need help with noisy pipes please

With 2 drains make it a Herbie. I had only one 1.5" bulkhead to work with and as a Durso nothing I did made it quiet. I came up with a Herbie type attachment for it and it is now virtually silent.

Access is really tight in there. Be tough to do any cutting/mods at this point. I tried a few holes in the fuge drain and gave up when it did nothing. At this point have the outputs of each half above and below the sump surface and that seems to have stopped the periodic gurgling. Now i just hear minor splashing but it's still too noisy I think.

For the fuge i might hunt around for a 1" valve and make it herbie. For the water change tank I only have the 1 drain. Poor planning on my part but I assumed it'd be safe since that tank only gets filtered water. Hmmm...

The reef nerd in me just wanted to complement you on that lovely Sched 80 plumbing. You didn't skimp at all.

Yeah, I was admiring that as well. I cheaped out and went with schedule 40, which is thick enough but schedule 80 is like the cadillac of pipe.

But isn't Sched 80 acctually Smaller ID than Sched 40? I have pipes of different sched's and they all have the same OD, but the thicker sidewalls acctually mean less flow

I'm sure it means a lot less flow. But when I 'pop the hood' it makes me happy hehe.

I've reduced flow for now in both tanks so that full siphons can't form. I'm sure I don't need much in either. The water-change tank simply needs to run inline and provide me with 20 gallons to change out weekly that's got the same chemistry as the rest of the tank. The pods in the fuge certainly don't need more than a trickle either I'm guessing.

What I might also do later is use a few inches of flex hose on each outlet into the sump so the water enters more smoothly.

Hey Brett, this is what I did with my skimmer:

It's a beckett, so high flow. Did the trick for me. I had it with just a 90 before but it was noisy and the skimmer instructions said not to submerse the drain, but I don't like salt creep so this is what I did. The valve just allows you to make it quiet. I cut and added a T. You should have room to do that. Just have to guy fine a sched 80 "T" and a grey John Guest fitting, or a red one so that everything matches.

Since it's in the sump, I didn't even glue anything.

Hope this helps.
