What you can’t see in the photo is the pair of gravity boots attached to the ceiling. And all you have to do to use the door is hang upside down and work the handle. Or, learn how to hang a door right-side-up.
Looks like they pulled the guts out of the first valve, and then connected another valve to it? I guess you’d have to control the initial valve from an interior shutoff?? Seems like replacing the old hose bib would’ve been the right choice.
Instead of moving the electrical box, or buying a light fixture that allows the door to open, or getting rid of this handy storage space for nothing… Another example of a DIY’er who’s obviously single.
