Water Service Line Leak Repair in West Chester, PA
The service line is the pipe that carries water from the street into your house. It runs underground, so a leak can go unseen for months.
Why is my yard wet when it has not rained?
Water bubbling in the yard, a soft patch in the lawn, a sudden pressure drop, or a meter that keeps moving when nothing is on can all signal a leak in the service line. Because the pipe is buried, the first sign is often the water bill.
The question to settle early is where the leak is. It might be in the part of the line the utility owns, or in the part you do.
The three sections of a service line
A service line is not one pipe with one owner. Starting at the water main under the street, a tap and a valve connect to a pipe that runs to the curb, where a curb stop valve can shut off water to the house. From the curb stop, the line continues to the meter, which may be in the basement or in a pit near the street.
From the meter, the house side of the line carries water through the foundation to the main shutoff.
Responsibility changes along that path. The utility generally owns the main and the connection, and the property owner generally owns the part from a dividing point to the house. The dividing point differs by utility, so ask yours before assuming.

Aqua Pennsylvania and the meter
Aqua Pennsylvania supplies the West Chester system and lists its customer line as 877-987-2782. Aqua's 2025 report says a service line inventory is available at aquawater.com/leadmap.
If the leak is on the street side of the meter, report it to Aqua. If it is on the house side, the repair is generally the owner's, so a plumber should document where the leak is before work begins.
What affects the price

A bill that has risen with no visible cause is covered in the meter test for unexplained usage. Detection methods are described in the process of tracing a hidden leak, and trenchless options in trenchless repair.
Protect yourself before any digging
Old service lines may be lead, galvanized steel, copper or plastic. If yours is being replaced, ask the plumber what the new pipe is and what the old one was.
What to do if you see water in the yard
Do not dig. Close the main, note the spot and call 811 before any excavation, as the law requires. Water line materials should meet NSF/ANSI 61 standards for drinking water.
The township building at 1580 Paoli Pike can confirm which streets in East Goshen have public water and sewer. That matters when you decide who owns a leaking line.
The line between the water main and the meter runs under older streets in the borough, where Aqua Pennsylvania has supplied water since 1998. A wet patch near the curb or a sudden pressure drop is the usual sign.

Yes, the 24/7 line is open.
