"I had a drain clog that was becoming a real headache, and Sewer Surgeons took care of it quickly and professionally. The technician was friendly, showed up on time, and explained what was going on without making it complicated. The price was fair, and there were no surprises. The whole process was made easy and overall I would recommend them to anybody in a heart beat."

"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."

"Charles is perhaps the most friendly and professional contractor I have ever hired. He removed an old septic tank and replaced it with a new one along with a better leaching field. He then repaired and seeded the lawn where the work was done. I also had him remove a shrub and deliver stones for some landscape improvement. A genuinely nice person as well. I cannot recommend him enough."

Septic Tanks FAQs, answered by experts

With so much available information about the ecological effects of cesspools (and their general unpleasantness), it begs the question: Are cesspools legal? In short, sort of. Large-capacity cesspools that serve more than 20 people are completely illegal countrywide. Existing, smaller cesspools are generally allowed as long as they’re not actively polluting. However, new cesspools are illegal to build in all 50 states and Puerto Rico, and many states offer programs to help homeowners with the costs of updating cesspools to modern septic systems.

Most well pump pressure switches have a factory setting of 30 to 50 PSI. There’s some flexibility with this if you’d like a lower or higher water pressure, but remember that it should sit 2 to 3 PSI above your well tank’s general pressure setting.

The inside of your pressure switch cover will usually indicate minimum and maximum settings—going below and above the numbers might damage your well pump.

Most septic tanks can handle two to three loads of laundry per day, or a weekly total of between seven and 10 loads. Although septic systems do require homeowners to be somewhat careful with their plumbing systems—for instance, it’s not a good idea to flush a bunch of toilet paper all at once—they can still handle fairly heavy use.

An outdoor water valve typically has a round or oval handle that you can turn to control the water flow. It may be located in a protective box or pit near the property line, where the main water line connects to your house.

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.
