"This family owned and operated company went way beyond what customer service and expertise I had expected to replace my old failed septic tank. They explained all steps they needed to bring my old system up to code. They stayed in contact with me almost daily and took pictures when I was unavailable to be home and see their progress! They even leveled my sloping backyard to make it more aesthetically pleasing and replanted all the grassy areas. After comparing many companies costs, and type of system I'd need for this service, i am very pleased with the quote LED presented to me, the work time to complete the job, and the final results! Thank you LED team! It's nice to see that a true honest work ethic is still in vogue! Thanks Derek and Dad! You all did a great job! I'd highly recommend!"

"The plumber said my backed up pipes were from the septic system needing to be cleaned. Called Max Haas Company and they were able to get someone out the same day. They dug down to the tank top and cleaned the tank. Unfortunately, that didn't solve my plumbing problem but their service was excellent. Would definitely use them again.

"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."

"Had the service line from our house to the septic (under the driveway) replaced as it had pulled away from the tank (which we later found was due to the original installer not doing it right). They removed the concrete, replaced the service line and replaced the concrete after. They came out quick for a quote, used a camera to inspect the line (which was nearly half of the cost of all other quotes to run a camera) and found the damaged pipe. Was put on their schedule quick (luckily they had an opening so soon) and they performed quality work. Communication was great from start to end. I can't say enough good things about this company. A+ Service"

Septic Tanks FAQs, answered by experts

A septic system's lifespan typically ranges from 15 to 40 years, with a common average of 20 to 30 years. The longevity heavily depends on the tank's material, maintenance diligence, and usage habits. With proper care, lifespans can reach the upper end of this range.

Lifespan by Tank Material:

  • Concrete: 20 to 40 years

  • Plastic or Fiberglass: 30 to 40 years

  • Steel: 15 to 20 years

To maximize your system's lifespan, follow these maintenance best practices:

  • Regular Pumping and Inspections: Have the tank pumped every three to five years and schedule professional inspections regularly.

  • Mindful Usage: Only flush human waste and toilet paper. Avoid putting items like cat litter, paper towels, cigarette butts, fats, grease, oils, or coffee grounds down your drains.

  • Avoid Chemicals: Do not pour harsh chemicals into the system.

  • Water Conservation: Reduce the amount of wastewater your system has to process.

  • Protect the Drain Field: Avoid driving or building heavy structures over the drain field area.

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.

Several signs can indicate a faulty well pump pressure switch. These include your pump running continuously, the pump not turning on at all, or a sudden and complete loss of water. Other symptoms are weak water pressure or an erratic, unpredictable water flow from your fixtures. If you notice these issues, the pressure switch may be the cause. Testing the switch can help diagnose the problem. A faulty switch will likely need to be repaired or replaced. If the issue is more complex, it's best to consult a professional well technician to ensure your water supply is restored correctly.

Recognizing signs of a failing septic system is crucial to prevent costly damage and health hazards. Foul odors in and around your home, slow drainage in sinks and toilets, or gurgling noises in plumbing fixtures can indicate problems with drainage. Lush, green patches of grass near the drain field or wastewater pooling on the ground are alarming signs that may indicate a leak in the system. If you notice any of these symptoms, it's vital to address them promptly to avoid more extensive and expensive issues.

You can add three rotten tomatoes or 1/4 ounce of yeast to your septic tank to speed up the decomposition of sludge. You can add the tomatoes by way of your garbage disposal and the yeast by way of your toilet. You can do either of these additives once every three months as needed.
