"Xtreme Excavation and Grading was fantastic, my sewer pipe was backing up so i ran a camera and come to find out it was packed full with roots and waste, so I googled up some companies and got a couple quotes but the I called and spoke with Brandon (the owner of Xtreme) and him and his guys didn’t waste any time!! He told me the price (which was extremely reasonable nearly half as much as the other 2 places i called) came out the next day and fixed my issue, Very friendly and knowledgeable and they did great work!! I will definitely be keeping them in mind for future needs"

Septic Tanks FAQs, answered by experts

Septic tanks aren’t bad for the environment as long as they receive proper maintenance and attention. This means staying up-to-date with professional septic system inspections and septic tank pumping. Without regular maintenance, parts of the septic system could break or stop working, potentially letting harmful waste into the soil and groundwater.

How deep your septic system needs to be into the ground depends on several factors. In extremely cold environments, the tank needs to rest below the maximum frost line, which can be up to six or eight feet deep. The standard burying depth for most systems is between a few inches and four feet below ground level. Depth can also depend on the slope of the landscaping and other property variables. 

Most well pump pressure switches have a factory setting of 30 to 50 PSI. There’s some flexibility with this if you’d like a lower or higher water pressure, but remember that it should sit 2 to 3 PSI above your well tank’s general pressure setting.

The inside of your pressure switch cover will usually indicate minimum and maximum settings—going below and above the numbers might damage your well pump.

When your septic system is failing, you’ll probably smell it. Common signs of a septic system failure include sewage odors in the home or around the yard, flooding in the yard above the septic tank or in the leach field, and wastewater or even raw sewage backing up into your home’s drains.

There is no standard depth for burying a septic tank; they are typically buried anywhere from 4 inches to 4 feet underground. The final depth depends on several factors, including the depth of your main sewer line, the height of the bedrock, soil type, local regulations, and the property's landscape. If you plan to grow grass or plants over the tank, a depth of at least 4 to 6 inches is recommended. Deeper tanks can be more difficult to locate, but a septic professional can help find it for you.
