Head Loss from Return Manifold

[skyrne_isk]

Any idea for whether or not it is worth spending the $100ish bucks on a three-way ball valve to avoid head loss that would be involved with using a tee union? I am sure a pair of standard ball valves and a tee could accomplish what this would do but not sure if it would also add unwanted head pressure as well.

Pricey, but think it is an elegant way to temporarily divert flow from the return for water changes.

Thoughts?

What makes you think this diverter valve will result in a lower head pressure than a combination of two standard ball valves and a T?

IMO Its a cool device, definitely more elegant and space saving but way more $, and not necessarily appreciably better.

Spacey

What I understand is the pattern of the holes in the ball on this valve means that it will prevent any flow into the "arm" portion of the tee, unlike a standard tee union on many of manifolds you see on RC. My limited understanding of hydrodynamics would make me think there would be some resistance or turbulence as the return water fills the arm on the tee, this valve would not have that attribute.

I would have to think someone has tested a pump with and without a teed manifold on.....

In the end, it may be all but an afterthought - is that what I am hearing you say?
