1 zone with low pressure. With the solenoid opening it it has low flow and pressure. If I turn it on by hand it sprays at full pressure. Going over there with a volt meter and new solenoid Monday as I suspect that is the culprit. Any other ideas? Valve is a 1" Richdel 205 S. Are these good valves? They look to be. Thank you. Sorry it has been so long, somehow forgot about this superior forum.
