"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

Unfortunately, yes. If your well pump continues working when the flow of water is completely blocked, the motor will burn up. The energy has nowhere to go, thanks to the blockage, so it turns inward. The end result? A ruined well pump and a depleted bank account (once you shop for a replacement.) 

There are a lot of issues that can cause a septic tank to collapse. Those include failing to regularly pump or service it every three to five years, placing too much weight atop the system—by parking your car on top of it or because of a heavy snow buildup for instance—or because of structural damage done by overgrown tree roots.

Drain fields often include three to five trenches that are 18 to 24 inches deep. The pipes connecting the drain field to the septic tank will be placed between 12 and 18 inches deep, and the field as a whole will be about 100 feet long.

With regular servicing and general upkeep, both a well pump and pressure tank can last for years. The average lifespan of a well pump is around eight to 15 years. A well pressure tank can last from seven to 10 years. How long a well pump and pressure tank lasts also depends on a variety of factors such as type, size, material, and brand.

Yes, it is possible to drill a well by hand, but it calls for a good deal of physical labor. Drilling a well by hand is best suited for softer soil, and it may not be possible through rockier terrain. For wider and deeper holes, companies with professional equipment make the job much easier.
