Water supply pipes need to be supported to prevent movement. This is usually done with metal straps fastened to joists. But why bother with a strap when there’s such a convenient garage door chain rail available?
Notice the careful application of several layers of duct tape to cushion the copper pipe from the vibrations of the garage door opening and closing. With no other pipe supports nearby, it will only be a matter of time before all the vibration will cause damage to the water pipe.
The question comes to mind: Which came first? If the pipes were installed after the garage door opener, why wasn’t it positioned a little higher and properly supported? And if the garage door came later, why wasn’t it installed an inch or two lower to clear the pipe?
