Travis - do you have any other plumbing after the h2overflow or does it just go straight out the back and down to your valve by your sump? It doesn’t whirlpool with air?

That’s what the valves are for. You close them off partially so that the water draining down them is fully siphoned. This way there is no air and no noise. You cannot hear anything from my setup, even when you’re standing right next to it. Yet, I am running it at about 1500 gph.
Thanks. I might try something like that but with a diy weir.
Tell me a little more about your returns. What is aquarium specific parts vs common plumbing? Where did you drill your anti siphon hole?

Do you think one of your drains could run the full 1500 gph on its own? Wondering what you think your 1 1/2 inch lines could flow at full siphon.
One design I kind of like has a hole drilled in the bottom, with a bulkhead that runs a pvc pipe up to top of tank with holes drilled. Another pipe bigger sized, covering it with holes drilled in both top and bottom. This way it sucks overflow from both top and bottom. It takes up some space but pretty cool design imo
I don’t think there is anything different between aquarium specific plumbing and regular plumbing other than the color. Many people use regular PVC in their aquarium plumbing.
As for the flow rates, each of the H2Overflows is rated for 1200 gph, but I don’t think that is a rating for full-siphon. You might be able to get 1500 gph if it’s a full-siphon setup, but I’m not sure about that. I’d just recommend going with three 1.5” bulkheads. If you’re going to drill two holes, it’s not hard to drill a third.
