"Had a great experience with Chris Kuper at Basement Detective! My basement flooded from non-stop storms and I needed a sump pump installed along with complete renovation of my basement. They were very competitive in pricing and outstanding in results. Chris even helped coordinate with the contractor doing my basement renovation after the sump was installed to make sure none of the drainage was disturbed by the new work being done. I have since weathered at least 3 large storms and can hear the sump working as needed. Very happy with the results!"

Septic Tanks questions, answered by experts

The purpose of a septic tank is to allow solid wastes to separate out of the wastewater using time, gravity, and other natural biological processes. If your septic tank is too small, it might be overwhelmed by solid waste and unable to accomplish this task—and if it’s far too large, there won’t be enough liquid in the tank to nurture the necessary bacteria to aid in the breakdown process.

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.

Septic tank risers are indeed a wise choice for homeowners. They provide easy access to your septic tank, streamlining maintenance and inspection processes while potentially saving you money in the long term on multiple excavation jobs. With risers in place, you can proactively address septic issues before they escalate into costly problems, ensuring the longevity of your system. Moreover, compliance with local regulations that require risers can prevent fines or penalties, making them a valuable addition to any septic system.

There are a lot of issues that can cause a septic tank to collapse. Those include failing to regularly pump or service it every three to five years, placing too much weight atop the system—by parking your car on top of it or because of a heavy snow buildup for instance—or because of structural damage done by overgrown tree roots.

Yes, states and municipalities require septic tank companies to be licensed, so an unlicensed  individual or company cannot complete a septic tank installation or alteration. Most municipalities also require licenses for septic tank pumping. You should always verify that the company you’re considering for your septic tank project is properly licensed, which you can do by using Angi’s licensing search tool. You should also verify that the company is fully insured to avoid legal issues should an employee be injured on your property.
