I have my return lines leaking. Currently plugged and just returning to main drain. Has anyone used the ppg1 and ppg2 system to stop leaks in the pipe. Watched the video and it looks like it just gets pumped in and held for 45 minutes then pumped out. No digging required. The pipes are under concrete so it would be a major ordeal to dig for repair.
