"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

Wells should be at least 100 feet deep for drinking water, but they may need to be deeper depending on the local geology, water quality, and your household’s water usage. Work with a qualified well drilling professional who can assess the appropriate depth for your well and test the water before drinking it.

Normally, when your well pump turns on or off, you’ll hear a small click. This isn’t anything to worry about, but it can be a problem if it’s clicking continuously. This can indicate that the well pump is short cycling—the pump continuously turns on and off.

This can wear out the motor and provide uneven water flow. If this happens, you may need to get it looked at by a well pump professional to see if you need to repair the switch or pump.

While a traditional septic tank requires a leach field for wastewater disposal, it is possible to have a septic system without one. Some alternative systems, which are often used when there isn't enough space for a full-size leach field, include mound systems or sand filtration systems. In a conventional setup, the leach field is essential because it's where the wastewater goes after leaving the tank.

Well water is often assumed to be hard because of its high mineral content. Hard water can lead to mineral build-up in your pipes and appliances. You can manage hard water by installing a whole-house filter system. These systems can help extend the life of your water-reliant appliances like your hot water tank and dishwasher. 

Septic tanks appear full after pumping because the liquid levels have returned to normal. If you can see the pipe, the tank is empty. However, heavy rain can cause septic tanks to fill faster than normal. You might also have leaky pipes or faucets, causing extra water to drip down the drains and into the septic tank.
