"I dealt with John and Dave. They were always very punctual, the proposal was specific it clearly stated what they would be doing, the size of the septic tank, overflow, main line and the cost. It was all done to code. They were polite, responsive and answered all my questions even after the work was completed, I wish I would have realized or been told how extensive the area that was disturbed would be. I would have removed more of the plants."

"I rated this company Top Notch because they are! From start to finish, friendly, respectful and professional. Christine in the office was delightful and got back to me each time she said she would with ETA. Jimmy did the work which hadn't ever been done since we moved in in 2000! He uncovered not one, not two, but five lids - cesspool plus two overflows and septic tank plus one. He sucked out the gunk, rotored out our lines and was patient, efficient and very pleasant. Explained everything that needed to be done. Took 2-3 hours of work. He cleaned up our backed-up tub and everything works great now. We would DEFINITELY hire them again. Highly recommended!"

Septic Tanks FAQs, answered by experts

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.

Modern septic tanks have two lids: one that covers the inlet where wastewater flows into the tank and one that covers the outlet where the treated water flows out to the drain field. However, older septic tanks installed before 1975 may have only one lid. Because septic tanks last 20 to 40 years, if yours only has one lid, it may be time for a replacement.

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.

You can add three rotten tomatoes or 1/4 ounce of yeast to your septic tank to speed up the decomposition of sludge. You can add the tomatoes by way of your garbage disposal and the yeast by way of your toilet. You can do either of these additives once every three months as needed.

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.
