"Brent and his guys were the best! I am exceedingly happy I selected them to replace my septic tank. This was a major project for me that had the potential to delay the sale of our home. Brent & company came in with the knowledge, equipment and skills that were required to complete the job professionally and efficiently. There was a couple of unforeseen issues but Brent was able to resolve them without batting an eye! He also absorbed the added costs on his own even though I offered to split the difference. I had contacted a number of other firms top do this job and Brent came back with the most professional and detailed quote. He then came out promptly for a site survey- something most of the others did not deem necessary. I have worked around construction contractors for decades and pesonally feel that Fox Excavating LLC is one of the best I have seen!"

"Andrew did a great job fixed my upstairs toilet, had other plumbers try to figure out why the toilet wouldn't drain, Andrew used a camera in the main drain and found the problem. Awesome job, we are all set with the toilet and he checked the whole house for any other issues. We will use Andrew in the future, we highly recommend his services."

"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

Leach lines are commonly made of PVC pipe, and they’re placed into trenches filled with gravel and sand, which help treat the wastewater. The PVC pipes are perforated, or drilled with small holes, so the wastewater can drain out of the pipes and into the surrounding material, which eventually leads to the aquifer.

While homeowners connected to a municipal sewer line still have to keep up with plumbing maintenance, the downside to a septic system is that all the maintenance falls on the homeowners. Not calling in a pro to pump the tank every few years or accidentally flushing or draining the wrong types of materials can quickly cause clogs, which can back up into drains around the home.

The main difference between a mound septic system and a conventional one is that the drain field in a mound system is built up into a mound composed of sand and gravel to increase the filtration time the wastewater sees before it is returned to the aquifer. There’s also a significant cost difference, with mound systems typically costing far more than standard septic systems.

Most septic tanks need to be emptied every 3 to 5 years, but it’s a good idea to monitor the fill levels of your septic tank all the time. You can do this by installing a pressure level sensor to detect the internal tank pressure, or by having a septic tank company perform an annual inspection to let you know when you’ll need to pump the tank.

When a septic tank is full, it needs to be professionally pumped. The average cost of a one-time septic tank pump is about $400, or $0.30 per gallon. If your septic tank is full, you may notice that you have issues flushing your toilet, pipes are draining very slowly, or you have a sewage smell lingering in your home or yard.
