Thank you for the reply. Not sure why I didn’t get a notification someone replied. Was talking to someone who does this for living. He was recommending not to use manifold and use slip on, like Hunter 24V Inline and have them separate (thoughts?).
As for the valve box? What size, there seem to be many or how can I tell what size. I would be using a 2 Line Manifold.
