What is a solenoid in a sprinkler system?
The solenoid is what controls the water pressure. It receives an electric current from the controller to determine what adjustments need to be made. It uses a plunger to adjust the valve, and there are a few more moving parts in the mix. All of this is what allows an automated sprinkler system to run things for you and provide that great convenience. But when the solenoid is bad, you can get some weird sprinkler problems.

This will give us a close look at everything and help us find the faulty part.
