My ears are killing me ....

Finally got around to setting up my 75g. Filled it with RO this weekend and started circulating.

And man oh man is the drain <b>loud</b>. Not sucking topside, but a significant amount of bubbling in the sump. Once I get a heater going, it might make for a good jacuzzi!

The current drain setup looks like the pic on this thread. I am using the AGA MegaFlow kits that look <b>a lot</b> like Durso's.

So before my wife sets me and the tank out on the curb, any and all ideas are welcome!

Ive been tinkering with my latest build as well... similar issue. My GF isn't too happy about the waterfall and jacuzzi being put into the kitchen.... I was surprised that 600pgh through 1'PVC is so noisy...

what ive found is that you want to minimize the air being sucked into the tube, then give it a place to go once it gets to the bottom. top side I put a T on the intake tube water goes in on the side and the T is attached to the tube. the top is capped with a small 1/4in hole bore into it. (think there is a name for these... not sure what).... this prevents some air from getting pulled in, but prevents air bubble blockage.

Bottom side I installed the same thing as the pic in the thread, but with some mods. the tube going into the T bottom side is 1in PVC. This gets expanded to 1.5in on the other two sides of the T. I then elongated the top piece on the T so that it is almost touching the bottom of the tank its under. I also elongated the bottom of the T so that it is about 2in off the bottom of the sump... this overall seems to most efficiently allow water to go to the bottom and air to the top. still not silent, but its not too bad either...
hope that helps... let me know if you would like me to draw a couple of pics to clarify...
Cheers,
Eric

Sound like a Durso. I had a lot of noise with 1, 1 inch pipe but with 2 I don't have very much noise. I didn't need dursos.

Eric;

Thanks for the 1x1.5x1.5 T tip. It's quieter than the 1x1x1 T I had in there.
Like you said, it's not silent, but it is much quieter.

Glad it helped!.. if only I could get my girlfriend to understand the complexity of these engineering problems... and why we need many of them in the kitchen...
