"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

While a traditional septic tank requires a leach field for wastewater disposal, it is possible to have a septic system without one. Some alternative systems, which are often used when there isn't enough space for a full-size leach field, include mound systems or sand filtration systems. In a conventional setup, the leach field is essential because it's where the wastewater goes after leaving the tank.

If you aren’t sure if you have a septic tank or a cesspit, you can check your property records or inspect your drainage system. A septic tank has an outlet pipe that allows liquid to drain into a soakaway or drain field, while a cesspit is a sealed tank that requires frequent emptying. If you notice a manhole cover and no nearby drainage field, it’s likely a cesspit. Signs like slow drainage or a frequent need for pumping can also provide clues. A professional inspection is the easiest way to confirm if your home runs on a septic tank or cesspit.

There should be a red button or an on/off switch on or in your box. Press the button or flip the switch, then turn it back on by doing the same action again. If this doesn’t work, reset the breakers inside the box by flipping them off and back on again. After this, your alarm should stay off if there’s nothing wrong with your system. However, if the alarm is still sounding and there’s still a red light on, it’s time to call a pro for a diagnosis.

If your leach field becomes clogged or saturated, it can cause several problems with your home's septic system. The clog can cause sewage to back up into your home, leading to unpleasant odors and mess. A backed-up septic system can be a health hazard, particularly if the sewage starts to leach into the ground surrounding the leach field.

There are several ways to fix a saturated drain field, including cleaning out your septic tank, adding enzymes and additives to your drain system, and installing a larger septic system.

Choosing a reliable septic tank company starts by finding an experienced company in your area with positive customer reviews online. You can also use the following tips to help ensure you have a positive experience:

  • Choose a company that is licensed and fully insured

  • Ask the company for customer references

  • Ask if the company provides any guarantee for the repair

  • Determine the provider’s level of experience
