"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

A gurgling toilet usually doesn’t mean that your septic tank is full. If waste can’t drain into a full septic tank, you’ll see water and sewage backing up into your fixtures, but the air that causes gurgling is a result of poor venting. You are more likely to have a clog in your vent stack or a damaged air admittance valve.

It only takes a few days for a septic tank to fill with water after a pro has pumped it. This is completely normal, and the water is a vital part of your septic system’s wastewater treatment process. The water that fills your tank days after pumping is not the same as the tank being filled with waste. You shouldn’t have to pump your septic system more than once every three to five years unless you have a tank that’s too small for your home’s water output or there’s a problem with your leach field. 

Septic tanks come in multiple shapes, sizes, and materials. However, they’re often round or rectangular in shape and made from concrete, fiberglass, or plastic. There’s a range of septic tank sizes, with the average model measuring 30 to 40 square feet and holding 1,000 to 1,500 gallons of waste.

Although cesspits may be necessary depending on your main sewage system access or nearby soil quality, they carry a few drawbacks. Cesspools require regular emptying and have relatively high maintenance and pumping costs. Certain areas also disallow the use of cesspools and may require you to cover the cost of existing cesspools to be converted into septic tanks.

Conventional anaerobic septic systems are the most cost-effective and least expensive type, with installation costs typically ranging from $3,000 to $8,000. For comparison, sand filter systems cost between $7,000 and $18,000, while mound systems are the most expensive at $10,000 to $20,000. Several factors influence the final price. The tank material is a key consideration; plastic tanks are the most budget-friendly option, starting around $2,900, but concrete and fiberglass tanks offer greater durability and longer life spans at a higher cost. The size of the tank also affects the price. For example, a 1,000-gallon tank costs between $900 and $1,500, whereas a larger 1,500-gallon tank costs $1,500 to $2,500.
