"Mike and his team are extremely responsive and professional. From the first contact to final installation for a large, complex septic system, it only took 2 weeks including all the permit and inspection. We are really grateful for finding Septic Advisor through Angie's list and hired him for our project. We cannot be happier! Highly recommended! Will definitely hire Mike again for any future needs."

"Absolutely unbelievable service. They dropped what they were doing on a Saturday night to come out and fix our septic issue. They explained the issue and fix very clearly. Left the property looking great considering they had to dig into the septic tank. The responders were very friendly and took time to engage in conversation while still achieving their work in a very timely fashion. Not that I know much of the septic business, but the men seemed knowledgeable of their profession and again took time to explain the issue and fix in terms someone as myself could understand. They've definitely been added to our list of businesses for future contact!"

"Came when they said they would. Did the job efficiently and thoroughly, explained the probable cause and how to avoid it. Quote was half the amount the other service I contacted quoted as thier base fee ($170 vs $345) and that is what they charged."

"The owner of the company arrived as scheduled and was very professional and a really nice man to deal with. He assured me he would find the location of the access to our septic tank no matter what it may take. He.found it within 15 minutes and it was hidden under rip rap. When he came back to pump it out, he did an excellent job and replaced the rip rap. You wouldn't even know he had been here. I would recommend McAtee highly."

Septic Tanks FAQs, answered by experts

Schedule annual inspections, monitor water pressure, and address minor issues promptly to avoid major repairs.

Septic tank odors can happen because of a few different issues with your septic system, such as a full tank, clogged drains, or blocked venting systems. Not only is a smelly septic tank pretty unpleasant, but it can also pose a potential hazard to yourself and your home. Toxic fumes could be hanging around, or untreated wastewater could be harming the environment.

A septic tank with a 1,500-gallon capacity is good for larger homes with up to 6 or 7 bedrooms. The average home can go with a smaller tank, about 1,000 gallons, which supports a home size of up to 2,500 square feet, or a home with about three bedrooms.

The best bacteria to add to a septic tank is anaerobic bacteria, which doesn't use oxygen to break down solid waste. Because there is less oxygen in a septic tank, anaerobic bacteria can decompose sludge in a sealed environment. On the other hand, aerobic bacteria need oxygen and are prevalent in the leach or drain field of a septic system.

Perc rates vary dramatically, and a good perc rate could be anything from 5 minutes per inch of drainage to 60 minutes per inch. The lower the number, the faster your system will drain and the more effective it will be. A 60-minute-per-inch drain rate is the highest number considered to be good, or even allowable, draining.
