 1960. Over time, the zinc coating erodes and the steel beneath corrodes from the inside out. This creates rust buildup that narrows the pipe, reduces water pressure, discolors the water, and eventually leads to leaks or full failure. Galvanized steel is not always repairable — once the corrosion is extensive, replacement is the right call. GCWW now classifies galvanized steel service lines alongside lead as “requiring replacement.”
In most cases, the water utility (GCWW in Hamilton County, Clermont County Water Resources in Clermont County) owns and maintains the water main in the street. The service line from the water main to your home — including the meter — is generally the homeowner’s responsibility. This means leaks, breaks, and deterioration in that stretch are on you to repair. The exact boundary varies by location, so if you’re unsure, call your utility first and then call FlowMax to handle the private-side work.
Backflow testing verifies that your backflow prevention assembly — a device that stops contaminated water from flowing backward into the public water supply — is functioning correctly. In the Cincinnati area, annual testing is required for many commercial properties, irrigation systems, and some residential properties with cross-connection risk. A licensed tester inspects the device, records the results, and files the report with the water utility. FlowMax is licensed to perform and certify backflow tests across all three counties.
The most reliable DIY check: turn off every fixture in the house and check your water meter. If the meter is still moving, water is flowing somewhere — and if nothing is on inside, it’s underground. Soggy or unusually green patches in the yard, low pressure, and a rising water bill are all secondary signals. Underground leaks can run for months without being obvious above ground, which is why a pressure test and line inspection is the only way to confirm and locate the problem accurately.
