Need plumbing help

[roscozman]

Ray - I had the exact same problem as you. Let me tell you I have a Dart pump and the two 1" drains is plenty for this pump. I do not even have it dialed down. From the looks of your ball valves above the mag 18, you look to have each at 50% already.

You can cut the PVC just above the 90degree elbow and use spaflex tubing. I even have the glue you can use for free (spaflex uses a different kind of glue vs. PVC). Take a look at our sump area here:

I also had sump burping noise. I eliminated this by placing the end of the flex tube half in the water and half out. I read some where that the air needs to escape out the tube before is comes in contact with the water. The durso is allowing air into your drain pipe. My tank is in the living room and the noise was a problem. The loudest part of my system now is the MP40's.

Again, since I live close to you, you can pick up the glue tonight and I can show you what I did to eliminate the noise. You can also hear it for yourself.
