"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

The size of your septic tank plays a role in determining the proper size of the drain or leach field. As a general rule, you should have 1 square foot of drain field size per gallon of septic tank capacity. However, you could install a leach field that’s as much as 2.5 square feet per gallon of septic tank capacity. Most professionals determine the right septic tank size and drain field size by the number of bedrooms in the house. A three-bedroom house needs a minimum 1,000-gallon septic tank, for example.

DIY is not recommended due to safety and technical requirements. Hire professionals for accurate diagnosis and repair.

A household of four can easily fill a 1,000-gallon septic tank within a week. It may be 10 to 14 days for smaller households. But the reason why you don't need weekly pumping is because the tank's contents eventually reach the overflow pipe. They flow down this pipe to the absorption area whenever water is used in your home. The tank keeps working at this full level until it's pumped again.

According to the Environmental Protection Agency (EPA), septic tanks must be located a decent distance from places subject to flooding or surface ponding. Additionally, septic tanks should be installed on level ground so that the waste can properly settle in the tank. Most tanks are located 10 to 20 feet away from the home. More specific requirements vary by location, so call a local septic pro or your local health department for more information.

Depending on local conditions, a deep well may be a better choice than a shallow well. Deeper well depth accesses groundwater that has been naturally filtered through many layers of soil and rock. This reduces surface contaminants and may offer cleaner water, but deep wells cost more money to build and maintain. The water may be harder and have higher radioactivity, too.
