Understanding the water supply system in older Pottstown homes
The water supply path to your home has two ownership zones. Pennsylvania American Water owns and maintains the water main in the street and the service line from the main to the curb stop valve, which is typically at the property line or near the sidewalk. The homeowner owns the service line from the curb stop into the home and is responsible for maintaining and repairing that portion.
In Pottstown's older housing stock, that homeowner-owned portion is often galvanized steel or lead. Galvanized steel service lines installed before 1960 are now 65 or more years old; many have developed significant internal corrosion that reduces water pressure and can eventually fail. Lead service lines are a health concern regardless of their physical condition; see our lead service line replacement page for detail on that specific issue.
The interior supply pipe from the meter into the home and throughout the house is also homeowner-owned. Galvanized supply pipe inside the walls of pre-1950 Pottstown homes corrodes over decades, restricts flow, and eventually develops leaks at joints and fittings. When the supply problems are widespread throughout the home rather than localized, whole-home repiping may be the appropriate solution; see our repiping page.
Water line breaks: signs and response
A water main or service line break has specific indicators that distinguish it from a supply line problem inside the home. Sudden pressure loss throughout the entire house (not just at one fixture) while all indoor valves are open suggests the supply is disrupted before it reaches the meter. A wet or saturated spot in the yard along the path from the street to the foundation, a muddy depression or crack in the driveway, or water flowing in the gutter with no recent rain are physical signs of an underground break.
If PAW's main in the street has failed, the utility is responsible for the repair. We can help you confirm whether the break is in the utility-owned section or the homeowner-owned section by testing pressure at the meter and at the curb stop. If the break is in the utility section, we contact PAW on your behalf. If it's in the homeowner section from the curb stop in, we handle the repair.

Frequently asked questions
What is the difference between a service line and a water main?
The water main is the municipal pipe in the street owned and maintained by Pennsylvania American Water. The service line runs from the main to your home's water meter. PAW owns the portion from the main to the curb stop valve; the portion from the curb stop into your home is the homeowner's responsibility. We repair and replace the homeowner-owned section.
My water pressure dropped suddenly throughout the house. Could it be a water line break?
Sudden pressure loss throughout the house (not just one fixture) can indicate a service line or main break. Look for a wet or soft spot in the yard along the path from the street to the foundation, or a water meter that registers flow when all household valves are closed. Call us to diagnose, and we'll determine whether the break is in the homeowner-owned or utility-owned section.
How long does a galvanized steel water service line last?
Galvanized steel service lines typically have a functional life of 40 to 60 years before internal corrosion reduces pressure significantly or the pipe fails. Most galvanized service lines still in service in Pottstown were installed before 1960, meaning they are past or approaching the end of that range. A galvanized line that ran downstream from a lead main may also carry lead deposits in its internal scale.
Can you repair a section of water line rather than replacing the full run?
Yes. For a localized break or pinhole leak, a section replacement or repair sleeve is appropriate. For widespread galvanized corrosion or a lead service line requiring full replacement, the full run from curb stop to meter is the better approach. We assess the full line condition before recommending repair or full replacement.
