Do this now: a leak or backup in a Kansas City home

1. Close the main water shutoff. KC Water maintains the line only up to the curb box; past that, the pipes are yours.
2. Water near outlets: shut the breaker only if you can reach it from a dry spot.
3. Smell gas? Leave the house and call your gas utility or 911 from outside.
4. Main break in the street, no water or low pressure, or a sewer backup: call 311. KC Water inspects and cleans the public main for a property with backups.
5. Frozen pipe: keep the faucet open and warm it with a hair dryer or heating pad, never an open flame (American Red Cross). See frozen pipes.

Licenses and permits for plumbing in Kansas City

Missouri has no statewide plumbing license; Kansas City licenses plumbers itself. City Planning and Development issues Journeyman and Master Plumber licenses, along with Gas-Fired Appliance, Mechanical and Pipe Fitting licenses, and its contractor licensing page lets you search licensed contractors. Permits are required before most plumbing work, though replacing a component part of an appliance is exempt. An owner who lives in a single-family home and does the work personally may pull the permit; everyone else must be a licensed contractor. Permit fees are based on the total cost of construction. Permits Division: 816-513-1500.

KC Water: what the City fixes and what you fix

KC Water repairs leaks on water meters and public mains; leaks inside the house, in sprinklers and in the service line are the homeowner's job. KC Water gives free dye tablets to check a toilet for leaks (816-513-1313, Option 1) and takes leak adjustment requests through its customer ePortal, though it publishes no terms for them. KC Water partners with Service Line Warranties of America on an optional service line plan and says those mailers are legitimate. KC Water's 2024 water quality report lists carbonate hardness of 140 mg/L. See leak detection if the bill jumped and you cannot find the source.
