My maintenance man comes tomorrow. I've asked him to move my GD air switch a few inches from the granite counter top to the wall. That way I'll use the hole in the granite for a second soap dispenser which I really want. He says the switch has a screw in the back and he's not sure how to mount it to the wall since he can't get behind it. He wants to see a picture of one mouunted on a wall then maybe he'll figure it out. I've seen a photo here before and that's where I got the idea but now I can't find it. Please help. He'll be here tomorrow. Thank you!!!
