"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

Your septic tank naturally contains the good bacteria it needs, so you typically don't have to add more as the system produces them on its own. However, if you wish to replenish the bacteria, you can use natural methods. For example, you can add three rotten tomatoes to your garbage disposal or flush 1/4 ounce of active yeast down the toilet every three months. While store-bought septic enzymes and chemicals are available, many additives are unnecessary and may even harm your system. The most effective way to maintain a healthy bacterial balance is to avoid using chemical drain cleaners, which can kill the beneficial bacteria in your tank.

We’ve explained how deep-rooted plants can damage a septic tank from the outside, but plenty of things can ruin it from the inside, too. For example, flushing bulky items (like paper towels, diapers, and wipes) can clog your septic tank. Cooking oil, grease, and household chemicals can also harm your system. And since a new septic system costs between $3,460 and $11,450, it’s worth following these guidelines.

There are a couple of ways you can determine the depth of your well. One method is to use a device called a well sounder. This tool has a long measuring tape containing a sensor to alert you once the end reaches the water. 

Or you can DIY it by using a long tape measure with a half-filled bottle of water attached to it. Lower the tape measure into your well. Once you feel tension on the tape, you’ll know the bottle has reached your static water level. This will give you an approximate idea of your well’s depth.

Septic tank odors can happen because of a few different issues with your septic system, such as a full tank, clogged drains, or blocked venting systems. Not only is a smelly septic tank pretty unpleasant, but it can also pose a potential hazard to yourself and your home. Toxic fumes could be hanging around, or untreated wastewater could be harming the environment.

Most well pump pressure switches have a factory setting of 30 to 50 PSI. There’s some flexibility with this if you’d like a lower or higher water pressure, but remember that it should sit 2 to 3 PSI above your well tank’s general pressure setting.

The inside of your pressure switch cover will usually indicate minimum and maximum settings—going below and above the numbers might damage your well pump.
