How many ohms should a sprinkler solenoid have?
20 – 60 ohms
For irrigation applications, a solenoid is considered to be good if its resistance is between 20 – 60 ohms. It is best to compare resistance measurements to that of a new solenoid.
How do you test an irrigation solenoid?
Valve Test Procedure:
- Turn off the water supply to the irrigation system using an isolation valve.
- Disconnect the solenoid wires from the controller.
- Using and multimeter test the number of ohms through the solenoid. 20-60 ohms – Good.
- If solenoid tests Good, then the solenoid is OK.
Is there a positive and negative on a sprinkler valve?
Most irrigation solenoids operate on AC voltage. DC voltage is polarized, meaning that there is a positive(+) and a negative(-), sometimes referred to as ground. Note: The meter must be connected properly to prevent meter damage, the RED lead is(+), and the BLACK lead is(-).
How do I know if I have a bad sprinkler solenoid?
Signs You Have a Problem
- The Water Won’t Shut Off. If you have this problem, it’s very likely the solenoid.
- Low or Uneven Water Pressure. The solenoid controls the water pressure.
- Water Leaks. There are many points in a sprinkler system that can leak.
- Current Testing.
- Valve Inspection.
- Parts Replacement.

Are irrigation solenoids AC or DC?
Electric solenoid valves are powered by 24 volts AC (VAC) from the irrigation controller. Whenever the controller turns a valve on, it sends 24 VAC to the solenoid. The solenoid is the electronic portion of the valve.
What is an irrigation solenoid?
A water irrigation solenoid valve is an electrically controlled valve to regulate the flow of water. By applying a voltage over the coil, the valve opens and the liquid can flow through. Solenoid valves are also called electromagnetic valve, water valve, electric valve or electro valve.
