"Noticed we were starting to have issues with our septic tank. Gave Thigpen a call and set up an appointment for the next day. They were here on time and completed the job quickly. No trying to talk me into any other services I didn't need, no bs, just straight up honest work. Will definitely hire again when the time comes."

"Somehow rain water was flooding into my septic tank causing it to backup into the house - yuck!  Jim came out after 9:30 p.m. on a Sunday to rod the sewer out to the septic tank and scheduled a day to come out the following week to inspect and replace the main sewer line if needed (they were working a major construction job and that was the earliest that he was available).
The following Saturday when the forecast called for heavy rains late afternoon - Jim called me and came out with another plumber and apprentice to dig up and replace the main sewer line in advance of  the heavy rainfall.  
Needless to say, it worked and there was no flooding at all during the rainstorm - we even flushed toilets and my daughter took a shower, but no backup and all the drains worked flawlessly!"

"Great experience working with Jacob, listening to the issue, quickly diagnosing and confirming what work needed to be performed to resolve both the clogged drain and leaky piping underneath the sink and explaining the process all along. He promptly cleared the line using the hydro-jet and replaced the galvanized piping with PVC including the install of a new cleanout valve. Afterwards, he cleaned up the work area not leaving a mess which is appreciated. The price was reasonable considering the circumstances and he was very efficient. I will not hesitate to call them again if I have another plumbing issue and would recommend them for plumbing 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

It only takes a few days for a septic tank to fill with water after a pro has pumped it. This is completely normal, and the water is a vital part of your septic system’s wastewater treatment process. The water that fills your tank days after pumping is not the same as the tank being filled with waste. You shouldn’t have to pump your septic system more than once every three to five years unless you have a tank that’s too small for your home’s water output or there’s a problem with your leach field. 

There are a variety of different types of septic systems that can work in your home—such as conventional anaerobic systems, chamber systems, drip distribution systems and mound septic systems. All of them work using natural processes to break down solid waste and effectively treat wastewater without needing to be connected to a city sewer system. Which type of septic system you need will depend on characteristics of your property like how high the bedrock is or groundwater table is. Different types of systems come at different costs to install.

Drilled wells have a pipe sticking up that’s covered in a plastic or metal casing. On the other hand, a dug well will look like a big hole in the ground and is more similar to what you’d see in a fantasy or Western movie. If you want to be sure, contact the city for documentation on your property’s construction and excavation history. 

There are many reasons you may want to extend the depth of an existing well or drill a new, deeper well on your property. A deeper well can tap cleaner water sources—shallow water may contain more contaminants. With a deeper well, you’ll also have an easier time reaching the water table depth (the level at which underground water is found) and can get past tricky soil conditions. 

Plus, if your local building code requires a minimum well depth for safety and environmental standards, you’ll meet the code by digging a deeper well in the first place.

Septic distribution boxes, also called D-boxes, tend to last over 30 years if taken care of extremely well. In most cases, however, they tend to last anywhere from 15 years to 40 years. Regular cleaning and maintenance, as well as living in an area that doesn’t flood the tank or the system regularly, will all have an impact on the lifespan of the box.
