"They did a good job and followed up quickly to install a riser. Good service at a good price. BUT... I was a bit skeptical of their recommendation for a new filter and expensive turbo cleaning of the septic field/components. I declined the recommendation. The septic field isn't showing any signs of a problem (soggy/soft ground). I might regret it, but I suspect they were needlessly upselling me."

"Septic system was full and back flowing into the basement. These guys came out within a day, located the tanks within minutes, found the problem and came up with a solution! They came by a couple times afterwards just to check the area and make sure everything was still draining properly. Very prompt and professional! Great job guys!"

"It is a privilege to give William Parrish Plumbing my highest recommendation. Our project included drain/flush of a tank-less hot water system and repair of a cracked toilet valve. The work was performed by Pedro who was personable, knowledgeable, and a true craftsman at his trade. He presented several work options so I could pick the service best meeting my needs. Pedro was efficient and extremely clean. You can't go wrong with these guys."

"This company is top notch! We got recommendations from Angi’s list and received several estimates. This company was highly recommended so we contacted them. The technician arrived on time and did a very thorough job. He explained the process in as much detail as we wanted. He even kept going in a pouring down rain storm. His price was the best we found for the job. He was very courteous and friendly. He went above and beyond. Please hire him! You won’t regret it."

Septic Tanks FAQs, answered by experts

For the most part, choosing between 30/50 psi and 40/60 psi is based on your water-pressure preference. However, it can also depend a little bit on your house—if you have older plumbing, a lower water pressure can be easier on the pipes (and a bit more gentle on your well pump). 

The lower 30/50 pressure is usually enough for a single-story home, but you may want 40/60 if you have multiple stories, as the extra pressure helps water flow smoothly up to the second floor.

Most professionals recommend that a deep well pump shouldn’t run more than 10 hours consecutively before cycling off. Overworking the well pump beyond the recommended amount can prematurely wear out your pump and burn out the motor, which means replacing it more often than you otherwise should need to. Your well pump should also come with the manufacturer’s use and maintenance recommendations that are specific to the model.

Regular checks of pressure tanks, testing water quality, and cleaning intake screens.

The easiest thing you can do to prolong the life of your septic system is to adopt septic-safe practices. This includes not flushing non-biodegradable items, chemicals, or excessive grease down drains and scheduling regular septic tank pumping to prevent buildup. It’s also important to fix plumbing leaks promptly and to practice water conservation to avoid overloading the system. To maintain your drain field, avoid heavy vehicle traffic and plant shallow-rooted vegetation in the area. Most importantly, invest in routine inspections and maintenance to detect and address issues early.

Septic drain lines (or leach lines) are typically buried between 18 and 36 inches underground, and should be at least 6 inches below the surface. These pipes are perforated and surrounded by filtering materials like sand or gravel. Burying the lines at this depth helps minimize odors and allows bacteria and other biological processes in the soil to effectively treat the wastewater. Burying lines too close to the surface can cause issues unless the soil is very compact and stable.
