"Within a few hours of submitting my search in Angie's List for a company to empty my septic tank, R&E Chief Septic called to schedule the appointment and provide me with the cost. I was surprised at the quick response and immediately set up an appointment. They were on time and quickly went to work. I will definitely use them from now on!"

"We were in the process of selling our home and the septic inspection revlealed that our drainage field had failed. Legacy septic was very responsive to our closing/reloaction dates and had the drainage field replaced within 7 days of calling. Highly recommend."

"Very professional and courteous.  Cleaned up after their work.  It was the best experience I have ever had with a plumber.  They are locally owned and very responsive - unlike some of the very large companies.  The pricing was reasonable and they worked with me on the options of which replacement tank to use.

"Definitive Plumbing did a great job Installing a tankless electric water heater in my house and it works beautifully! They were extremely responsive and came back to make an adjustment to ensure the water temperature and flow were maximized. They also removed the existing water heater, and although we had a miscommunication about how that would happen, they came back and did some additional work to rectify the issue—which is really the type of customer service you want from a vendor. Keon and DJ are very honorable and they want to make sure the customer is satisfied."

"As a landlord I have had my fair share of plumbing issues.  I am particularly pleased with the service I receive from John owner of Knock You Plumb Out Plumbing.  John has replaced sewer lines for me along with other plumbing problems.  I have even referred John to friends, something I normally am hesitant to do because I don?t want to be involved if there are problems with the quality of the work.  But with Knock You Plumb Out Plumbing I am confident of quality work and service.  I highly recommend John.

"We were having problems with our septic. 1 st we had the tank pumped. Continued to have problems with backing up. Zack and his helper came out and snaked the clean out pipe. Worked for a couple weeks backed up again. Bryan and his helper came out and snaked the pipe again and ran the camera in the pipe which showed tree roots clogging up the pipe. He then ran a root cutting tool in the pipe. As Bryan was doing all of this he explained everything he was doing and why. I was very impressed with his knowledge. He was excellent. He advised we need a crew to dig up the pipe to the tank. Jay and Cody came out and dug up the pipe and inlet access and found clog mixed with tree roots. They cleaned everything up and all is working. Thank all of you guys for your help. I would recommend all them !"

Septic Tanks FAQs, answered by experts

Yes, you can adjust your well pump pressure relatively easily by yourself. You’ll need to remove the cover from your pressure switch and adjust a nut that controls cut-in pressure. Learn more about how to adjust a well pump pressure switch with a step-by-step guide to setting your water pressure.

If your well pump is running continuously (meaning without turning off or stopping), it's a sign that your well pump is starting to break down. The length of time your well pump should cycle is dependent on many factors, like the tank size, pressure setting, and even the amount of water in your well. Generally, your well pump should cycle, or go from running to not running every few minutes.

Certain foods are easier on your septic tank than others. Septic-safe foods include yogurt, fruit, cooked veggies, and bread because these items all break down relatively easily and can pass through your system safely. Rotten tomatoes, specifically, are actually good for your septic tank because they can increase the amount of good bacteria in the system. 

With proper maintenance, most types of septic systems—including mound, evapotranspiration, and constructed wetland systems—can last up to 40 years. To keep your system running as long as possible, follow basic septic tank upkeep guidelines, like pumping your septic tank every three to five years and only flushing human waste and toilet paper.

A submersible pump should be at least 10 feet from the bottom of the well to minimize the risk of the pump drawing debris into the well water. Submersible pumps work best for wells that are 25 feet deep or less. If you have a deeper well, choose a jet pump instead of a submersible model.
