The water service line from the street to your home is the single most important supply pipe on the property — and in Flint, many service lines are original copper, galvanized, or lead connections approaching or past 50 years of age. A failure leaves the home without water and requires prompt diagnosis and repair.

(614) 926-0273The water service line from the municipal water main to your home has two ownership zones: the city is responsible from the main to the curb stop (the shutoff valve typically located at the property line or curb). The homeowner is responsible from the curb stop to the house — including the pipe, the curb stop itself, and all connections inside the property.
Flint's lead service line replacement program replaced the city-side portion of service lines for many properties — but not the homeowner-side connection. If your service line's homeowner portion is copper, galvanized, or an original lead line not replaced by the city program, understanding its condition and ownership boundary is essential before agreeing to any repair scope.
Know the ownership boundary before authorizing repair: city is responsible to the curb stop; homeowner is responsible from the curb stop to the house.
With all fixtures off, the water meter is checked for flow — confirming whether a leak is on the homeowner side of the meter. Movement on the meter confirms a supply side leak requiring further diagnosis.
The service line is located using electronic pipe locating equipment. Acoustic leak detection narrows the leak to a specific section — minimizing the excavation required for repair.
The failed section is excavated, repaired or replaced. For severely deteriorated lines, full service line replacement from house to curb stop is more cost-effective than repeated spot repairs.
After repair, the line is pressure-tested before backfill. The city is notified if the repair work requires coordination with the curb stop. Water is restored and a written report is provided.
Flint's extensive lead service line replacement effort — conducted following the 2014–2015 water crisis — replaced service lines across the city over multiple years. The program focused on the city-side portion of lines (from the water main to the curb stop) and, in many cases, both portions. However, not all properties were served, and homeowner-side lead connections in some pre-1960 homes may not have been addressed.
If you are unsure whether your service line was replaced, the City of Flint's water department maintains records of replacements by address. A licensed plumber can also identify service line material at the house entry point — copper, galvanized, and original lead each have distinct visual identifiers. Knowing your service line material is essential for both water quality and repair-planning decisions.
