"We recently had this company replace our original 1000 gallon septic tank with a 1500 gallon upgrade, along with an additional drain field line and they did a great job. If you want people who are skilled, hardworking and honest to handle your project, then I recommend that you give NC Septic & Pump your consideration. Their communication is excellent and they are very easy and pleasant to work with."

"He over charged me. I paid 1500.00 for my septic tank to be cleaned out and rejuvenated it, as he called it. He quoted over the phone 400.00, so I expected to pay 600.00. When he got here he started to tell me about an easier way to find my septic tank for next time. He was going to add risers for me. He said the price of that was 2800.00 I was like I ca not afford that, so maybe another time. He told me he would charge me 1500,00 to do the whole job. He said he would give me a first responders discount, I told him I work in the Emergency Department at a hospital, plus I was still in my uniform when I met him, I had just gotten off of work. He said that he counts that as a first responder. Then, he said he would give me a first time customers discount and the total went from 2800.00 to 1500.00 but I had a water line directly over the tank and he could not do the risers, but he still charged me 1500.00. I felt like I was ripped off! It had to be cleaned out and I just wanted to get it done so that I could shower and go to sleep. He came out on a Monday morning a little after 9am. It was not a holiday or weekend. He did not do any extra work that would have cost 1500.00. I was confused and just paid him. Even though I felt like he was ripping me off. He did clean out all the materials inside of my septic tank. He was friendly and explained how the septic tank worked. I still feel like I triple paid for a job."

Septic Tanks FAQs, answered by experts

Bladder and diaphragm well pressure tanks are usually pre-charged at the factory. Even so, it’s important to check the air pressure in the tank using a tire pressure gauge on the relief valve. The instruction manual usually calls for 28 psi. Use a hand pump to add more air or release some air from the tank to reach the desired number. Check the pressure periodically to see if you need to add more air to the tank.

Your septic tank may be full or clogged if you notice household drains that are backed up, draining slowly, or gurgling; greener, lusher grass around the septic system; pooling water in your yard; or smelling sewage odors outdoors. You can contact a local septic tank pro to inspect your septic system and pump your tank.

Yes, a bigger well pump can increase water pressure—up to a point. If you currently have a well pump of 8 GPM, you might notice a pressure boost when you go up to 10 GPM. However, overshooting significantly (going up to 15 GPM for an 8 GPM home) can strain your well system and result in things like burst pipes that can decrease your water pressure and make for costly repairs.

Drain fields often include three to five trenches that are 18 to 24 inches deep. The pipes connecting the drain field to the septic tank will be placed between 12 and 18 inches deep, and the field as a whole will be about 100 feet long.

Most septic tanks need to be emptied every 3 to 5 years, but it’s a good idea to monitor the fill levels of your septic tank all the time. You can do this by installing a pressure level sensor to detect the internal tank pressure, or by having a septic tank company perform an annual inspection to let you know when you’ll need to pump the tank.
