"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

Yes. A metal detector is one of the quickest and easiest ways to find your septic tank. However, metal detectors can be too expensive (costing upward of $300 in some cases), and not everyone has a metal detector just lying around. If that’s the case for you, you can also take a long metal rod and poke it into the ground at regular intervals until you hit something—likely your septic tank lid.

Many variables, such as home size, type of engineered system, the material used, soil conditions, and water usage, dictate how long your system will last. On average, most homeowners find that their system lasts 15 to 20 years, though it’s not unheard of for them to last up to 40 years with annual and preventative septic maintenance.

All municipalities in the U.S. require a permit for septic tank installation or septic system alteration, and the permit will usually cost between $450 and $2,500. Some municipalities also require permits for septic system repair. You’ll either need to contact your local building department or your septic tank company to ask if this is necessary before carrying out the work. Permits are not typically required to have your septic tank pumped, so provided your septic company is licensed, you can move forward with the work as needed.

With proper maintenance, most types of septic systems—including mound, evapotranspiration, and constructed wetland systems—can last up to 40 years. To keep your system running as long as possible, follow basic septic tank upkeep guidelines, like pumping your septic tank every three to five years and only flushing human waste and toilet paper.

Yes, experts handle manual pumping, chemical flushing, and equipment use properly, ensuring thorough cleaning and legal compliance with disposal regulations.
