I'm a little bit hung up here. I'm going with dual 1" PEX lines, and I'm figuring out how to run the lines into a single fitting. From in/out of the boiler will be 1-1/4" black iron. I need a way to go from 1-1/4" to dual 1". I know I could use a reducing tee, but that seems like it would really reduce flow. Can anyone give me a good option? The best I've come up with so far has been a Y branch, but that seems like it would favor one line more than the other.
