"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

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.

The pressure in a well pressure tank should be set 2 to 3 PSI below the pump's cut-on pressure. The cut-on pressure is the lower number in the pressure setting (e.g., the '30' in 30/50 PSI) and is the point at which the pump starts. The cut-out pressure is the higher number, where the pump stops.

For example:

  • If your pressure switch is set to 30/50 PSI, the tank pressure should be 27-28 PSI.

  • If your pressure switch is set to 40/60 PSI, the tank pressure should be 38 PSI.

Common pressure settings for household applications include 20/40, 30/50, and 40/60 PSI. The difference between the cut-on and cut-out pressure is typically 20 PSI.

Most professionals recommend that a deep well pump shouldn’t run more than 10 hours consecutively before cycling off. Overworking the well pump beyond the recommended amount can prematurely wear out your pump and burn out the motor, which means replacing it more often than you otherwise should need to. Your well pump should also come with the manufacturer’s use and maintenance recommendations that are specific to the model.

A septic tank with a 1,500-gallon capacity is good for larger homes with up to 6 or 7 bedrooms. The average home can go with a smaller tank, about 1,000 gallons, which supports a home size of up to 2,500 square feet, or a home with about three bedrooms.

Septic tank odors can happen because of a few different issues with your septic system, such as a full tank, clogged drains, or blocked venting systems. Not only is a smelly septic tank pretty unpleasant, but it can also pose a potential hazard to yourself and your home. Toxic fumes could be hanging around, or untreated wastewater could be harming the environment.
