"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 can honestly say, Miguel is the best in its class! There were multiple plumbing jobs that needed to get done in my house from changing sinks, to shower heads, bathrooms and leaks that needed repair asap. One call to Miguel and he promptly came to the rescue! We loved how patient he was explaining the many questions we had in detail, despite all the jobs I’m sure he had to go to next. Because we are so satisfied with Miguel’s work, we recommended him to our entire family and friends which he has done many jobs since. If you are looking for a plumber, got leaks, need hardware changed or looking for upgrades I assure you Miguel is your guy! Best pricing around, offers expedited services and someone you can trust!"

Septic Tanks questions, answered by experts

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.

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 tank is an underground container that collects and holds wastewater until it’s sufficiently filtered and broken down. It treats wastewater by separating waste so the leftover liquid can travel into the drainfield where the soil and gravel eventually filter and purify it. This process naturally eliminates bacteria, viruses, and other contaminants.

The size of your septic tank plays a role in determining the proper size of the drain or leach field. As a general rule, you should have 1 square foot of drain field size per gallon of septic tank capacity. However, you could install a leach field that’s as much as 2.5 square feet per gallon of septic tank capacity. Most professionals determine the right septic tank size and drain field size by the number of bedrooms in the house. A three-bedroom house needs a minimum 1,000-gallon septic tank, for example.

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.
