Two Hunter ASV-101 valves, with brass gate valve upstream of the valves, and a Rain Bird
filter / pressure regular downstream of the drip valve. The pipe used is schedule 80. Any PVC
that is installed above ground needs to have UV protection. Schedule 80 pipe will hold up
much longer than schedule 40 PVC (white pipe).
