"When we were having issues with our rentals plumbing, we reach out to Alex and he did not hesitate to come over and find out the issue. Knowing very well we could not do it ourselves, we hired him to get it done. Not only was he courteous and knowledgeable, he was able to fix our backing up problem swiftly. He is very professional, the work he provided fixed our issues in a timely manner and his rate was very resoanable. I highly recommend Cothren Plumbing and construction for any of your needs!"

Excavating questions, answered by experts

Trenches are typically 12 to 24 inches deep and 8 inches wide. However, the required depth depends on the specific project and local ordinances. For example, a French drain may need to be 18 inches deep, while a water pipe might require a depth of 24 inches and a drainage pipe 36 inches. Your city or county may have specific regulations, so it's wise to consult with an excavation professional to determine the correct depth for your project.

If you have a broken sprinkler pipe underground, there will be some signs you can easily spot to locate it and take action. These include leaks, water spouts, flooding, consistently damp areas on your lawn, low water pressure, and grass around the sprinkler head that’s taller and darker than anywhere else in the yard. 

If there are no obvious signs of a broken pipe, you can use tools such as water leak mics, leak noise loggers, audio devices that record leaks, and acoustic testing links. 

Broken pipes can lead to uneven watering, plant damage, and higher utility bills. The longer you wait to fix them the more the repair cost may be.

A perc test can take anywhere from one to eight hours to complete. The total time depends on factors like the amount of excavation required, the depth and width of the holes, and whether multiple test holes are needed. For a single hole, the process of filling it with water and monitoring the drainage rate usually takes less than an hour. Professionals can often complete the entire test in a single day. While it's possible to get results the same day, some companies may take a few days to provide the official report.

Skunk digging looks like a series of small, cone-shaped holes on a lawn or around the perimeter of a home, porch, deck, or shed. The holes that skunks dig when searching for grubs tend to be no more than four inches in diameter and may be up to four inches deep.

Septic drain lines (or leach lines) are typically buried between 18 and 36 inches underground, and should be at least 6 inches below the surface. These pipes are perforated and surrounded by filtering materials like sand or gravel. Burying the lines at this depth helps minimize odors and allows bacteria and other biological processes in the soil to effectively treat the wastewater. Burying lines too close to the surface can cause issues unless the soil is very compact and stable.
