Question
I have a richdel irrigation system controller (clock/timer) model 508Pri/512/Pri.
The system works manually though if I set the timer to a certain time the sprinkler does not turn on. It only works manually.  Does this mean I need a new irrigation system clock?  The clock is at least 13 years old.  Could it be another problem that can be fixed?  Please advise asap.

Answer
Hey Susan, this particular controller is not worth repairing. Just install a new controller. Try either the Rainbird ESP series controllers, or the Irri-Trol "Rain Dial" series controller. Either one will be easy to program, and last for a long time. Good luck and have a great day.
