"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 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.

Septic tanks naturally have bacteria that break down some of the solid waste in the septic tank. However, sludge buildup is just part of owning a septic system. While liquid wastewater can be filtered and treated through the system, a septic tank company has to pump the septic tank out at least every few years.

Pump the tank every 3-5 years, avoid flushing non-degradable items, and address leaks promptly to extend system life.

Digging a well can cost between $20 and $25,000, depending on your needs. If you’re looking to dig a well yourself, all you need is a shovel. If you’re looking to have a well drilled by a professional, you can expect to pay around $15 to $30 per foot. The total cost of drilling a well will average to $5,500.

You can check your own septic tank, but take precautions. Locate the access lid, usually buried a few inches underground, and remove it carefully. Look for the sludge and scum levels, and if they’re high, that means pumping may be necessary. Check for odors, slow drains, or pooling water around the drain field, which could indicate issues. Never enter the tank, as toxic gases can be fatal. All of that being said, a professional inspection is safer and more thorough.
