Drain plumbing with remote sump room

[Mshort03]

Hey guys, I have a 300 display with a remote sump room about 25 pipe feet away in my garage. I am running an abyzz a200. I have two holes in each overflow, one as a 1.5 drain pipe one as a 1 inch dry emergency drain in each overflow. Return over back. When I first put stand pipes in I tried to do durso style and when I would put the "u" part on top it would raise water level in return chamber over the dry emergency and drain a ton down them. So I removed it and left it just a straight 1.5 inch pipe coming up. Pump set at 60% it was noisy. I then turned it up to 70 percent and it got quiet...occasionally loud but would "catch itself" and get quiet again. Two days later its louder than ever. The pipes are the 1.5 drain that then jumps up to 2 inch pipe for the length of run into sump.. I feel like my long pipes are giving me an issue.. anyone have any input? I know a straight open pipe isn't ideal but like I said when making it a durso the water rose so high it went down emergencys... a LOT. Idk what to do from here I guess..

If you make one of your overflow pipes a full siphon line, then the rest will act like normal weirs and cut the suction/catchup sound.

Doing this on a standpipe is a big weird, as you need the siphon line below the water level in order to maintain full siphon. Like this:

But the real trick is finding the sweet spot so the overflow sound is not too loud (i.e. the water level is high enough to not make now when the water flow over the primary weird).

I just finished my coffee, so I hope that makes sense...

Thank You for your input. I'm familiar with plumbing to some degree as I've had few tanks before, but eith two pipes I cant do the above mentioned method. I've seen people do the two pipes -1 full siphon-1 emergency with a trickle..but I don't have any valves on any plumbing so idk how I would achieve this.. I figured a bigger pipe for the run would prevent this. I also am not reducing through the bulkhead..on durso website they say anything 1.5 and above gains no benefit from reducing..so I didn't. What I also really don't understand is how come I cant do a co conventional durso? As stated, when I pur the top part on to make it a durso the water rises substantially to where emergency is draining excessive water and then that pipe is loud. If I make it the straight stand pipe then the emergency stays dry and the pipe is loud. I even tried putting a tube in pipe to let it get air and it made water level rise just like the durso top. So I'm really confused as to why I cannot add a durso top to this to run durso like I have for years. Maybe pipe is too far in water in sump causing it to need excessive suction thus drawing excessive air?

You are essentially still running open channels. In order to quieten the system, you will have to put valves on the primary drains. Primary should be the 1'; emergency the 1 1/2'. If you are going to put a U on the primary, the upper radius of the U must still be below the lip of the emergency.

Why use the smaller for the drains? Those tee together underneath to a 2 inch for length of run. I guess I'm just not understanding why I wouldn't use the larger of two to be the drain.

If the larger one is drain and I add the U and its top most part is below the emergency drain, wouldn't it try to act as full siphon as air hole would get clogged? I may be over thinking this just due to size... all my other tanks had one drain so I tuned my pump to the durso. Haven't dealt with system or pipes this large before.

So I turned my pump down to 55% and it got relatively quiet. I was deff over pumping my drains. But now I'm wondering do I leave them like this or switch it to a durso?

Ah, that was not clear from your initial post. If the drains are tied together that way then probably your best bet is to have them as stand pipes at the same height and just adjust the pump to the point where the noise is acceptable.
