The tank and drainfield do different jobs
EPA explains that a conventional septic tank separates solids from wastewater; liquid then moves to a drainfield, where the soil treats and disperses it. You may also hear the terms soil absorption field or leach field. Ask the provider to identify the component it is discussing so a tank, pipe or pump issue is not confused with work on the absorption area.
Describe what changed
Note where the issue appears, when you first noticed it, and whether it comes and goes. Describe what you can see or hear rather than deciding which component has failed. Photos taken from a safe, accessible spot may help you explain the location. Ask what the initial visit includes, what it costs and what findings you will receive.
Look at the whole system
EPA describes a septic inspection as a review of system records and components, including the tank, connecting pipes and drainfield. A repair recommendation should follow that evaluation.
- Gather available design, inspection and maintenance records.
- Ask which finding supports the recommended work.
- Request a written scope explaining what is included and excluded.
For an Ellensburg property
Keep your property location and parcel information with your records. Use Kittitas County Public Health’s onsite sewage resources to ask which county steps apply to the proposed work. The county resources page on this site explains where to start.
