How To Locate Septic Tank Field Lines. The lid of the septic tank should be visible. Once we can find the septic tank itself, the septic tank outlet defines the location of the effluent drain line that leads to the leach field.
The water level should always be at the level of the drain line connecting the septic tank to the leaching field. Next step is to find the back of the septic tank and dig down to find the pipe that runs out of the tank into the drain field. Find the tank’s end opposite the house, then follow the drain lines to the leach field.
In some cases, a septic tank riser may have been installed and that will make it easy to locate your septic tank.
If you have just purchased a property and know that there is a septic tank but don’t know precisely where the tank is located, you will need to locate it. Look for visual clues first. So, how to find septic tank field lines? A septic probe can also be used for determining how to locate septic tank field lines.
