I think I held an ez-flo in my hand once. I'm not a fan of jar tops at all. I seem to remember the ez-flow looking much like the irritrol jartop which is not compatible with the flo-pro. I don't believe you're going to find any other valve with replacement parts for the flo-pro. You could always just buy the parts you actually need to fix the valve if it needs parts at all. --
