I understand that the maximum bending radius for 1/2" pex is 5". In my plan for a project, I want to run pex from a shutoff valve and then have it double back to supply a spigot outside (the copper supply is not in the ideal location). This would all happen within a joist bay of about 14 1/2". Typing it out is leading me to think it might be too tight given the joists are 2x8" and a 5" radius means a diameter of 10". Regardless, I'm wondering if anyone has had any experience turning pex back in tight spots and if there are other solutions my limited experience is hiding from me. I am aware of one solution to use 90* connectors but I want to create the fewest connection points at the least cost. That would be the last resort (if not maybe the only resort). Thanks
