HAHA- i love that.
If your tee-s are above the water line of the sump and not gushing out water i wouldn't drill holes down there it won't help. You may mean drill new holes in the durso? I think mine ended up being 3/16, but this is for 1 1/2 drains so yours may need to be smaller. Also you said its not a straight shot to the sump, the noise could simply be sloshing in the pipe from direction changes, either insulate the pipe for noise reduction or restrict the flow(to fill the pipe with water). I think it always takes tweaking and changing till you get it right.good luck.
PS- there are definete downsides to restricting flow so consider them, an emergency drain is nice to have if you want to restrict flow to reduce noise.

on the subject of quiet drains to the sump, are you familiar with the 3-channel siphon/durso/herbie system?
the siphon is the primary drain channel. you throttle it down with an adjustable valve so that it does the majority of the draining. as you already know, a siphon is dead silent.
the durso is the secondary drain channel. it handles whatever overflow the siphon isn't handling. as you probably know, high flow dursos are still pretty damned noisy, so you want as little flow as possible going through your durso.
the third channel is a herbie style emergency drain. it only works if the other channels clog up. it starts as a durso but converts to a siphon for ultra fast drain flow if the level gets too high.
the 3 way system is totally dead silent at the topside. if you're sure you've got sump flow noise, it might not be the answer for you.

Thanks for the help Bob. My overflow is pretty quiet. I got things quieted down a little bit. It probably doesnt help that its an open stand and I havent sheeted it yet, hard wood floors, and nothing yet really in the room to absorb the sound. If anyone wants to check out how I set it up, feel free to give me a call Saturday. Anytime from 8 to about 2 should be good for me if you guys got nothing better to do.

Alright, here are some pics.
This is the sump.
Heres what I did inside on the sump to quiet the drains, it kind of worked but I think its still to loud.
Here is the overflow, its pretty quiet.
And here is my terrible plumbing job on the back of the tank. Looks like crap, but doesnt leak.
I am open to suggestions if you think there is a better way to do things. This is my first time setting up something like this and I am pretty much just doing it on the fly.

kinda hard to tell what's happening in that last picture, as i don't know what the function of the pipes are. i'm guessing that the two in the middle with the dursos are for your overflow, and the other 4 are for a closed loop?
for the entry into the sump, that method will work well as long as the volume in the sump doesn't change. if the level gets too high or too low, your outlet will either be submerged or fully exposed to the air. submerged will give you burping, exposed will give you a pouring sound.
maybe if you put the T on the vertical piece, so that the side outlet of the T is open to the air, and then the pipe goes down into the water from there... that way it can vent the air to prevent burping, and if the pipe is long enough to go near the bottom of the sump, you'll never have an exposed watery sound. i thinks someone else might have already mentioned is setup. its worth a try if you don't want to make a piece of perforated pipe for the vertical position.

another idea -- to quiet the dumping of my skimmer into my sump, i have the pipe do a 180 before it dumps into the sandbed area. i did this primarily so that the water flow wouldn't disrupt the sandbed. in doing this, the water slows down and overflows out of the pipe gently like a fountain. its not silent, but its not bad either. to make it silent i guess i could just submerge it. BTW, its vented up above to relieve the air pressure.
another way to make things quieter might be to move up to a larger size pipe. bigger is always better.

That is exactly what I was referring to, though you probably worded it much better
The T would sit sideways with the submerged portion you can extend down further into the water so that you can reduce microbubbles and not get the splashing sound if the water level changes.Similar threads
