Drain flex pipe...

[Michael Faul]

I'm trying to figure this whole girgling thing out. I cycling and 4 days into it. The first day I had to power back my DC pump to slow the flow so my drain could keep up. It helped somewhat BUT the noise is back today. I may be wrong but my question is......

Would my flexible drain pipe that is curled under the tank like a P trap under a kitchen sink cause the problem?

I have a Maggie Muffler too.

I use a gate valve to control the flow from the overflow to the sump my pump is to small but enough flow. The drain pipe is losing siphon and there is not enough volume of water going in the drain pipe. As you stated you dialed back the return pump. Is there a way to can dial it back up just a tad?

What's your drain setup? How did you plumb?

On mine I put valves on the returns to the sump so I could slow the flow of the main return enough to get rid of the gurgle
The one on the left in my picture is the main drain from the overflow, just the slight closure on that pipe fixed the noise

Here's what my plumbing looks like.

Yes the loop in your return line would cause noise. I had the same problem so I straitened the line and no more noise.

I may have to engineer one out of PVC. That way I can put a gate valve on it and have more control.

No loops in the plumbing. Shorten the tubing or rearrange something.

If it still doing the same thing with the drain plumbing fixed, then you're running too much flow.

2x to 4x the size of your display tank is all you need.

If you have a 65 gallon tank, that's just 130 GPH to 260 GPH.

I hope that helps! :)

That's great info everyone. Much appreciated.
