Help with noise

[scottw]

Ok on my frag tanks, I have one with 2 x 1" drains and 1 is 1 x 2" drain from the side of the overflow, WOW is it noisy as hell!


How can I do a durso from the side and not the bottom and is it possible?

here it is before I took it downstairs



see how its on the end.

Maybe elbow it up then do a standard Durso?
Or maybe go with a "T" with one leg pointing up, and play with a couple elbows. Is the depth of water in the overflow critical to you? Maybe gate valve the drain to the sump to slow down the draining enough to keep air from entering.

ps You look tons like my bro. I had to do a double take.

I agree with Marshal, try the elbow, then durso up from that.

Where is the noise coming from? Is it from falling into the overflow?

The noise is coming from the drain, from the tank. Basically its almost like a surge, it will get full then surge into the tank, it doesnt do it all of the time, but enough to hear it upstairs, bad thing is I wouldnt care but Claudia's room is just above, so thats a no go!

This is what she told me after her nap on Sat... "daddy I hear noise"! so this has to stop..

ok so elbow up then get a T, close off the top of the T and put another 90 on the end of the T correct?

So it will look like this,

Yup, that's it. try to go up a size with the elbow or the tee. If the bulkhead is 1" go up to 1.5" and complete the durso in 1.5". You want the water level about mid point of the tee. For the top, I took a piece of pipe and a cap, slide em together and drill a 3/8" hole. You can turn the cap on the pipe to control the size of the hole, thus the air intake. Works really well.

you could do that or put the 90 on the inside of the tank and put the "T" and the cap and the rest of it on the out side. just have to make the cap past the water level. let me try to figure out how to draw and post what im saying.

I could be wrong, but I think in that last pic it would work like a surge.
