Running out of manifold space in Valve Box
I have three working zones at the moment and a manifold that has outlets for four (4) Valves. I have three (3) working valves (zones) at the moment and one spare outlet from manifold capped off that can accomodate 1 more zone. The problem is that I need to add possibly four (4) more zones in the near future and there is no more space in the valve box for manifold expansion. My electrical timer wires are also pulled to this valve box and the unused wiring is taped off at the current time. How do I go about expanding my system to accomodate these new zones for piping, wiring, valves with my current situation with manifold outlet shortage? Any quick help would really be appreciated. Thanks
