"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

The bacteria already present in your septic system should be enough to break down solids in a properly maintained septic tank. However, if you’re in a DIY mood, you can try adding (well-mashed) rotten tomatoes to help the good bacteria fulfill their duty. Just make sure you give them a couple hours to work after flushing them down.

The cost of sump pump installation varies depending on factors like the type of sump pump, labor rates, and the complexity of the installation. On average, you can expect to pay around $1,200 for a standard sump pump install. However, the cost may be higher if additional features like a backup system or extensive drainage work are required.

The best bacteria to add to a septic tank is anaerobic bacteria, which doesn't use oxygen to break down solid waste. Because there is less oxygen in a septic tank, anaerobic bacteria can decompose sludge in a sealed environment. On the other hand, aerobic bacteria need oxygen and are prevalent in the leach or drain field of a septic system.

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.

Frozen well pipes make themselves known quickly, as your faucets slow down to a trickle or shut down completely. If you notice a serious reduction in flow in the winter from toilets, showers, kitchen faucets, and other plumbing fixtures, a frozen pipe or two is to blame. Another tell-tale sign is frost or ice on exposed pipes outside.
