"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

You can add three rotten tomatoes or 1/4 ounce of yeast to your septic tank to speed up the decomposition of sludge. You can add the tomatoes by way of your garbage disposal and the yeast by way of your toilet. You can do either of these additives once every three months as needed.

The dimensions of a 500-gallon concrete septic tank can vary from manufacturer to manufacturer, but the tank is large enough to handle the wastewater of a small home with up to one bedroom. Keep in mind that some states have a minimum septic tank size, and this often starts at 750 gallons. A 500-gallon septic tank may be too small to meet local regulations.

A septic tank always has some amount of liquid in it—which should usually be 8 to 12 inches from the top of the tank. If the liquid level is higher than that or is overflowing the drainage pipe that leads out to the leach field, the tank may be too full and in need of pumping.

The best solar-panel mounting system will depend on your property layout, but you’ll typically want to try for south-facing panels to get the most sun. Roof mounting and wall mounting are both popular, but if your well setup is far away from buildings and other structures you can also set up a freestanding aluminum frame to mount your panels.

Yes. A metal detector is one of the quickest and easiest ways to find your septic tank. However, metal detectors can be too expensive (costing upward of $300 in some cases), and not everyone has a metal detector just lying around. If that’s the case for you, you can also take a long metal rod and poke it into the ground at regular intervals until you hit something—likely your septic tank lid.
