Dirt-filled valve boxes indicate rodents - rodents chew wires (all the wiring should have been checked at the first sign of trouble)Ok update... I ran a totally seperate line for the power supply to the control unit. I got a new transformer. The outlet was tested everything was good there. Wired in the new transformer and it lasted a whole 1hour... WTF.. I looked in the containers for the valves (4 of them) and they were full of dirt.. 3 gallons worth. Could this be my problem? I may resort to my local sprikler shop, but really don't want to pay that kind of money. Any thoughts...?
My current Orbit timer has a 24vac 300mA transformer. If I need to replace the transformer can I use the transformer from my previous non-Orbit timer? The old transformer is a Class 2 24vac 20VA transformer. I will most likely have to order a replacement transformer due to my local.
