"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

You can check your own septic tank, but take precautions. Locate the access lid, usually buried a few inches underground, and remove it carefully. Look for the sludge and scum levels, and if they’re high, that means pumping may be necessary. Check for odors, slow drains, or pooling water around the drain field, which could indicate issues. Never enter the tank, as toxic gases can be fatal. All of that being said, a professional inspection is safer and more thorough.

The best times of year to empty or pump a septic tank are spring and fall. Many professionals recommend spring because the ground has thawed, making the tank easier to access and the waste less likely to be frozen. Pumping before summer also helps avoid conflicts with vacations or outdoor gatherings. Fall is another great option, as contractors may be less busy, and servicing the tank can reduce the risk of overflow from winter and spring precipitation. While summer is also a suitable time, winter is generally not recommended due to frozen ground.

To determine the right size for your submersible well pump, find your well depth, water demand, and well casing diameter. The pump should match your well's specifications and meet or exceed your drawdown and pressure requirements. 

For precise sizing, make sure to research the different well pump sizes, consult the manufacturer's recommendations, or seek guidance from a professional well pump installer.

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.

With so much available information about the ecological effects of cesspools (and their general unpleasantness), it begs the question: Are cesspools legal? In short, sort of. Large-capacity cesspools that serve more than 20 people are completely illegal countrywide. Existing, smaller cesspools are generally allowed as long as they’re not actively polluting. However, new cesspools are illegal to build in all 50 states and Puerto Rico, and many states offer programs to help homeowners with the costs of updating cesspools to modern septic systems.
