All MP's, plus 2 zones of drip. Tiny yard, scary in fact. 1 day, me and my "helper" who ripped himself a new one while in the trenches. Creativity with PVC has reached a new high! You hippies ever try that! Main was already stubbed into backyard by developer in class 3/4". (BOO). Simple and quick manifold, carried drip from front zone for plants, new one is for trees. No point in leaving room for expansion, where are you going to go in that yard? Managed to get my boots in the pic; you're welcome.
