"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 water refills in a well through gravity that draws water from the water table to fill the vertical hole. The pump brings the fresh water through a pressure tank and to the pipes in your house. The well continues to refill indefinitely as long as you don’t use more water than the well is producing.

The best solar-panel mounting system will depend on your property layout, but you’ll typically want to try for south-facing panels to get the most sun. Roof mounting and wall mounting are both popular, but if your well setup is far away from buildings and other structures you can also set up a freestanding aluminum frame to mount your panels.

The price you’ll pay for service from a septic tank company will depend on the specific service you need. Here are some common services, along with average pricing:

  • Anaerobic septic system installation: $3,000–$8,000

  • Aerobic septic system installation: $10,000–$20,000

  • Septic tank pumping: $250–$550

  • Percolation test: $700–$2,000

  • Leach field installation: $2,000–$10,000

These numbers vary based on your septic system size, property layout, and more, so the best way to get an accurate estimate is to contact a septic tank professional for a custom quote.

When considering the price of drilling a well, factor in how much you’ll save in water costs per year. The average family of four uses 100 gallons of water per person per day in the U.S. With a private water well, you can save hundreds each year.

Wells are also environmentally friendly. You don’t need to worry about drinking water treated with chemicals. Talk to at least three well pump contractors in your area. They’ll be able to tell you more about your options, give you different quotes, and discuss the biggest concerns.

Wells typically replenish at a rate of about five gallons per minute, but several variables can influence how quickly they refill. A deep well will take more time to replenish than a shallow one. The replenishment rate can be slowed by issues such as leaks, damage, a faulty well pump, or a clogged well screen. Other factors, such as the surrounding geology, regular precipitation, and proper maintenance, also affect the recovery rate.
