State guidance for Missouri
For faucet & sink repair in Missouri, prepare cabinet access, shutoff condition, hole pattern, supply connections, trap, and countertop fit. Confirm the inspected scope, credentials, permits, inspections, exclusions, and restoration responsibility before authorizing work.
Credential verification
Missouri does not issue a single statewide plumbing license; plumbers are licensed and regulated locally by individual cities and counties. State law (Revised Statutes of Missouri, Chapter 341) sets baseline qualifications and, under RSMo 341.010, requires master and journeyman plumbers working in cities or towns of 15,000 or more inhabitants to first obtain a local certificate.
In St. Louis, the City's Board of Examiners of Plumbers and Drainlayers examines and licenses master plumbers, journeyman plumbers, and drainlayers, and St. Louis County runs its own Board of Plumbing Examiners. Kansas City licenses plumbing contractors and tradespeople through its City Planning & Development department, so the right credential to verify depends on where the work is being done.
Permits and inspections
Permit and inspection requirements in Missouri are set locally and vary by city and county. In many jurisdictions a licensed plumber must pull the permit and the work is inspected, while rules for owner-occupied homes differ from place to place. Always confirm requirements with your local building or permitting department before work begins.
Relevant water context
Water hardness in Missouri varies by city and water system, and ranges from moderately hard to hard. Kansas City's utility, KC Water, reports an average hardness around 100 mg/L (about 5 to 6 grains per gallon), in the moderately hard range, while parts of the St. Louis region report harder water. Mineral scale from harder water can shorten water heater life and reduce flow in fixtures over time.

Faucet and Sink Repair in Missouri: FAQs
How do I prepare for faucet & sink repair in Missouri?
Document when the leak or flow problem appears and whether hot, cold, or drainage use changes it and prepare cabinet access, shutoff condition, hole pattern, supply connections, trap, and countertop fit. Ask the professional to confirm the inspected scope, credential, permit responsibility, and exclusions in writing.
Does Missouri guidance diagnose my faucet & sink repair problem?
No. State information helps with credential, permit, and planning questions. The cause, responsibility, and repair or project scope still need to be confirmed for the specific property.
Why does my faucet keep dripping?
A persistent drip is usually a worn washer, O-ring, or cartridge inside the faucet. These parts wear out with use. Replacing them typically stops the drip.
What causes low water pressure at one faucet?
Low pressure at a single faucet is often a clogged aerator or a partially closed supply valve. If pressure is low throughout the home, the cause is usually broader. Our low water pressure guide has more.
Is an under-sink leak urgent?
It is worth addressing soon. Even a slow leak under a sink can damage the cabinet and floor and encourage mold. Catching it early keeps the repair simple.
