"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."

Septic Tanks FAQs, answered by experts

The best times of year to empty or pump a septic tank are spring and fall. Many professionals recommend spring because the ground has thawed, making the tank easier to access and the waste less likely to be frozen. Pumping before summer also helps avoid conflicts with vacations or outdoor gatherings. Fall is another great option, as contractors may be less busy, and servicing the tank can reduce the risk of overflow from winter and spring precipitation. While summer is also a suitable time, winter is generally not recommended due to frozen ground.

You can put yogurt in your septic tank, but it will not increase the bacteria in your septic tank. In other words, it won't harm your tank, but it won't get rid of a septic smell or boost the performance of your septic system. While yogurt contains helpful bacteria, you would need to buy an extraordinary amount of yogurt to make any difference. Adding yogurt is not a helpful or cost-effective strategy.

Septic systems typically require servicing every 3-5 years, but frequency varies according to household size and tank capacity.

On average, you should call a pro to pump your cesspool once per year. If you have a larger home with a lot of family members, you may need to pump more (up to six times per year). On the flip side, if you’re talking about a cesspool for a home you don’t use much or if you’re the only occupant in a home, you won’t have to pump nearly as much.

A septic alarm can sound different depending on your system, but often, it’s a loud, repetitive beeping noise or a steady, high-pitched noise. It may also be a loud buzzing noise. To confirm the noise is your septic alarm, check your alarm box for a red light. You can also silence your alarm with a red button or switch on the box. Look for something that says “Test” or “Mute.”
