View Full Version : Y instead of T

on a loop im putting together due to tightness of space i decided to use a Y instead a T before my pump. this shouldnt be an issue should it? Im using 1/2" for the line itself then 1/2" to connect the Y to the pump. I didnt see any problems with this but this is only my second loop.

Just keep in mind, whenever you make water change direction, you increase resistance in the loop. A T would work better, but if you can't fit it, then you have no choice. But again, using a Y inplace of a T impedes the overall flow.

how am i making it change direction?
-----Y to fillport -----\
____________________\_________to pump -----to rad-----
____________________/
-----from blocks------/
my flows stays circular, unless im missing something.

Whenever there is a bend in the loop, thats considered a change of direction. The tighter the bend, the more restriction you get.
It is good however that you are using the straightes part of the Y for the active loop, and I doubt that its increasing your temps by a measureable amount.

I doubt that it would have much of an effect at all. Most likely not measureable, however.

if there was going to be a bend there anyways, theres absolutely no reason not to use a Y.

This would be a better setup as any air would tend to go up the fillport line.

Yeah, I guess it would make it harder to bleed having it the other way, but having it that way would probably have an effect on flow.

That does sound like a good idea, but I can see alot of potential turbulance when half the stream is forced up the fillport line and displaces the still water.

If you're super critical about flow rstriction just stretch your tubing over a 3/4" wye. and you'll have less flow resistance than the equivalent length of a straight piece of the tubing you use.

The effect on flow I'm thinking about is when the water hits the Y and some of it tries to go up the fill line.

There are sites where you can do online flow calculations.
