When they say the Y is the restriction, they mean the section of the Y's through the pump itself.
How do you make "the pipe through the T3 B I G G E R". As you and everyone should agree water cannot be compressed therefore the "pipe through the T3" will always remain the same would it not without physically altering the actual pump itself?
