"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

Beyond the type of well pump, there are a few other factors to consider when selecting a well pump. Keep in mind the depth of your well, your average water usage, and the PSI of your water-consuming appliances to determine the appropriate motor horsepower and size of your well pump.

To prevent septic tank problems, save on repair costs, and keep your home running smoothly, it's essential to perform regular maintenance. Have your septic system inspected by a professional every one to three years, or annually if possible, to spot potential issues before they develop. You should also have your tank pumped every three to five years, or more frequently if recommended by a professional based on your household's usage. Additionally, be mindful of what goes into your system. Avoid flushing items like paper towels, wet wipes, and feminine hygiene products. Do not dispose of other inappropriate substances, and try to avoid excessive water usage at a single time.

Several things can ruin a septic tank over time, including dumping harsh chemicals (like bleach and ammonia), pesticides, and paint thinners down your drain because they can kill the bacteria in your septic tank. You should also make sure to only flush waste and toilet paper in your toilet—otherwise, you could clog your system.

The size of your septic tank plays a role in determining the proper size of the drain or leach field. As a general rule, you should have 1 square foot of drain field size per gallon of septic tank capacity. However, you could install a leach field that’s as much as 2.5 square feet per gallon of septic tank capacity. Most professionals determine the right septic tank size and drain field size by the number of bedrooms in the house. A three-bedroom house needs a minimum 1,000-gallon septic tank, for example.

It only takes a few days for a septic tank to fill with water after a pro has pumped it. This is completely normal, and the water is a vital part of your septic system’s wastewater treatment process. The water that fills your tank days after pumping is not the same as the tank being filled with waste. You shouldn’t have to pump your septic system more than once every three to five years unless you have a tank that’s too small for your home’s water output or there’s a problem with your leach field.
