Bean animal overflow question

[roggy23]

First pic is my drains, second pic is my pump controller at the lowest setting, 3rd pic shows the inside of the overflow box..
Note that my secondary drain height is 1.75” higher than my main drain inside overflow box… why is it that when I increase my pump speed the drain flows more and I can’t ever adjust it with the gate valve to make it quiet again? My tank is 180 gallon 6x2x2. Why can’t I add more flow and it remain quiet?

How much flow are you generating with that pump? It's going to be guesswork/trial-and-error without knowing that.

Measure the amount of water flowing through the drain(s) and time how long it takes to fill a container of a known volume....do the math to calculate GPH.

Are your drains 1" diameter PVC?

Is this a new system? Is it possible there's a clog?

1” drains, not a new system. I just wanna be able to up the speed and maintain a quiet drain but can only manage this at the lowest settings … which I think is about 450gph

I just built my overflow and and I had to add a couple of inches to the primary 1" drain and secondary drain to let the overflow back chamber fill up with water. I also have 90° elbows to create the siphon. I let the emergency drain located in the middle start to drain overflow box, then I tweaked my gate valve to allow the water level to be even with the top of my secondary drain. Hope this helps. It was trial and error, but once tweaked totally silent and tons of flow.

I don’t know if I have the room in my overflow to create siphon pipes like you.. the opening sticks out too much

Crap my emergency drain is not in the middle

The inside diameter of that primary drain standpipe looks suspiciously small for 1”, when comparing it to the adjacent secondary drain…

What sort of fitting do you have on the end of the primary drain standpipe? It appears to be a substantial restriction!

—furthermore, 1” sch.40 PVC pipe will struggle to exceed 1,300GPH on a typical aquarium pump… what Simplicity pump are you using?

These elbows are actually intended to be for noise reduction, not starting a siphon! — the standpipe acts like a resonator in some installs, so elbows are added (with drilled air vent hole) to submerge the standpipe inlet during normal operation!

The siphon is started simply by having the water line above the top rim of the primary drain standpipe, then it is controlled via gate so it doesn’t start and stop!

Emergency drain can go anywhere, the whole overflow box changes in water line equally; you don’t magically have a higher water line in the middle!

The emergency does not need to be in the middle. Open top pipes tend to be noisy in general and an open top siphon can create a vortex that draws in air. This creates noise and can severely and limit the maximum flow rate.

What can I do to make it right?

I know but by not having it in the middle I do t think I have the room for Durso type pipes

I don't think its a bean animal design since his is three drain pipes one is emergency. Can you raise the secondary drain? If after you check your flow , and need it at that volume, to keep the secondary from being used? Also a lot covered by others especially about the open tops. Is the noise from the box, or sump? If the sump put the drains under water. The open drains should be double 90s with one having a small hole drilled. The emergency

above the water in the sump to alert you in case of blockages

I thought of raising my secondary… it’s not that bad in my sump noise wise but I think I’m getting too much flow in my secondary and I don’t like the fact that I’m on the lowest settings in my return pump … I want more flow into main tank and not have more noise down below

As suggested check your turnover GPH rate. And use the double 90 approach with the siphon break hole in your secondary . Its hard to see in the diagram but it is there

The opening for secondary is a 1.5” can I make the double 90s 1” to create more room inside overflow box?

You don’t necessarily even need these (double elbow fittings on the top of standpipe), and if you do, it would only be on the secondary drain! (The primary drain [aka Siphon channel] should be fully submerged during typical operation, thus silent!)

— Refer back to my prior post; it looks a lot like the inside diameter of your primary drain standpipe is much smaller than the ID of the secondary drain standpipe… can we revisit that?

— again, which model of simplicity pump are you using here? This will tell us if you’ve got too much pump for either the return or drain side of your plumbing!

I would open up the that red gate valve wide open. Then increase pump flow until it starts to flow into the secondary drain. Using the gate valve to make fine tuning adjustments.

Make sure nothing is restricting flow in the main drain line. Could have a stick or small snail stuck in one of the elbows and it's slowing down the main drain's flow rate. Also make sure the red pipe below the gate valve is not touching anything that could be blocking the flow. I've seen people put sponges down there and not realize it was causing an airlock in the line.

I never saw any previous post you made

Missed it sorry did not want to be redundant

All the drains
are 1 inch. The pump is a simplicity DC 1000.
