Added this in 2006 on kitchen remodeling. Great kitchen accessory. Valve matches kitchen appliances and sink valves. Hot water heater part died. Went to replace and the model we had had been discontinued. Customer service rep provided the replacement model number. I ordered it. Install took less than 5 minutes. Screw holes lined up and all plumbing fittings fit perfectly. Didn't have to run new valve plumbing! Thanks insinkerator. Happy wife happy me.
