Surprisingly I can't find much information here on such a subject.
I am [re]plumbing using [1/2" and 3/4"] PEX under floor joists and will need to make 90 degree course changes occurring between two adjacent floor joists: piping running parallel along one joist then needing to turn to run perpendicular to the next joist). I am NOT using elbows (minimizing connections under my floor).
Based on the distance between joists (16" OC) I shouldn't need any supports, but... Will the piping hang up in the "air" w/o any mid support?
And what supports should I use for the piping at each adjacent joist? I have a concern about the piping wanting to apply straightening force against the supports. I suppose that a 90 degree bend support would significantly reduce such strains but reviews/comments on these supports seems really less than comforting: "kinks piping," "hard to hold pipe in" etc.. I am thinking that perhaps padlock type supports would be best as they reply on only one fastener to the joist and that would allow the bracket to twist a bit with the pipe. [I'd use the same brackets for the parallel runs/along the joists and butterfly ones for perpendicular runs/across joists.]
