Basic Plumbing Question

[Johnny Reefer]

No, neither. Not a Y. Not a T.
I wish I could draw it.
I don't know how else to describe it.
Think of an elbow.
Now think of an opening coming out of the side of it.
I guess it could be looked at as a Y. but the single opening wouldn't be on the same plane as the other two, but rather at 90 degrees to them.

Maybe if I describe where I want to use it....
6' tank with two corner, bottom drilled, overflows.
I want to run a length of PVC under the stand from one overflow (#1) over to the other (#2). Overflow #2 will go straight down. Where overflow #2 meets the pipe from overflow #1 is where I need the 3 way elbow because from there I want to run it straight out the back of the stand to the sump, which will be in behind the main tank. The 3-way elbow would facillitate the movement of water in three different directions at one point.....One direction horizontal from the left (#1 overflow); second direction vertical from straight down (#2 overflow); third direction horizontal out the back of the stand. Hope that makes it more clear.

Just wondering if there is such an elbow to make this possible.

Thanx much,
