I have some PEX with Sharkbite connectors routed around a joist. There is some tension where the PEX joins the copper plumbing. Is it too much?
I agree that these junctions do not look like they are under too much stress. I have only once had one of these connectors fail, and it did so within 24 hours of installation. However, if I were concerned about leaks, I'd replace that elbow and those tees with PEX connectors - more secure and much cheaper.
