State guidance for Washington
For sewer camera inspection in Washington, prepare cleanout access, line cleaning, camera reach, locating, recording, and written findings. 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.

Sewer Camera Inspection in Washington: FAQs
How do I prepare for sewer camera inspection in Washington?
Document whether recurring backups, purchase planning, or a proposed repair requires documented line condition and prepare cleanout access, line cleaning, camera reach, locating, recording, and written findings. Ask the professional to confirm the inspected scope, credential, permit responsibility, and exclusions in writing.
Does Washington guidance diagnose my sewer camera inspection 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.
What is a sewer camera inspection?
A plumbing professional feeds a small, waterproof video camera on a flexible cable through your sewer or drain line, usually starting at a cleanout. The live video shows the inside of the pipe in real time, so the cause and location of a problem can be seen rather than guessed at.
When is a sewer camera inspection worth it?
It is most useful when clogs keep coming back, when you are buying a home and want the buried sewer line checked, or when you suspect roots, a crack, or a collapse. It is also a good way to learn the condition of an older line before committing to any repair.
What can a sewer camera find?
A camera can reveal root intrusion, cracks, broken or collapsed sections, separated joints, bellied or sagging stretches, grease and scale buildup, and blockages. It can also show the pipe material and general condition, which helps a professional recommend the right fix.
Can the camera tell where the problem is in my yard?
Yes. Many cameras include a transmitter, and the professional uses a locator above ground to mark the exact spot and depth of a problem. That makes any repair far more precise and helps avoid digging in the wrong place.
Should I get a sewer camera inspection before buying a house?
It is often a smart step, especially for older homes or properties with large trees near the line, because the buried sewer is not covered by a standard home inspection. Finding a problem ahead of time can save you from an expensive surprise after closing.
