"We needed the septic system repaired, tested and certified for sale of the home. King County Septic explained things in a simple and straightforward manner, agreed on a price, and performed the work quickly and efficiently. They were very responsive to our concerns and got back to us quickly to answer questions that we had along the way."

"The technician emptied the freezer, which was in the basement, to work on the part that needed repair. Then he neglected to put anything back into the freezer, including a turkey I had bought for Christmas and a rack of ribs. Two days after he left, I went out of town for two weeks. The turkey actually exploded and spewed its liquid all over everything, which had to be discarded. I let AHS know and they couldn't even bother to call me or follow up on this. I'm considering not renewing my contract with them because of the quality (or lack thereof) of many of the providers they send."

Septic Tanks FAQs, answered by experts

There should be a red button or an on/off switch on or in your box. Press the button or flip the switch, then turn it back on by doing the same action again. If this doesn’t work, reset the breakers inside the box by flipping them off and back on again. After this, your alarm should stay off if there’s nothing wrong with your system. However, if the alarm is still sounding and there’s still a red light on, it’s time to call a pro for a diagnosis.

Yes. Amongst the four most common types of septic tanks—plastic, fiberglass, concrete, and steel—those made of concrete are the most expensive. This is the case for a few reasons, including the fact that they’re very heavy, so pros have to use specialized equipment to install them. However, they’re also incredibly durable, making the price worth it if it’s in your budget.

To determine the right size for your submersible well pump, find your well depth, water demand, and well casing diameter. The pump should match your well's specifications and meet or exceed your drawdown and pressure requirements. 

For precise sizing, make sure to research the different well pump sizes, consult the manufacturer's recommendations, or seek guidance from a professional well pump installer.

French drains, sump pumps, and exterior waterproofing systems are common options. Choose one that best suits your property’s needs.

Expect to take at least a day to drill your own well by hand. For a 500-foot well, this could take even longer, depending on the makeup of the soil and the terrain you are drilling through. Other factors include your physical strength and overall fitness level and the weather conditions you’re working in.
