Frequently Asked Questions
What does a septic pumping service usually include?
A typical pumping visit usually involves locating the tank, opening the lids, measuring the sludge and scum layers, and pumping out the contents into a truck for disposal. Many contractors also rinse the tank walls and check the baffles and inlet and outlet pipes while the tank is open. Ask what the quoted price covers, since some providers charge extra for digging or riser work.
Should I get a septic inspection when buying a home in Seattle?
An inspection is often worthwhile when buying a home, because it can reveal the tank condition, the drain field, and whether the system was maintained. A basic pumping visit is not the same as a full evaluation. Ask the seller for pumping and service records, and consider having a qualified local professional assess the system before you close.
Who do I contact about septic system rules near Seattle, Washington?
Septic rules in and around Seattle, Washington are handled at the local level, and requirements can differ between jurisdictions. For permits, inspections, or questions about your system, contact the county or city office that oversees onsite sewage, or ask a qualified local septic professional. They can explain what applies to your property.
