So, Help me understand the differance between a Pex Manifold thats open on both ends and the closed ended types. I'm not certain I understand the supply and return components of the pex manifold. Can anyone shed some light?
I'm just starting to work with an old friend of mine to bring solar electric and hot water systems, wind turbines, Flex Fuel Boilers, batteries, hydroponic gardening, books, pellet grills and more. Also the parts for DIY installation.
Open ones are expandable and the last one is either a closed version or the opening is capped.
