Next time you have a a second any chance you can take a picture and let us know what model you got sounds like a great upgradeI was tired of replacing the float switches so I sealed the holes and threaded some machine screws into the side of the shower box like studs then installed a Whale Electronic float switch on the studs. If it needs to be replaced I don't need to remove the screws from the bottom of the shower box and get it completely dry to seal it. I haven't had to replace it yet and I was replacing the mechanical float switches on a regular basis.
