Probably not considered real plumbing by real plumbers, but I thought you might have knowledge in this area anyway.

For automated garden sprinkler system:

1) Are plastic sprinkler valves reliable?

2) For either brass valves or plastic valves, are the battery operated timers and solenoid on sprinkler valves reliable? Should I be concerned with issue of valve getting stuck in open or closed position?

If you hook up sprinkler valves to the a high pressure water line from the city, meaning over 80 pounds most likely 125 pounds, most plastic valves can't take that kind of abuse/pressure. In those cases metal is better.

Battery operated valves are a "joke". Primed to fail. You want a 24 volt valves with a plugged in timer (battery backup for memory only).

You can count on metal or plastic, or even a combo valve (Body Metal and Valve Plastic). If you adjust the pressure to the valves and regulate the pressure to match the number of sprinkler heads, it should be find. --47.156.xx.xx

Yes it is in the hills and pressure is over 130 but I have separate pressure reducing valves for interior and garden areas. Current valves are all brass and I have the garden pressure set higher at 95. Interior is set at 75.

Do you think that 95 is too high for plastic valves??

I was considering plastic because I thought it would be very convenient to use them with battery and avoid wiring to a central timer location plugged into wall.

I have never used timer and I was not aware battery was such a poor choice but I will avoid battery controlled valves.

Keep the plastic valves from getting direct sun light, this will double their lifetime.

When used those battery valves, they die and the programing gets lost. You have to check on them often. --47.156.xx.xx
