Sump room manifold design

[bluegrassreefguy]

I currently have a manifold in my sump room that is all 3/4 pvc with ball valves

A red dragon 10m3 2650 gph supplies the manifold from the sump below

The manifold supplies water to
Display tank
Carbon and gfo reators
Skimmer water height level
And Refugium

I just recently got a new external pump mainly because the red dragon wasn't providing enough flow for the entire setup

The new pump is a dart hybrid gold rated at 2400/4300 gph. The input is 2 inch and the out put is 1.5 inch

So I'm thinking I need to build a different manifold since reducing the plumbing to 3/4 that quick I believe will cause issues

If I do end up redoing the manifold I would like to go with a better looking scheme something like this all orange and grey! Mainly because everyone else does grey and red and plus I have recently acquired a lot of apex things and it will look very uniform and clean

What are you opinions comments questions

Looks like orange schedule 40 pipe with schedule 80 fittings. A good combination. I recommend either adding unions below the gate valves, or replacing with Cepex union ball valves. For maintenance ability.

Thanks for the suggestion bighildy53

Want flow? Get diameter. I'd go with 2" from the outlet. Yes, size it up. Run 2" until you tee off your manifold where you reduce to smaller sizes as needed.

Look at municipal water supplies. There are 12"+ water mains that eventually get reduced to 1/4" in your sink because of reduced demand.
