Today we got our well waited for toilet, it is a Kohler Kingston which is a wall hung toilet without a tank, it requires a flushometer. I got a Sloan royal sensor operated flushometer for it from eBay. I reinforced the wall studs with 23/32″ OSB, and as you can see the carrier is too big to fit inside one wall, it required two walls spaced apart to fit everything inside. I hooked it to a 1″ copper line and have had some pressure drop during high flow when flushing, I think I’m going to put a second pressure tank behind it to help, but it’s working good enough for now.
