Re: Problems with Rainbird 100 DV Valve
When I turned on my spinkler system this year, one of the DV 100 valves would not close. I had replaced all the diaphragms about 7 years ago. The valves are about 15 years old. First, I took apart all the valves and inspected the diaphragms. They were fine. Then I started switching the solenoids around. Not much luck. Finally, I manually turned the solenoids to operate the sprinklers so my yard would not die from lack of water. After doing that, voila, the valves started working. They just needed flushed. Take home message for me is that if your valves won't close, try running them and turning them on/off manually to flush them out. I am going to take the advice of another person and seal the electrical connections so I don't get water into the solenoid by capillary action. These DV 100 valves are amazing; they sure last a long time.
