Rainbird's website says that their current solenoid won't fit my older valve...they give no recommendations! I have a Richdel R811 solenoid and the piston falls out while other brands don't. Will any R811 solenoid work in my valve? What do I need to know to complete the Repair? Where can I obtain a replacement? Any Info is appreciated
One zone won't open in a 6 zone system. The voltage across 5 zones is 28 volts each and 15 volts across 1 zone. I opened the "Bad" zone manually. I unscrewed the solenoid, ran current through that zone. The piston didn't move. What should I do next?????...thanks
