Heath,
Years ago while working in Atlanta, we had a firm come out and clean some drains for us. All they used was the nozzle you referenced from Precision that was hooked to a 3/4" high pressure line. Not sure what results you would get hooking it to the irrigation. I want to say theirs was hooked to something similar to a pressure washer. I remember they stuck the hose in the pipe, turned on the water the hose sucked itself in at a very rapid rate until it hit the clog. Once that happened, they would pull it out and let it go back in a few times until the clog was gone, then pulled it out slowly, flushing all the debris from the lines.
