"I contacted Andy from Area Septic Installation Inc. because I was selling my house and the septic system did not pass the inspection. I normally contact 3 providers to get the best price. Andy was the only one to call me back and to come out to the house. Andy was very friendly, and provided me with great information and no hassle/pressure bid. Because I was selling the house there was a tight deadline on getting the work done. The time of year that I needed the work done is extremely busy and the weather did not cooperate. Andy also took time to explain to me some of the deceptive practices in this line of work and cautioned me not to become victimized. I thought that in and of itself was remarkable that he gave me this information so I would not become victimized. Andy showed up on the day he said he would be there, and got to work immediately. Andy knew that I was on a tight deadline to close and he worked long and extra hours to get the job done. His price was very reasonable for the work that needed to be done. Andy did everything to make this as easy as possible, and did a great job. When the work was completed Andy wanted me to come check the work to make sure it was up to my satisfaction before he left. Andy had the yard looking great back to its natural look. If you are in need of septic work I would strongly suggest calling Area Septic Installation Inc. for the work. Hard workers, Honest contractor, and fair pricing what more could you want. Jim Z."

"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

Your septic tank naturally contains the good bacteria it needs, so you typically don't have to add more as the system produces them on its own. However, if you wish to replenish the bacteria, you can use natural methods. For example, you can add three rotten tomatoes to your garbage disposal or flush 1/4 ounce of active yeast down the toilet every three months. While store-bought septic enzymes and chemicals are available, many additives are unnecessary and may even harm your system. The most effective way to maintain a healthy bacterial balance is to avoid using chemical drain cleaners, which can kill the beneficial bacteria in your tank.

On average, you should call a pro to pump your cesspool once per year. If you have a larger home with a lot of family members, you may need to pump more (up to six times per year). On the flip side, if you’re talking about a cesspool for a home you don’t use much or if you’re the only occupant in a home, you won’t have to pump nearly as much.

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.

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 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.
