I just got my new sump up last night with my own version of a ro auto top off. I heard of bad stories of backpressure floats not shutting off and houses flooding. And I didn't want to use a pump. I had bought a Kent RO shut-off but I was leary to use it. So I bought a float switch off of ebay for $5.00, and a solenoid from stcvalve.com for $20.00, I am a lot more confident in this system.
I haven't figured out how to attach photos to posts, so I linked them up from the photo gallery.
