"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

Watch for slow drainage, pooling water in the yard, or unpleasant odors inside or outside. Addressing these issues timely avoids significant disruptions or costs.

The purpose of a septic tank is to allow solid wastes to separate out of the wastewater using time, gravity, and other natural biological processes. If your septic tank is too small, it might be overwhelmed by solid waste and unable to accomplish this task—and if it’s far too large, there won’t be enough liquid in the tank to nurture the necessary bacteria to aid in the breakdown process.

The bacteria already present in your septic system should be enough to break down solids in a properly maintained septic tank. However, if you’re in a DIY mood, you can try adding (well-mashed) rotten tomatoes to help the good bacteria fulfill their duty. Just make sure you give them a couple hours to work after flushing them down.

A septic system can fail for various reasons, and most commonly, excessive water use or sudden surges in wastewater can overwhelm the system's capacity. Neglecting regular maintenance, like tank pumping and inspections, can also lead to clogs, leaks, and eventual breakdowns. Other issues that lead to failure include age-related wear and tear, root infiltration, improper disposal of non-biodegradable materials or chemicals into the system, unsuitable soil conditions, physical damage, and even environmental factors like flooding or soil erosion.

To keep your septic tank healthy, be careful of what you flush and be conservative with water usage, as even flushing too much water down the drain can throw off the septic system’s delicate balance. Never flush anything but human waste and toilet paper down your toilet, and be sure to have the tank inspected and pumped every two to five years, depending on the size of your household and your water usage.
