I have not used one but that looks like a functional piece that I would install. Currently I use a valve and hose that I attach to my raw water intake line which accomplishes the same task. However, it requires undoing one side of the raw water line. As far as flushing or running the engine while connected it seems very effective. Cheaper to build your own but the Perko seems very tidy and more convenient.
I've mostly quit using mine as I just drain my cooling system thoroughly for winterizing, and don't generally need to operate the engine while on the trailer anymore.
