"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 FAQs, answered by experts

Drilled wells have a pipe sticking up that’s covered in a plastic or metal casing. On the other hand, a dug well will look like a big hole in the ground and is more similar to what you’d see in a fantasy or Western movie. If you want to be sure, contact the city for documentation on your property’s construction and excavation history. 

While abandoning a tank without treating it and following strict rules is illegal, there are several other ways to dispose of an old septic tank. One standard method is to pump out and crush the tank where it rests and bury it in the soil. Another is to remove it and transport it to a landfill. Finally, if abandonment is the best option, your contractor must pump out the tank and fill it with inert material, such as sand or concrete, depending on local regulations.

A gurgling toilet usually doesn’t mean that your septic tank is full. If waste can’t drain into a full septic tank, you’ll see water and sewage backing up into your fixtures, but the air that causes gurgling is a result of poor venting. You are more likely to have a clog in your vent stack or a damaged air admittance valve.

Although air in your water lines won’t affect the overall quality of your water, it will lead to problems with your well water system if not addressed. Over time, too much air in your water lines can create blockages in your pipes, cause insufficient water flow to your taps and appliances, loosen pipes, and potentially damage important components of your well including your well pump and pressure tank. 

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.
