"Leo was very helpful and quick to respond. We’re happy with how our 2 bathrooms turned out. Project was completed within the time promised. Our only complaint is that the workers did not clean up very well. But overall, we’re satisfied and we’ll use them again."

"I did not get estimates from other plumbers in the area, so I don't know where my cost fit in a range from others to judge by. I paid $3280.00 for cesspool draining and hydro-jetting the pipe. Otherwise, I liked the service which was prompt, and the plumber courteous."

Septic Tanks questions, answered by experts

The septic installation company must follow several steps to put in a new septic system and leach field. The installer will study your property and determine the best place for the tank and leach field. The site should be away from existing structures, be free of trees, and have proper drainage and grading. Preparing the site for the tank and leach field will require significant excavation work.

To keep roots from growing into a septic tank. However, there are other steps you can take if existing tree roots are getting close to your septic tank. For one, you can install root barriers, which physically block roots from reaching your septic tank. You can also use chemical solutions in your yard or plumbing system to deter root growth.

Neither system is necessarily better or worse than the other, but one of the two might be better for your needs. For example, anaerobic systems are less expensive than aerobic ones and don’t use power to run. On the other hand, aerobic septic systems don’t take up as much space and are typically more efficient than their anaerobic counterparts.

If your leach field becomes clogged or saturated, it can cause several problems with your home's septic system. The clog can cause sewage to back up into your home, leading to unpleasant odors and mess. A backed-up septic system can be a health hazard, particularly if the sewage starts to leach into the ground surrounding the leach field.

There are several ways to fix a saturated drain field, including cleaning out your septic tank, adding enzymes and additives to your drain system, and installing a larger septic system.

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.
