When the sprinkler zones do not turn on at all, it is generally a problem with the electrical signals running from the controller to the valve solenoids. More rarely, it is caused by a faulty valve that needs to be rebuilt or replaced.

Why won’t my sprinkler system turn on manually?
Here are some common reasons why your sprinkler system won’t turn on: Lawn sprinkler control timer isn’t working correctly. Clogged or dirty sprinkler heads. Broken sprinkler heads.
How do you fix a sprinkler that won’t turn?
How to Do It
- Disassemble the sprinkler head.
- Take off the filter at the bottom of the head.
- Rinse the filter in a bucket filled with clean water to wash out debris.
- If this doesn’t work you’ll need to have the sprinkler head replaced.
- If it does work, make sure the head is properly adjusted when you re-install it.
How do you know if a sprinkler solenoid is bad?
Signs that Your Sprinkler Valve Solenoid is Bad
- Never-ending water: The valve solenoid may get stuck open, allowing all or a trickle of water through at all times.
- 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.
What causes a sprinkler head to not rotate?
The most common reason for a sprinkler to stop rotating is the accumulation of debris in the filter. When in operation, water turns a small turbine in the base of the sprinkler, which drives a series of gears that cause the head to rotate. The Hunter gear drive mechanism is sealed from dirt and debris.
Where is the sprinkler solenoid located?
Often the valves are located inside one or more in-ground valve boxes. The tops of these boxes will be at ground level, and these, too, are usually fairly easy to spot and access. The valve box, or sometimes the valves themselves, are sometimes buried underground.
How long do sprinkler solenoids last?
“But, if it’s a good quality valve, it should last 12-15 years out in the field.”
