"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

Your drain field or leach field should be 1 to 3 feet under the ground. It will be a little shallower than the septic tank, although it can be the same depth or slightly deeper. The proper depth of the septic tank is up to 4 feet. It’s possible that your local regulatory agency requires a certain depth for your drain field.

How to size a well pressure tank is determined by three factors: flow rate, or how many gallons per minute your well pump produces; minimum runtime; and pressure switch setting. Most pressure tanks have a pressure switch operating at 20/40, 30/50, and 40/60—the first number is the pressure needed for the pump to turn on, and the second number is the pressure needed for the pump to switch off. Most homeowners relying on well water require a water pressure tank ranging from 20 to 80 gallons. 

Yes! Toilet paper can be flushed if you use a septic tank. While unique toilet papers designed to be used with septic tanks are available, many people have no problem flushing regular toilet paper with a septic tank, so long as you don’t flush too much toilet paper all at once. Do not flush any type of baby wipes or bathroom wipes, even if they say “flushable.”

Certain foods are easier on your septic tank than others. Septic-safe foods include yogurt, fruit, cooked veggies, and bread because these items all break down relatively easily and can pass through your system safely. Rotten tomatoes, specifically, are actually good for your septic tank because they can increase the amount of good bacteria in the system. 

You should never park or drive on top of a septic field. Vehicles can weigh upwards of two tons, and this weight can put a lot of pressure on the leach lines in the drain field. Too much pressure on your leach lines may cause them to warp, crack, or completely burst. This is an expensive and very avoidable problem.
