Durso drain noise reduction

The durso is acting as the gate basically. Instead of restricting the flow down by gating it with a valve, you are letting air into the down pipe thus breaking the full siphon and slowing it down. If you do both, I imagine the water will cover the durso and it will just be a funny looking downpipe as the valve itself will probably be doing most of the work slowing things down.

Cheers to that. [emoji482] We've all been there. Just gotta be quick on the draw with the towels and hope the wife doesn't ask why you've suddenly starting running all around the house.
Anyway, don't forget to consider your ATO - since it will start adding more water to the system whenever the return pump section's level drops even a little bit. So your display tank would need to accommodate the volume in your return pump section between normal water height and whenever the pumps run dry + the maximum amount your ATO will pump in before it either times out or runs out of water. Lastly, Murphy always wins, so assume this will happen while you're on vacation for a week. So how long are you ok with letting your system run in that failed state?
So true...I spent many many hours trying to quiet my durso in the sump. I almost went crazy. I know as reefkeepers we're trying to replicate the ocean, but mine actually sounded like breakers on the beach! I have a box full of PVC pieces, fittings, valves, air tubes, etc that were all useless. The only thing that worked, kind of, was putting a valve on my return pump to cut the flow. But then I had very low flow. The problem is my 1"drain was too small to run at only partial siphon.
So I was faced with 3 options: operate with low flow, drill bigger holes in my tank for bigger drains, or convert to Herbie drains.
I converted to Herbie. Best decision I've made on my tank so far. It's silent! I mean, I can't hear it at all!

+1 My Red Sea Reefer essentially has a Herbie from the factory. Dead silent! Seriously, no noise from the drain whatsoever when it's tuned properly. The only sound I get now is a slight trickle in the next sump compartment as the water falls through the filter socks, but raising the level in the sump makes that inaudible with the stand doors closed. Anyways, so much love for the Herbie vs my old Durso junkbox on my old tank (no offense to Mr. Durso
, I'm sure it was a poor implementation)

haha, happy to help! The herbie/beanimal really is next-level awesome compared to a standalone durso.
Nice job with the drilling, btw. Just one thing I want to ask because I've had some annoying experience with bulkheads that loosened over time and were a pain in the butt to tighten - how hard would it be to get a hand or adjustable pliers on those bulkheads if you need to tighten them up down the road a bit? It looks like you've got enough room to slip the pliers between the tank and the wall, but hard to say for sure from the pic

Believe it or not my 2 brain cells clicked and thought about that. I have just enough room to play with the plumbing... and I will test. But what I have found out with the schedule 80 bulkheads is that they need a 1/8-1/4 turn with channel locks.... I learned this on the first water test with the original holes (and yes I cleaned properly and new bulkheads)...... WAF is at an all time high!!!

woohoo! Looks like you've got enough WAF headroom to dump a bunch of money into livestock pretty soon

Congratulations, you really worked hard to problem solve since your first post! Anyway, I see you are using these same flaired lock-line end pieces. I have been mentioning to people that by keeping mine 1/2 in and 1/2 out of the water, it prevents my system from forming a siphon when the power goes out or the pump goes into feeding mode. Just a tip that has worked for me. Best wishes.
