The present invention discloses a system and method for cleaning the field lines of a septic tank system. The field lines are outflow pipe fluidly connected to the septic tank. To the field line, there is connected a first pipe and a second pipe or a flush pipe and a vacuum pipe. One of the pipes directs cleaning fluid, usually water, into the field line while the other removes the cleaning fluid and other material from the field line through the field line. A third or valve pipe is added between the first and second pipes and the septic tank. A valve can be placed into the third or valve pipe which is used to close the flow of fluid between the septic tank and the first and second pipes.
