Faucet and Sink Repair across Washington begins with the same useful question: Identify whether the fault is in the faucet, supply, sink seal, trap, or shared pressure system. State context can guide credential and permit checks, but it cannot diagnose a specific property.
A visible drip does not establish whether the faucet, shutoff, supply, sink, or drain connection has failed.

State guidance for Washington
For faucet & sink repair in Washington, 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
Plumber certification in Washington is administered statewide by the Department of Labor & Industries (L&I). For most plumbing work, hire an L&I-certified plumber, and you can confirm an individual's certification or a company's license through L&I's official Verify a Contractor, Tradesperson or Business tool.
L&I issues certificates including Journey Level Plumber (PL01), Residential (PL02), Pump and Irrigation (PL03), Residential Service (PL04), and Backflow (PL30), plus an entry-level Plumber Trainee. Since July 2021, businesses must also hold a Plumbing Contractor license under Chapter 18.106 RCW, which requires a bond, liability insurance, and a designated certified plumber, so it is fair to ask who that designated plumber is.
Permits and inspections
Permit and inspection requirements are set locally and vary by city and county. In Seattle, for example, plumbing inside the building is permitted and inspected by Seattle-King County Public Health, while side sewers (the property owner's pipe out to the public main) are permitted through the Seattle Department of Construction and Inspections (SDCI); some jurisdictions allow owner-occupants to pull a homeowner permit. Always check your local building department or health authority first.
Relevant water context
Water hardness in Washington varies by source. Much of western Washington, including Seattle, draws soft surface water from sources like the Cedar and Tolt River watersheds, so scale is less of a concern there. Areas served by groundwater and wells, more common in eastern Washington and outlying communities, can run noticeably harder, where mineral scale shortens water heater and fixture life.

Faucet and Sink Repair in Washington: FAQs
How do I prepare for faucet & sink repair in Washington?
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 Washington 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.
