How to locate blockage in a septic drain field line?

[MichaelSen]

Hi

All 5 lines in my septic drain field seem to be blocked. Other than sending a scope down the line, is there any other method to trace the buried pipe from above ground and locate the blockages? Something like ground penetration radar? The scope tells me how far in it is, but not the actual location

You could use a camera with a sonde and a locator to give you the location.
