"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 questions, answered by experts

The depth of your septic tank has nothing to do with its size. In fact, some septic tanks can even be installed above-ground! Like other sizes, a 1,000-gallon septic tank could be buried as shallow as 4 inches below the ground or as deep as 4 feet. It all depends on your specific property.

With regular testing, treatment, and maintenance, water from a community well should be safe to drink. Unfortunately, the EPA does not regulate private wells, and contamination can happen. 

If you have doubts about the quality and safety of your drinking water, you have options for testing. You can pick up kits from your local home supply store or harvest samples and send them to a local testing facility. To get the most complete water quality testing and system diagnosis, seek a local well professional. They know what to test for and can recommend and implement a longer-lasting solution.

Septic distribution boxes, also called D-boxes, tend to last over 30 years if taken care of extremely well. In most cases, however, they tend to last anywhere from 15 years to 40 years. Regular cleaning and maintenance, as well as living in an area that doesn’t flood the tank or the system regularly, will all have an impact on the lifespan of the box.

While a traditional septic tank requires a leach field for wastewater disposal, it is possible to have a septic system without one. Some alternative systems, which are often used when there isn't enough space for a full-size leach field, include mound systems or sand filtration systems. In a conventional setup, the leach field is essential because it's where the wastewater goes after leaving the tank.

Saving money on property taxes and having direct control over your waste system are both pros when buying a house with a septic tank. However, it’s easier on the house and the yard if a home can be hooked up to a municipal system, which is why septic tanks are best for homes where that isn’t an option. Expensive repairs, potential odor issues, and regular maintenance are all cons of septic systems.
