Q: What are signs that my septic tank is full?

• <div><p>Some signs that a septic tank is full include wastewater or even sewage backing up into drains in the house, foul smells coming up through the drains or around the yard, pooling water in the yard, spongy soil underfoot around the septic tank, gurgling noises in the pipes, or grass that looks lusher or greener than normal without any new lawn care services.</p></div>

Q: How long does a well last?

• <div><p>The average life span of a well is about 30 to 50 years. Several factors can affect a well&rsquo;s lifespan, such as its size, construction quality, water demand, and regular maintenance. Environmental factors, including droughts and earthquakes, can also have an influence. Drilling deeper, getting professional maintenance, and regulating your water usage can help extend your well&rsquo;s lifespan.</p></div>

Q: How does a septic tank work?

• <div><p>Unlike an urban sewer system that runs wastewater into a central drainage system, septic tanks are a house-by-house system. They are the ultimate destination for all your house&rsquo;s wastewater&mdash;from bathtubs, showers, sinks, toilets, and washing machines. Wastewater flows into a tank buried in the ground outside your home, and then water runs from the tank to a drainage field using sloped pipes.</p></div>

Q: How deep are septic lines buried?

• <div><p>The <a href="https://www.angi.com/articles/how-deep-is-septic-tank.htm">depth of a septic tank&rsquo;s</a> drain lines is between 18 and 36 inches underground. These pipes are filled with perforations and surrounded by sand, gravel, or a combination of both, as both materials help filter wastewater. While some pipes are buried closer to the surface, this can create problems unless the soil is compact and doesn&rsquo;t shift much. </p></div>

Q: What psi should my well tank be at?

• <div><p>When testing the pressure of your well tank, the psi should be two below the cut-on pressure. For example, if your tank is set to 40/60, then your pressure should be at 38 psi. </p></div>
