Well, last night while replacing about 100 feet of 1" rigid copper with 1" pex-al-pex, I managed to cut into another 3/4-inch pex line with my Sawzall. I didn't notice it until I tried to pressure the system back up. Fortunately, I was able to isolate the 3/4-inch line and keep on truckin' with the 1." The new pex works great, by the way. Anyway, my first thought was to cut out the damaged section and use a couple of connectors to bridge the gap with a piece of copper. However, I don't have any of the couplings, so I would have to order them from Michigan. But it seems like a shame to spend something like $25 to fix one lousy hole, plus I'd rather not wait. So now I'm thinking about trying to patch it. I'm thinking maybe a piece of EDPM rubber with a couple of hose clamps, or maybe a piece of the pex, cut down the middle, and then laid on the hole and hoseclamped tight. I don't know. A Sharkbite fitting won't work on this kind of pex (wrong OD), and I'm not sure I want to start messing around with glue. Any thoughts, observations or (polite) suggestions?
