"Great! Patrick responded the same day and gave me a quote of $150, as compared to $180 to $375 from other plumbers. He had to snake the pipes twice to clear the clog, but insisted he stick to his original flat rate quote of $150 despite my offering to pay more because he had to snake it twice."

"They showed up on time and got right to work. The actual installation went okay. They, however, did a very poor job of cleaning up behind themselves. Also, when they refilled the hole they dug it wasn't close to being level with the rest of the yard. Instead there was a very visible large mound of dirt. I contacted them a week or so after having the work done, to discuss a concern, and the person I spoke with completely blew me off and dismissed my concern. That is when they lost any opportunity for repeat business from me."

"**To everyone** This is the plumber you want to call !!! Typical FANTASTIC service call from "Knock You Plumb Out Plumbing". Our family was dead in the water, plumbing wise. We could not flush a toilet. Water was rising everywhere and all drains were gurgling. John Harris (owner), and a 2-man crew arrived 30 minutes after I sent a "Help!" E-mail to him. I could not believe he got to my home so quickly. John and his crew went to work diagnosing the problem. John started removing the plug on one end of my sewer system and found that my entire sewer system was under tremendous pressure due to all of the plunging I was doing. Before he started taking any more pipes apart in the basement, he asked if I had a septic system. I told him that I did and he said that my septic tank was probably full. John went out back, took the lid off of my septic system and found that the tank was almost completely full! Thanks to John, I then knew what the problem was and it was an easy fix. I had a septic cleaning company come out within a couple hours, and my house was back to normal. Thanks again John. This was the second time in 3 months he helped me out and I could not be happier. This guy is my only plumber?forever!

"I didn't know how to evaluate the damage my stopped up basement drain was causing. But, Mr. Bailey was great and solved the problem quickly. He even did a little favor for me re: my slow bath tub drain. I would recommend his service; he was personable, professional and informative."

"They called me right away once I submitted the request through Home Advisor and arrived the next day. Work was done quickly. My questions were answered and they will remind me in three years to have my septic cleaned again. Can't ask for more than that! Not sure of the value for the money, did not price around."

Septic Tanks FAQs, answered by experts

If you’re going away on vacation or leaving your home for a long time, it’s a good idea to switch off your well pump and pressure tank before you go. This way you can prevent any damage from unexpected leaks that may occur or unforeseen electrical issues while you’re away.

Depending on the size and location of your septic tank repair job, you may want to let the septic pros finish before tackling other backyard work. However, in some cases, it’s not a bad idea to coordinate between your providers if the timing’s right and your septic repair pro says it’s safe to do so. For instance, if the septic repair work is happening in the fall, you might want to take advantage of the opportunity to prepare your backyard landscaping for winter , or in spring, start mulching the garden beds.

There are a variety of different types of septic systems that can work in your home—such as conventional anaerobic systems, chamber systems, drip distribution systems and mound septic systems. All of them work using natural processes to break down solid waste and effectively treat wastewater without needing to be connected to a city sewer system. Which type of septic system you need will depend on characteristics of your property like how high the bedrock is or groundwater table is. Different types of systems come at different costs to install.

Several things can ruin a septic tank over time, including dumping harsh chemicals (like bleach and ammonia), pesticides, and paint thinners down your drain because they can kill the bacteria in your septic tank. You should also make sure to only flush waste and toilet paper in your toilet—otherwise, you could clog your system.

Trenches are typically 12 to 24 inches deep and 8 inches wide. However, the required depth depends on the specific project and local ordinances. For example, a French drain may need to be 18 inches deep, while a water pipe might require a depth of 24 inches and a drainage pipe 36 inches. Your city or county may have specific regulations, so it's wise to consult with an excavation professional to determine the correct depth for your project.
