"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

Mound systems can fail if foreign objects are flushed into the septic tank, the septic tank is backed up with solid waste (sludge), if wastewater floods or seeps from the mound, or if any part of the system is clogged. To prevent this, only flush toilet paper and your normal “business” down toilets, and get a septic inspection at least yearly.

While you can drain water softener backwash into a septic tank, doing so may cause several problems. One problem is that increased sodium chloride levels from water softener backwash can kill septic tank bacteria, decreasing the effectiveness of this wastewater treatment system. Another issue is that large calcium deposits can eventually stop up the drain field and lead to poor drainage. 

How do you set your well’s pressure tank? All you need to do is first drain the tank of water and find the pressure switch. Remove the switch cover and adjust the switch with a wrench—clockwise to increase water pressure, and counter-clockwise to reduce it. Each complete turn of the nut on the switch should equal 2.5 psi. Once this is done, replace the switch cover. All that’s left is to adjust the pressure of the tank itself using an air compressor and a tire gauge to support the new setting.

A septic alarm can sound different depending on your system, but often, it’s a loud, repetitive beeping noise or a steady, high-pitched noise. It may also be a loud buzzing noise. To confirm the noise is your septic alarm, check your alarm box for a red light. You can also silence your alarm with a red button or switch on the box. Look for something that says “Test” or “Mute.”

With proper maintenance, most types of septic systems—including mound, evapotranspiration, and constructed wetland systems—can last up to 40 years. To keep your system running as long as possible, follow basic septic tank upkeep guidelines, like pumping your septic tank every three to five years and only flushing human waste and toilet paper.
