View Full Version : Checking Controller/Valves

How do you go about checking a controller and the wiring at the valve to make sure that the controller is sending the signal to the valve to come on or shut off and that the valve is getting the signal? Can this be done with common tools?

Thanks in advance.

It's called a volt meter.
Set it to read AC voltage and attach it to the wires going to the valve. It should read around 24 volts AC.
In a pinch, you can connect a known good solenoid for and listen for a clicking or buzzing sound.

This same volt meter can be used to check if the solenoid is open or shorted using the OHMS scale

This kinda falls within the same subject, but i need to ask a question? I have a rainbird system and i was wondering how i could manually pop-up my sprinkler heads so i can change them, without the water?

The only way to pop up the sprinkler heads is to hook up an air compressor to the system. You're better off using your finger nails or needle-nose pliers.

Rainbird rotors will have slots to stick in a key to pull them up. For mist heads I always use a small screwdriver.
