"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

Adding a thin layer of dirt over a septic drain field is fine, especially if soil erosion has occurred. However, adding too much dirt can compact the soil, reducing the drain field’s ability to absorb and filter wastewater properly. Avoid using heavy clay soil, as it can prevent proper drainage. Instead, use a light layer of topsoil and plant grass to help with soil stability.

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.

A mound septic system, when properly maintained, can last between 20 and 25 years on average—though some last longer or malfunction sooner than that. The most important part of maintenance is getting an annual inspection of the vital parts of the system to ensure they’re in proper working order and not too backed up with sewage.

Expect to take at least a day to drill your own well by hand. For a 500-foot well, this could take even longer, depending on the makeup of the soil and the terrain you are drilling through. Other factors include your physical strength and overall fitness level and the weather conditions you’re working in.

The average lifespan of a deep well pump is between 15 and 25 years, after which you’ll have to replace it. Several factors can affect the lifespan of a well pump, such as the quality of the unit. Proper maintenance and repair can also help extend your well pump’s lifespan as well as keep adequate water flow and pressure throughout your home.
