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?

  • FYI, that's a stud, not a joist. You could notch into the stud an inch or so to relieve some of the strain. This will not cause a structural problem. – isherwood Nov 30 '17 at 16:00
  • Ah right. The 2x6 already has a 2" hole through the center for the plumbing air vent, plus I shaved it down 3/4" to make room for the shower base... so even though it's not load bearing, I was worried about removing too much material. Ended up sistering to the right and left of the center 2x6 with some 2x4s for my peace of mind. – hoosierEE Dec 3 '17 at 2:08

I say that the installation is well within the capabilities of shark-bite fittings.

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.
