If you're not sure where your D-Box or Septic Tank openings are located, we can help you find them.
Have your septic tank manholes become buried? Here is what we can do for you. We place an electronic transmitter attached to a flexible cable line and insert it into the sewer at a pipe opening, clean out, or pipe end and manually pushed it down the pipe. The transmitters route and location in the pipe is monitored above ground using an electronic locator indicator. The ground can then be marked at intervals or mapped. We can also ascertain the depth of the pipe from the readings and by combining video camera inspection we can tell what is going on inside the pipe so we know how deep the pipe is and where we will have to dig if a repair is indicated. This locating or mapping can allow you to find any existing lines to tie into if needed or it can simply be useful for damage avoidance.

 When using the Electonic Pipe Tracing tool we are able to pin point the exact location of where to dig in order to eliminate the need to dig up more than is necessary. Having the ability to pinpoint the location of the damaged pipe particularly on long lengths of sewer pipe runs saves time, money, and your lawn. With Dennis Diffley & Sons Inc. electronic pipe tracing, there is never any guess work. We know where to dig when there is a problem and we can tell which way the pipe may be routed when there is no print available to guide the technicians. We provide this service for both commercial and residential customers. Here are the Benefits of Electronic Pipe Tracing :
