How do you split your return line

Can a. T fitting work hose barbed style, if so how would you position it. I would think on it's side would allow water to be heavier flow on the vertical run and slower on the section Horizontal? Then horizontally is it slowed on both because of direction of flow?

Imbarrie just said you dont know what youre talking about, Skene! You gonna take that?

Do you really think a "T" will reduce the flow any real amount versus a "Y". If you care that much be sure that both return lines are the same length. We wouldn't want one side to be slightly more than the other.
100% know that it will. I am not saying don't do it, only that if you have the option then go with the 45.
Think about any kind of flow in an enclosure. A redirection of any kind will reduce flow. A 90 will reduce flow more than a 45 exponentially.
The problem is compounded depending where you place the splitter? You may need more than one 90 degree if you do this in the overflow.
If you can live with the reduction then it is worth it.

I'm just thinking, if you can get a wye to increase flow, why not use it?
The length would matter if you're using the same exact elbows only, but regardless, I would put instead focus on maximizing flow on both outputs, and then put a ball valve on both to equalize flow, or if you wanted 1 side more.

Believe me. If your return pump is worth a dollar the flow through a "Y" will be the same as the flow through a "T". Where do you think the water is going? The losses due to a longer hose is much greater than any flow resistance difference between a "Y" and a "T". If you place the "T" in line and cap one end of the "T", do you really think the flow will change? Granted there will be a slight increase in resistance due to the additional distance the water needs to flow through but a "Y" or a "T" or a bend in the hose is negligible. There will be more losses of flow going through a ball valve. The flow is dependent mainly on the pump & the diameter/length of the return line.

Head loss is greater through a T than a Y. This is a fact. Use the link above to calculate the exact loss if you're concerned. It may not be enough to warrant going crazy, but there is loss.

Also, if you want to get all crazy, you should factor in gravity. If the Y is leaning a certain way, the flow will favor one side.
Depends on your application and how much you really care.

Facts which are not arguable -
Corals and fish are pretty.
I like cookies.
T's and 90's reduce flow.
Russ is not an idiot.
Russ is one of the nicest and most helpful guys on earth.

if the line is pressurized i think you would have the same flow with y or t. if their is no resistance and water is just flowing, the y will give more even flow. it all depends if their is pressure in the line. again just my opinion from working with hydraulics .
