getting loud gurgle out of your overflow!

For zero gurgling all I know of is the Herbie style but to be safe, they require two holes for drains.

how will i get the elbow to connect?

simple you want to slow down the waterflow to the sump a little this is what you do, put a ball or gate valve at the bottom of your stand pipe have it below the water line and then adjust it just until it stops gurgling. worked for me!

That's not the best idea unless you have a backup drain otherwise one day your drain will plug and you'll come home to an empty sump and wet floor.

okay well pretty much
what i have is a overflow to a T the pipe goes up to a cap with a air hole then down to a 90 degree into a straight pipe to a ball valve then to another 90 to my sump with a micron bag over

Not sure of your bulkhead size but they're easy enough to find (I bought some 1" fr Rona)

This will greatly increase the airflow and mitigate a lot of the gurgling.
try it and see.

free in the air as in out the top by the over flow? like out the cap?
