"Very impressed with this company. Emmanuel came to our home, he was professional, knowledgeable, friendly, cared about quality work and wasn’t leaving until he got our problem to a good spot. He cleaned the septic, and dug up the filter cover which was seized up. He had a new one on his truck and had to bust up the old one to get it out. He found no filter, but found a clog in the line going away from the septic tank. He sucked that clog out and knew there was probably another one. He set us up for that repair to be done soon as well. We are having a cover put over this area too. That will be done soon too. He explained how the system works , then told me what they would need to do to correct our problem, which was to run a camera and probably clear another clog out to prevent our system from certain backup problems. I am just so impressed with the service Emmanuel did and how sweet he was. It’s nice to have an honest company who cares about the service that they do."

"Jettie Excavation did a great job and was accommodating. Cody, the owner, was communicative, realistic about timelines and logistics, and accommodating of our evolving timeline on a new residential build site. Although a new septic system is pretty regulated in Vermont, I gleaned that Cody is also creative and proactive at problem-solving. Overall, he was great to work with on this project."

"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

Having a well means that a household’s water supply, including water that comes through faucets, showerheads, and appliances, is supplied through a private source rather than from a city. The well pulls fresh water from an underground water supply, such as an aquifer, and the well pump pushes the water from the well to your household.

Yes, a septic tank riser can replace a concrete septic tank lid. Risers are designed to replace various types of septic tank covers, including concrete, metal, and fiberglass, to provide easier access for pumping and repairs. While a plastic riser makes future access more convenient, the initial replacement can be difficult because concrete lids are very heavy, so it is a job best left to professionals. Once installed, you will need to be cautious around the riser during yard work, such as mowing, to avoid causing damage.

If you notice that your well pump runs continuously, it’s important to take action quickly to avoid further damage. A few common issues may be to blame for a continuously running well pump, such as mechanical damage, a faulty pressure control switch, low water level, prime loss, and leaking pipes and fixtures.

When your septic system is failing, you’ll probably smell it. Common signs of a septic system failure include sewage odors in the home or around the yard, flooding in the yard above the septic tank or in the leach field, and wastewater or even raw sewage backing up into your home’s drains.

Your garbage disposal will only affect the health of your septic tank if you’re using it too frequently, or filling it with organic waste that doesn’t fully break down. If the tank fills up with too many solids, the bacteria won’t have enough time to consume it before more is added, which can lead to an overflow in the drain field. Your tank will need to be pumped more frequently with excessive or improper garbage disposal use.
