steam main question

steve_6

I have a new install coming up. My question is the existing mains are tee'd together where the boiler feeds them. The tee is "not" bullheaded, it's turned on end. It's a 3"x 3" x 2" tee and the mains it connects are 2", and 3" and is feed through the bottom with 3". Is there a disadvantage to leaving this as is, or should I separate it? thanks in advance,,, Steve

That should work OK

Personally I prefer a separate header takeoff for each main, but the setup you describe should be fine.

advantages

what are the advantages to separating them? Is it steam velocity, or friction loss through the tee? thanks again!!!

velocity

by slowing it down AT the header, more water would be left behind.
