"I was given a very reasonable price for the pumping of my 1500 gallon septic tank, after my last septic guy increased his price by quite a bit. They were very professional and flexible with scheduling, which was fantastic. Saul came out on a Saturday, and even cleared out the foliage over my septic tank lid without charge. I will be using them again in the future for sure."

"DDC was hired to clear and grade a building site. Exceeded my expectations. Was on time and done before schedule. After building was erected the team was back to finish grade, seed and straw, and repair rock lane. Would and have recommended DDC for any earth moving job."

"Excellent response. Pipe disconnect found immediately. Just needed gluing. The technician quickly explained and stated cost would be $89.00. I was SO relieved and happy. This company (unlike last one used which Angie's List rated as #1) included dispatch fee in price since repair was done during 1st visit. No hidden costs. No lies @ discounts."

"Bucky is the absolute best! I called a few other businesses to install my septic tank but he was by far the most professional, prompt, and genuine that I could find out there. As a bonus, he was very reasonable on price also! On a scale of 1 to 5, this man is a 10! Thanks again for the Yeoman's work!"

"Nathan was awesome to work with. I hired him to just certify my septic system on a new home that I bought, instead I had to have my whole septic moved and replaced! He did it in a timely fashion as much as he could with Inspections and rain delays. Good thing I didnt move in the house yet. I will definitely recommend Eagle and Son Septic Services."

"James provided the service on our call. He was very professional and polite. An earlier call went longer than expected and he called to let us know when we could expect him. The quality of his work was excellent. Everything looked great, works great weeks later and he cleaned up afterward. His pricing was fair and I have no complaints given the final product. I can highly recommend Skyes Plumbing if you want prompt and professional service."

Septic Tanks FAQs, answered by experts

The pressure in a well pressure tank should be set 2 to 3 PSI below the pump's cut-on pressure. The cut-on pressure is the lower number in the pressure setting (e.g., the '30' in 30/50 PSI) and is the point at which the pump starts. The cut-out pressure is the higher number, where the pump stops.

For example:

  • If your pressure switch is set to 30/50 PSI, the tank pressure should be 27-28 PSI.

  • If your pressure switch is set to 40/60 PSI, the tank pressure should be 38 PSI.

Common pressure settings for household applications include 20/40, 30/50, and 40/60 PSI. The difference between the cut-on and cut-out pressure is typically 20 PSI.

Because well water is not artificially filtered or pre-treated, it may contain contaminants. As a result, it’s possible for well water to damage pipes based on what is in the water. Well water can be corrosive, slowly rusting and dissolving pipes, fixtures, and fittings. The corrosion can affect the taste and quality of the drinking water that comes out of the taps in your home. 

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.

Your septic tank naturally contains the good bacteria it needs, so you typically don't have to add more as the system produces them on its own. However, if you wish to replenish the bacteria, you can use natural methods. For example, you can add three rotten tomatoes to your garbage disposal or flush 1/4 ounce of active yeast down the toilet every three months. While store-bought septic enzymes and chemicals are available, many additives are unnecessary and may even harm your system. The most effective way to maintain a healthy bacterial balance is to avoid using chemical drain cleaners, which can kill the beneficial bacteria in your tank.

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.
