thanks for the reply.

is there something i can do to the durso to lower the noise coming from it? I have tried enlarging the hole drilled on the top, tried aspirating the drain w/ some airline tubing, tried removing the durso cap completely, and i still get a ton of noise from the thing.

Right now the flow is very low through the sump, so i dont think it is an issue of too many GPH trying to go through a 1" pipe, and i am at a loss as to what to do.

Hmmm, when I had it the configuration that rendered the least noise was with a homemade filter sock rubberbanded to the end of the drain (in the sump) with the durso open about 1/8".

Questions:

1. Are you using a fliter sock?
2. Which cap are you using on the durso, the one with the hole in the top, or the side?
3. Where's the water level in the drain section of the sump in relation to the drain pipe (is the drain pipe submerged?)
4. Can you pinpoint where the noise is coming from exactly? (I found that most of the water rushing noise I could swear I could hear right thru the piping itself)

Hope this helps Jon.

Hey Bristol,

Thanks for the reply.

1. No filter sock right now - Not sure how it will reduce noise, but i will put one back on and see how it goes
2. The one with the hole in the side
3. The drain is submerged
4. Almost all of the noise seems to come from the drain itself, (the elbow in the tank), but seems to travel the length of the pipe.

You'd be suprised what a filter sock can do. If the pipe is submerged, likely the air entering the sump is contributing to the noise.

The cap with the hole in the side should be open only slightly to reduce the amount of air being sucked down the pipe (which I think is the main problem). You should be able to look at the water going into the elbow & the surface should be flat (if that makes any sense). If there is a vortex, water is going in too fast.

You can change the angle of the elbow slightly, then adjust the durso cap slightly.

ill give it a try when i get home. thanks again bris.
