"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

There are many reasons you may want to extend the depth of an existing well or drill a new, deeper well on your property. A deeper well can tap cleaner water sources—shallow water may contain more contaminants. With a deeper well, you’ll also have an easier time reaching the water table depth (the level at which underground water is found) and can get past tricky soil conditions. 

Plus, if your local building code requires a minimum well depth for safety and environmental standards, you’ll meet the code by digging a deeper well in the first place.

You can put yogurt in your septic tank, but it will not increase the bacteria in your septic tank. In other words, it won't harm your tank, but it won't get rid of a septic smell or boost the performance of your septic system. While yogurt contains helpful bacteria, you would need to buy an extraordinary amount of yogurt to make any difference. Adding yogurt is not a helpful or cost-effective strategy.

Ideally, you should conduct a mechanical inspection and a bacterial or well water inspection yearly. While you might be able to push it off to every other year, it’s best to have peace of mind, especially when it comes to something that you use so frequently. 

If you experience repeated gastrointestinal illness in the household, it's important to test the well water more regularly for quality and cleanliness to check for bacteria.

Options include submersible, jet, and centrifugal pumps. Choose based on water needs and well depth.

Most deep wells can be expected to last somewhere between 30 and 50 years. This assumes that the well and all of its components are properly maintained on a regular basis. During this time, it is unlikely that modern deep wells will run dry over the course of their typical lifespan. That is one of the biggest benefits of digging a deeper well.
