Valve Manifold in California In CA we need to have the the valves with a back flow preventer and the valves have to be above ground about 8". I want to purchase 2 deluxe valve manifolds with 4 pre-installed valves on each (total of 8 valves). I know how to connect the 2 manifold but I do not know what I need for the ascending and descending parts (the parts that go to the valves and away from the valves). Thanks.
