"I hired them because they said they could pump my septic AND snake my drain. They did pump my tank very nicely, they were available when I needed them, and they were able to identify a problem immediately. However, what they meant by snaking the drain is that they could send another person out for an additional fee to snake the drain. I was also only quoted for the pumping and not the snaking so I ended up paying double what I thought I was going to pay. I also found out AFTER the first payment/job that they had a military discount so that was a little disappointing, but I am very grateful that it was applied to the second payment/job."

"We needed repairs from our septic tank to the distribution box and they were recommended to us. They did a great job explaining where the likely issue was and gave us a very fair quote. When it came time to do the job, he ran into a couple of unexpected old cable lines and irrigation lines and carefully worked around them. I would definitely recommend them for anyone looking for septic or excavation work."

Septic Tanks questions, answered by experts

Mound systems can fail if foreign objects are flushed into the septic tank, the septic tank is backed up with solid waste (sludge), if wastewater floods or seeps from the mound, or if any part of the system is clogged. To prevent this, only flush toilet paper and your normal “business” down toilets, and get a septic inspection at least yearly.

Yes, shower water goes into the septic tank. Shower water is a type of greywater, and in fact, all water used in a home with a septic system—including water from sinks, toilets, the dishwasher, and the washing machine—drains into the tank. When shower water enters the tank, debris like soap and hair travels with it. The solid debris sinks to the bottom to become sludge, while soap residue joins the scum layer at the top. The remaining water is treated in the tank before moving to the drain field for further treatment and dispersal. It is important to avoid putting oil or harsh chemicals down any drain, as they can cause clogs or disrupt the beneficial bacteria required for proper wastewater management in the septic system.

The smallest septic system available for purchase typically includes a 750-gallon tank. However, the smallest size you can legally install is determined by local regulations, and many areas require a minimum capacity of 1,000 gallons. The cost to install a small septic system generally ranges from $2,910 to $13,900. Before proceeding, it is essential to check with your local health department or consult a local septic professional to confirm the minimum legal requirements in your area.

According to the Environmental Protection Agency (EPA), septic tanks must be located a decent distance from places subject to flooding or surface ponding. Additionally, septic tanks should be installed on level ground so that the waste can properly settle in the tank. Most tanks are located 10 to 20 feet away from the home. More specific requirements vary by location, so call a local septic pro or your local health department for more information.

Unlike an urban sewer system that runs wastewater into a central drainage system, septic tanks are a house-by-house system. They are the ultimate destination for all your house’s wastewater—from bathtubs, showers, sinks, toilets, and washing machines. Wastewater flows into a tank buried in the ground outside your home, and then water runs from the tank to a drainage field using sloped pipes.
