"Im glad i called Smart Septic Solutions because they made the whole process so simple. They answered when I called, were quick to come out to access, and started work on time like they said. They were also able to get to me sooner than all the other companies i called which was a life saver. In all, im glad I was able to find a company that cares for the customers and one the does what they say they will do, when they say they'll do it."

"I specified that it was a tankless water heater, yet not surprisingly I was referred to a plumber who didn't know anything about tankless heaters, resulting in a waste of a couple of days. The second person did know about them, and so far the repair is working (fingers crossed). I wish CHW would pay attention to the details in my claim."

"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

Your drain field or leach field should be 1 to 3 feet under the ground. It will be a little shallower than the septic tank, although it can be the same depth or slightly deeper. The proper depth of the septic tank is up to 4 feet. It’s possible that your local regulatory agency requires a certain depth for your drain field.

For the most part, choosing between 30/50 psi and 40/60 psi is based on your water-pressure preference. However, it can also depend a little bit on your house—if you have older plumbing, a lower water pressure can be easier on the pipes (and a bit more gentle on your well pump). 

The lower 30/50 pressure is usually enough for a single-story home, but you may want 40/60 if you have multiple stories, as the extra pressure helps water flow smoothly up to the second floor.

Yes, a septic tank can get full. If this happens, you might run into issues flushing your toilets or draining your sinks. You may also notice your pipes making gurgling noises or the smell of sewage floating around your house. Other signs of a backed-up septic tank include water pooling or fresh, healthy grass growing above your drain field.

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.

To keep roots from growing into a septic tank. However, there are other steps you can take if existing tree roots are getting close to your septic tank. For one, you can install root barriers, which physically block roots from reaching your septic tank. You can also use chemical solutions in your yard or plumbing system to deter root growth.
