Educate me on tuning the noise from my drain

From what i understand you have to mess with the gate valve all the time to keep the flow consistant and prevent it from making noise. The durso is self adjusting and does not require working with a gate valve at all.

Again, just what I understand as Ive read it here. Correct me if I am wrong.

Now granted I can still hear the drain water rushing down the plumbing but can play with flow to tune, the sucking and gurgling is now gone.

What exactly do we have here?

I find that my Herbie only requires adjusting if flow changes drastically.

Most the time, i need to adjust mine if i get algae buildup on my drain teeth, which slows down the flow into the overflow. The herbie then drains the water too fast, and you end up with a slurping sound.

That said, the algae and my overflow teeth is the real issue and would be moot if i fixed it.

So I was able to use the base of my Dorso overflow tube and just pulled the top off. Grabbed a 1.25" street 90, T, cap and short length of pipe. 1/4" od tubing and a tube of DAP silicon although I did not end up needing it as my not was perfect size. Drilled hole in cap, added tubing and valve leftover from RODI and push all parts together (no glue) put back in overflow and silence.

Uh, no.

I'm using a 2 drain set up that I call the 'Todd Overflow' (irks Bean and a few others).
It's basically a herbie style- but differs in that my drains are draining a True coast to coast 72" lond overflow built into my 180.
The drains are using 2 holes drilled in the back upper wall- 1.5" ID bulkheads.

The 2 drains works much the same, I adjust the siphon line with a valve, and forget it. Quiet, VERY quiet, and works like as champ. the second drain is for any slight extra, and/or clogged siphon.
The air vent line on the second line bends back in my overflow- so if and when the water gets up near the top, it turns the second line into a com;plete siphon- quickly emptying the overflow- unobstructed- no valve on that second line.

*** To The OP-

If you're not going to go with 2 drains;

- put the end of the air vent line back in the overflow, so when the water gets up that high, it turns it into a complete siphon!
