"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

Most shallow residential wells are somewhere between 25 and 50 feet deep. They are among the simplest well systems. Deeper wells usually involve drilling to a much greater depth. Water wells for household use are typically 100 to 500 feet deep, depending on local groundwater conditions. Some may be up to 1,000 feet deep or more. 

You can put yogurt in your septic tank, but it will not increase the bacteria in your septic tank. In other words, it won't harm your tank, but it won't get rid of a septic smell or boost the performance of your septic system. While yogurt contains helpful bacteria, you would need to buy an extraordinary amount of yogurt to make any difference. Adding yogurt is not a helpful or cost-effective strategy.

The average three to four-bedroom home typically uses a well pump rated for 8 to 12 gallons per minute (GPM). To find the most accurate size for your specific needs, a common rule of thumb is to count the number of water fixtures and appliances in your home and aim for that number in GPM. This calculation allows for about one gallon of water per minute per fixture. Because estimating the correct size can be challenging, it's best to have a professional technician make the final determination. A professional can ensure your pump provides sufficient water for your home, especially during peak usage hours.

Septic tank locations are sometimes public record, although it depends on local laws and the property age. Older properties may not have the septic tank information on public record. To check, you can talk to local permitting agencies, such as your local health department, the local environmental department, or the county clerk.

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.
