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.
What happens when a sprinkler solenoid goes bad?
Water leaks: High pressure from a broken solenoid can put a lot of stress on your sprinkler system and burst small or large leaks throughout it. Low water pressure: Low water pressure can be just as much of a problem.
