"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

Your septic tank naturally contains the good bacteria it needs, so you typically don't have to add more as the system produces them on its own. However, if you wish to replenish the bacteria, you can use natural methods. For example, you can add three rotten tomatoes to your garbage disposal or flush 1/4 ounce of active yeast down the toilet every three months. While store-bought septic enzymes and chemicals are available, many additives are unnecessary and may even harm your system. The most effective way to maintain a healthy bacterial balance is to avoid using chemical drain cleaners, which can kill the beneficial bacteria in your tank.

Several things can ruin a septic tank over time, including dumping harsh chemicals (like bleach and ammonia), pesticides, and paint thinners down your drain because they can kill the bacteria in your septic tank. You should also make sure to only flush waste and toilet paper in your toilet—otherwise, you could clog your system.

A mound septic system, when properly maintained, can last between 20 and 25 years on average—though some last longer or malfunction sooner than that. The most important part of maintenance is getting an annual inspection of the vital parts of the system to ensure they’re in proper working order and not too backed up with sewage.

Getting well water tested costs $100 to $350 if done by a pro. You can also buy DIY test kits for $20 to $100, but professional tests are more reliable. You can get a comprehensive well inspection, which includes advanced water testing, for $700 to $750, which you should do yearly anyway.

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.
