Livewell...I think I'm on the right track.

Alright, I'm finally getting around to putting the console together on my Weldbilt project. I just finished mocking up the drain/overflow portion. I need some opinions though...it seems to be a little too complicated. The ultimate goal is to have the drain and the overflow tied in together, going to a through hull fitting below the waterline on the port side. Is there a way to simplify this? I'd like to have the fewest possible connections to cut down on maintenance/leaks.

Here's a side shot of the system.

And mocked up in the console.
