I think my latest effort will be a permanent repair. I located a heavy 2" wide rubber tape that is actually made for insulating and waterproofing electrical splices and is made by 3M. It is very similar to the 1" rubber tape I had already installed but didn't have 100% confidence in because it only lapped a 1/2" each side of the leak. I left the 1" in place since it has worked fine for a couple of weeks and put the heavier 2" on top of it. I was able to stretch it to a very tight wrap. After putting the hose clamps back in place it is likely stronger now than the pipe it repairs. Next I will reinstall the jets and run the air blower to check everything under pressure. After passing that final test I will wrap the hose clamps and fill the hole.
