Starting more of the supply plumbing work in my bathroom. Working on the tub valve some more. I will have the valve between 2 studs at a 32" height, with 1/2" supply lines running down each stud. How is the valve supported? Does it just rest on the copper lines, and the copper is supported wherever it turns to go horizontal? Or is there some way I should be supported the vertical drops of the copper supply lines which would in turn support the valve? Anyone have any pics of a bathtub rough in for reference?
