This is the main sprinkler manifold. I've already added a regulator (The new MP Rotators *have* to run a specific pressure) with a particulate screen and a new shutoff. I have to do a modification to how the water gets routed to the West side of the hill as it's currently fed from the left end of the manifold at regulated pressure. I need unregulated pressure out there.

The 3 larger valves are for the West, East and pool planters respectively. The remaining 6 valves are for the front (2 zones) and rear (4 zones) lawns.
