Sump Drain Placement Advice

[skyrne_isk]

Can anyone take a look at the proposed setup for the drain on my sump? I want to place a bulkhead as low as possible on an acrylic sump that will take up the entirety of the available space in the stand. In the attached picture, the gray rectangle is the 2 x 4 that will make it impossible to go all the way to the bottom, the next piece is the skin of the stand. I would like to use an elbow on both sides of the bulkhead to extend the reach of the drain lower and to allow the ball valve room to turn. The idea here is to allow as much water change as possible (the entire sump if I can swing it) by only turning the ball valve. The drain will go through the floor into the basement below.

Does this look good or any feedback in general? If anyone has taken this approach before, would appreciate input.

Anyone?

That looks like it should work fine.

I haven't done it that way, I have a manifold off of one of my return pumps with an open spot and just pump the water out for the water change.

Can you show me the manifold? I considered doing it that way but wondered about valve failure or head loss.

Sure here are a couple of pics. It's just PVC glued together to make a manifold.

The closest open barb on the top is the one I just push the drain hose onto, I open the ball valve and it pumps the water out. The open barb behind is now connected to my UV.

Clever! Did you go with a uniseal in the wall of the sump there on the lower-right or a bulkhead? Is that a drain?

I used bulkheads, they're installed backwards from the usual to save room in the cabinet. That's one of my returns. I use 2 return pumps, 1 pick up is there and the other is behind the sump directly across, you can see it in the top pic, where the 2 90s are there in the sump. I have the returns, in the tank at 7 different points to really break up the flow, 2 of them are on Moceans. 1 pump goes directly to the tank via 4 inputs into the tank, and the other goes through the manifold and after powering everything from that into 2 returns into the tank on the Moceans. The only issue I'm having is I have no baffles in the sump, and if I turn the flow up all the way I get microbubbles in the tank because the flow through the sump is too fast.

More info than you asked for, but I like talking about it. LOL
