"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

A septic system can fail for various reasons, and most commonly, excessive water use or sudden surges in wastewater can overwhelm the system's capacity. Neglecting regular maintenance, like tank pumping and inspections, can also lead to clogs, leaks, and eventual breakdowns. Other issues that lead to failure include age-related wear and tear, root infiltration, improper disposal of non-biodegradable materials or chemicals into the system, unsuitable soil conditions, physical damage, and even environmental factors like flooding or soil erosion.

While dry wells can be effective for managing rainwater, they have several disadvantages. They can become clogged with sediment, especially after large storms, which reduces their effectiveness and can be difficult to clean. Dry wells are also not suitable for all soil types; they will not function properly in soil with low permeability. Additionally, if a dry well is not large enough to handle the amount of rainfall in your area, it can overflow. For gravity-flow models, the water may disperse very slowly, depending on the well's depth and the soil's permeability.

While you can drain water softener backwash into a septic tank, doing so may cause several problems. One problem is that increased sodium chloride levels from water softener backwash can kill septic tank bacteria, decreasing the effectiveness of this wastewater treatment system. Another issue is that large calcium deposits can eventually stop up the drain field and lead to poor drainage. 

If you aren’t sure if you have a septic tank or a cesspit, you can check your property records or inspect your drainage system. A septic tank has an outlet pipe that allows liquid to drain into a soakaway or drain field, while a cesspit is a sealed tank that requires frequent emptying. If you notice a manhole cover and no nearby drainage field, it’s likely a cesspit. Signs like slow drainage or a frequent need for pumping can also provide clues. A professional inspection is the easiest way to confirm if your home runs on a septic tank or cesspit.

A septic system inspection costs $100 to $200. Doing so can spot issues early so you can plan for necessary repairs ahead of time and save yourself the issue of a backed-up septic tank. Some septic tank repair professionals do an inspection as part of their yearly maintenance on your septic tank if you choose to pay for that service, but you should shoot to have a septic system inspection completed at least once every two to five years.
