I have my very nice set of custom manifolds made by Lee Brooks at Earth Lee. 1-1/4" body and inlet, two 1" outlets, and 5 3/4" outlets. 1-1/4" PEX will run into one, then the branches will run out of the outlets, and then back into an identical manifold which returns the loop back to the 1-1/4" PEX. Is there any reason I can't install the headers hanging from my basement ceiling with the outlets pointing either horizontally or down? Each branch will have shut off ball valves on both the supply and return manifold.
