Septic Questions, Answered Straight
Pumping schedules, warning signs, real estate inspections, and what's changing with Washington septic law — no jargon.
Most residential tanks need pumping every 3–5 years, depending on household size, tank capacity, and whether you run a garbage disposal. We'll check your tank's condition and tell you honestly what interval makes sense for your household — not a generic number.
Slow drains or gurgling pipes, sewage odor near the tank or in the yard, standing water or unusually green, spongy grass over the drain field, and sewage backing up into the house are the main signs. Call us if you notice any of these.
Yes — we take emergency calls every day except Saturday. If your alarm is going off or you have a backup, call (360) 956-0134 and a real person from our crew answers.
An On-Site Sewage (OSS) inspection checks your tank, drain field, and system components and produces the report that lenders, buyers, and county health departments often require before a home sale closes. We perform these across Grays Harbor, Thurston, and Lewis Counties.
Yes, and this matters if you're selling. Requirements aren't the same across our service area — some counties require an inspection or O&M report before a property with a septic system can transfer ownership, others don't currently mandate one at time of sale, and the specifics can change. The safest move is to call us with your address and closing date and we'll tell you exactly what's required for your property.
Washington has a new rule taking effect February 1, 2027 that will require a property-transfer inspection by an authorized third-party inspector for septic-served homes statewide, standardizing what's currently a patchwork of county-by-county rules. If you're planning to sell in the next couple of years, it's worth getting ahead of this.
Skip anything that isn't human waste or toilet paper — no wipes (even ones labeled "flushable"), feminine hygiene products, dental floss, cigarette butts, or cat litter. Cooking grease and coffee grounds should go in the trash, not the sink or garbage disposal.
No. The weight compacts the soil and can crush the pipes underneath, and concrete, asphalt, decks, or sheds over the field block the oxygen and evaporation the system needs to work. Keep the drain field clear of vehicles and heavy equipment.
A well-maintained system typically lasts 20–30+ years or more. Neglect — skipped pumping, driving on the drain field, flushing the wrong things — is usually what shortens that lifespan, not age on its own.
We quote every job based on what we actually find on-site rather than publishing flat rates, since tank size, access, and the real problem vary a lot from property to property. Call us and we'll get you a straightforward quote — no pressure to do work you don't need.
Grays Harbor, Thurston, and Lewis Counties — roughly 50 miles from our Aberdeen headquarters. See our Service Areas page for the specific cities and towns.
Yes — Bolan Septic Service is licensed, bonded, and insured in Washington State, and OSS certified.
We don't recommend relying on additives as a substitute for regular pumping. There's no substitute for having your tank physically pumped and inspected on schedule.
Stop using water in the house — toilets, sinks, showers, laundry — until we arrive. Keep people and pets away from any standing water in the yard, and call us at (360) 956-0134. If it's safe, locate your tank lids or risers so our crew can get to work faster.
