"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

Septic tank odors can happen because of a few different issues with your septic system, such as a full tank, clogged drains, or blocked venting systems. Not only is a smelly septic tank pretty unpleasant, but it can also pose a potential hazard to yourself and your home. Toxic fumes could be hanging around, or untreated wastewater could be harming the environment.

Yes, it is possible to drill a well by hand, but it calls for a good deal of physical labor. Drilling a well by hand is best suited for softer soil, and it may not be possible through rockier terrain. For wider and deeper holes, companies with professional equipment make the job much easier.

Needing to pump the tank as soon as it “looks” full is a common myth about septic systems, as wastewater will eventually drain into the leach field. Instead, it’s better to determine how many solids have accumulated. A septic maintenance technician near you can test this to find out whether pumping is necessary.

Ideally, you should conduct a mechanical inspection and a bacterial or well water inspection yearly. While you might be able to push it off to every other year, it’s best to have peace of mind, especially when it comes to something that you use so frequently. 

If you experience repeated gastrointestinal illness in the household, it's important to test the well water more regularly for quality and cleanliness to check for bacteria.

Unlike an urban sewer system that runs wastewater into a central drainage system, septic tanks are a house-by-house system. They are the ultimate destination for all your house’s wastewater—from bathtubs, showers, sinks, toilets, and washing machines. Wastewater flows into a tank buried in the ground outside your home, and then water runs from the tank to a drainage field using sloped pipes.
