Help - Bubbles in Drain Line

[Rbacchiega]

look online for build threads about a "reverse" durso down into the sump area...that should help...or break the water with a filter sock.

I'd say filter sock the bugger or use a pvc 'T' at the end where it goes into the sump. Have the hose cpme ito the sump at an angle and have the branch of the T out of the water and have the run of the T submerged in the sump. This should help the bubbles separate and let the drain asperate the air pockets. Understand what I mean? If not I can try drawing it up.

For zero bubbles there is a full siphon overflow but they are really hard to keep runnning and running smoothly.

what i did is i made it so about half a inch of the drain line is above water so the air bubbles escape right away, then the bottom half inch is in the water to make sure its still quiet, that reduced my bubbles by 80 percent.

That's the same idea as the 'T', except the T stops the water rushing into the surface from dragging more bubbles down.
