Hello I'm installing the above and looking at a picture of the design an dit looks to have three gate valves on the the three drains. Is this required or is one on the main drain enough?

Only the siphon line needs a valve. Water traveling the open channel line is just a byproduct of what's left from the siphon.

Yeah, but they aren't necessary. If you were to read the entire thread with thousands upon thousands of posts, you'd eventually find where it's discussed.

If I could change one thing about my Bean drains on my 150, I'd make my siphon a 1" line instead of 1.5". It would have saved a bit of expense on my plumbing and I wouldn't need to have my gate valve closed so much.
