"Went extremely fast and easy. Drain clogged for a week no matter what I tried. Uriel came about 10 minutes after the phone call, and was out 10 minutes later. Mask on, and made sure he made no mess. Would highly recommend!"

"I had a problem at my vacation rental. John contacted me quickly when I posted my problem for quotes online. I had a failing septic. It was no longer draining. John came out and accessed the the situation and based on faulty drawings I supplied, he gave me an estimate for repair. I agreed to the figure. When he discovered that the drawings were wrong and he only had to dig up 5 feet (not 14) between the septic tank and the seep box he lowered his estimate. You can't ask for more honesty and fairness. He and his worker completed the job in less than 2 days. Hire him!"

Septic Tanks questions, answered by experts

Start by finding the septic tank, marked by an access lid near your home. From there, the drain field extends outward in a series of trenches. Look for greener, lusher grass, as drain fields promote plant growth due to moisture and fertilizer. You can also check property records, use a soil probe to detect damp soil, or hire a septic professional with ground-penetrating radar equipment to map the drain field’s location.

There are three layers of wastewater in a septic tank: scum (solid waste that floats to the top of the wastewater), liquid (the relatively clean liquid wastewater in between the two other layers), and sludge (solid waste that falls to the bottom of the wastewater). The buildup of sludge is one of the main reasons septic tanks need to be pumped. If the tank is more than 1/3 of the way full with a combination of sludge and scum, it’s time to call a pro for pumping.

To keep roots from growing into a septic tank. However, there are other steps you can take if existing tree roots are getting close to your septic tank. For one, you can install root barriers, which physically block roots from reaching your septic tank. You can also use chemical solutions in your yard or plumbing system to deter root growth.

Yes, septic tank companies must be licensed in most states and municipalities to perform services like installation, alteration, repair, and pumping. Since laws vary by location, it's crucial to check local requirements.

Hiring an unlicensed professional can lead to poor work, code violations, and significant fines. Always verify that your chosen company is properly licensed and fully insured to avoid liability. You can use tools like Angi’s contractor licensing search to check a pro's credentials.

It's also helpful to understand the difference between licensing and certification. A license is a legal requirement to operate, while certifications are voluntary. Credentials like the “Angi Approved” badge indicate that a business meets extra standards, such as passing a background check and maintaining a high rating.

The purpose of a septic tank is to allow solid wastes to separate out of the wastewater using time, gravity, and other natural biological processes. If your septic tank is too small, it might be overwhelmed by solid waste and unable to accomplish this task—and if it’s far too large, there won’t be enough liquid in the tank to nurture the necessary bacteria to aid in the breakdown process.
