Dear Experts,
I have a vague recollection that tees with a 22mm “stem” and two symmetrical 15mm “tops” are discouraged because of pressure drop, or something. Or am I imagining that? I think it was probably a post I read here (I can’t imagine where else!).
This is copper CH pipework, at the end of the main 22mm run where it splits under the hall for the last two rooms. A tee with 22mm in and two symmetrical 15mms out “left and right” is the obvious part to use; the alternative would be a tee with 15mm out “left” and 15mm out “straight on” plus a bend or elbow.
This is the part I mean:
