"I just pay $75 you never know who's going to come out. They do everything electrical. Just about everything is covered except the septic tank. I had an air conditioner replaced. It went great, all I had to do was pay for the freon. He didn't charge e more than what was needed."

Septic Tanks questions, answered by experts

Mound systems can fail if foreign objects are flushed into the septic tank, the septic tank is backed up with solid waste (sludge), if wastewater floods or seeps from the mound, or if any part of the system is clogged. To prevent this, only flush toilet paper and your normal “business” down toilets, and get a septic inspection at least yearly.

A septic tank always has some amount of liquid in it—which should usually be 8 to 12 inches from the top of the tank. If the liquid level is higher than that or is overflowing the drainage pipe that leads out to the leach field, the tank may be too full and in need of pumping.

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.

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.

There are a variety of different types of septic systems that can work in your home—such as conventional anaerobic systems, chamber systems, drip distribution systems and mound septic systems. All of them work using natural processes to break down solid waste and effectively treat wastewater without needing to be connected to a city sewer system. Which type of septic system you need will depend on characteristics of your property like how high the bedrock is or groundwater table is. Different types of systems come at different costs to install.
