Another question - how to support Pex between studs?
Had to add supply lines in powder room where builder didn't put them in. Stud in 36" wide wall to right of waste - so I cut drywall to right of the stud, drilled down through 2x4 and plywood about 3.5" to basement to run two 1/2" Pex lines to join where supplies are capped off in basement. BUT... b/c of floor joists, ductwork, etc. down below the 2 new lines ended up 4" to right and 9" to left respectively from nearest studs (with the waste on the other side of the left hand stud). Lines are just fed through to cut to length, not connected yet.
So how to I support these lines and make a nice 90 degree bend to come out of the wall? Drywall behind them (wet wall 4" deep in front of marriage wall of modular home), there could be 2x3s behind them somewhere but I have no idea where.
