Water service line repair in Kansas City
Updated · Editorial team; not yet technically reviewed
Short answer
In Kansas City, Missouri, KC Water maintains the water mains up to the curb box, and the property owner is responsible for the service line from the curb stop to the house. City Ordinance Section 78-22 requires owners to keep that line free of leaks, and KC Water has partnered with Service Line Warranties of America on optional coverage.
What's different in Kansas City
KC Water maintains repairs on water mains up to the curb box on private property; from that point on, repairs are the property owner's responsibility. [1]
City Ordinance Section 78-22 states that the owner of the premises shall maintain the water service against leakage from, but not including, the curb stop or first shutoff valve to the premises served. [1]
KC Water has partnered with Service Line Warranties of America to offer optional repair coverage, since service line repairs are often not covered by standard homeowners insurance. [2]
Where your responsibility starts
The curb stop (or curb box) is the dividing line. Everything from that valve to your house, including the pipe under your yard and through the foundation, is yours to keep leak-free under Ordinance 78-22. Knowing where your curb box is also helps in an emergency, since it's where water can be shut off outside.
Signs your service line is leaking
- A wet or sunken spot in the yard between the curb and the house, especially in dry weather.
- A water meter that keeps moving with all fixtures off.
- A sudden drop in water pressure.
- Higher bills without higher use. See high water bill.
Kansas City freezes and older lines
Kansas City winters can freeze shallow or poorly insulated service lines, and many older homes still have galvanized or other aging pipe. When a line fails repeatedly, replacement is often more economical than repairs; trenchless methods can avoid tearing up the yard. See water line repair.
