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.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?
How long have you had it set up?I have the eshopps large over flow on my 75 it’s does 1000gph . When I build my big tank I think I’m just going to get two of the eshopps large over flows that will be close to 2000 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?
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.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.
