What Is Septic Pumping?

Septic pumping is the process of removing waste from a septic system by pumping it out via a hose. The hose sucks the solid waste and wastewater into a waiting truck, which then hauls it away for safe disposal, leaving you with a clean tank that’s ready to be filled again.

Septic pumping is a routine part of septic maintenance – and arguably the most important. It should be performed regularly, but your interval may vary depending on the specs of your tank and your household usage pattern. If your septic tank fills up and causes an issue like a backup sooner than expected, you may need immediate or emergency septic pumping services.

A worker in protective gear examines an open septic tank outdoors. Routine inspections like this can ensure the longevity of your septic system. Schedule a service with Puget Sound Septic to keep your system running smoothly.

Why Is Routine Septic Tank Pumping Important?

When a septic system is operating efficiently, you barely notice it. When a septic tank suffers a breakdown or an emergency, it can be catastrophic. Routine septic pumping is the best way to ensure you never have to protect your property and your wallet. 

Here’s why regular septic pumping is so important:

  • Protects Your Drainfield: Prevents solids from escaping the tank and clogging your soil — the most common cause of total system failure.
  • Prevents Backups: Keeps waste flowing away from the house and prevents sewage from surfacing in your yard or tubs.
  • Protects Water Quality: Keeps harmful pathogens and nitrogen out of your well water and the local environment.
  • Saves Money: A pump-out every few years prevents a $20,000 replacement down the road.
  • Maintains Property Value: A documented service history is a requirement for any home sale in the Seattle area.
  • Extends System Life: Regular septic tank maintenance can extend the lifespan of your tank and all of its components.

How Often Should a Septic Tank Be Pumped Out?

We recommend septic tank pumping at least once every two to five years. Yes, that’s a wide range – it all comes down to how much wear you’re putting on the tank. If you have a new tank, live alone, and don’t use a garbage disposal, you’re probably fine waiting until every four or five years. Whereas if there are several of you living in the same dwelling serviced by an aging septic tank, you should get it pumped every couple of years. It comes down to four main factors: septic system age, septic tank size, household size, and whether you use a garbage disposal. Garbage disposals put a lot of strain on septic tanks. If you’re not sure, we recommend getting a professional septic tank inspection.

How Do I Tell If My Septic Tank Is Full?

If your septic tank is full, you will most likely notice some of these warning signs:

  • Slow Drains: Sinks, tubs, and showers across the entire house are sluggish.
  • Gurgling Pipes: Bubbling or “glugging” sounds in your plumbing after a flush.
  • Foul Odors: Persistent sewage or “rotten egg” smells near the tank or drains.
  • Lush Grass: A patch of grass over the drainfield that is greener or thicker than the rest of the lawn.
  • Soggy Ground: Standing water or muddy spots in your yard when it hasn’t rained.
  • Sewage Backup: Dark water backing up into your lowest-level drains or toilets.
A partially open septic tank lid reveals murky wastewater inside the tank. Regular septic maintenance can help prevent overflow and backups. Contact Puget Sound Septic for professional services.

Washington/Seattle Area Septic Pumping Rules

One important thing to keep in mind is that septic pumping can be performed by certified professionals only

A King County Certified pumper must perform all maintenance, inspections, and pumping; work performed by uncertified individuals will not be accepted by the county.

  • Gravity Systems: Must be inspected at least once every three years.
  • All Other Systems: (Pressure distribution, mounds, sand filters, and ATUs) must be inspected at least once every year.
  • Pumping Thresholds: Pumping is legally required when an inspection shows that solids (sludge and scum) occupy one-third of the tank’s total volume.
  • Time of Sale Requirements: Before selling a property, you must have a full system inspection performed by a certified professional. This report is now valid for one year from the date of inspection.
  • Online RME Reporting: All inspections and pump-outs must be digitally filed by your service provider to the Online RME database to be considered “in compliance” by the Health Department.
  • Safety Lock Requirements: All septic tank lids must be bolted, screwed, or otherwise locked to prevent unauthorized access or accidental entry by children and pets.

How to Prepare for Your Septic Pumping Service

Your Puget Sound Septic septic pumping technician will handle everything from start to finish, but in order to ensure your service goes as smoothly as possible, there are a few things you can do beforehand. Here’s what we recommend:

  • Locate the Lids: Mark your tank lids with a stake or flag so the technician can find them immediately. Not sure where your tank is? We offer septic locating services.
  • Clear the Path: Move vehicles, patio furniture, and debris away from the tank and the driveway.
  • Secure Pets: Keep dogs and other animals inside or in a separate area for their safety and ours.
  • Uncover the Lids: If your lids are buried and you don’t have risers, digging them out ahead of time prevents additional labor fees.
  • Provide Access: Ensure gates are unlocked and the technician has a clear path for the heavy vacuum hose.
  • Minimize Water Use: Avoid running the laundry or dishwasher right before your appointment.
