Como Aquaculture Air Flow Control 3 Way Aquarium Lever Valve Pump

Works perfectly for my needs, strong quality construction, a nice weight to it and precise control levers. Two thumbs up!

No complaints here. I prefer metal valves over plastic just because they're more durable. Now that I think about it, I do have some valves with knurled and threaded adjustment knobs, and the ones like this with the levers can be a little touchy and harder to make fine adjustments with, but good over all, no leaks.
