When to Call a Professional
If multiple zones have low pressure or you suspect a main line break, it's best to consult a professional. Signs include water pooling even when the system is off.
FAQs
Why is one sprinkler head not popping up?
Usually debris or low pressure. If you press it down and it feels gritty or sticks, it’s clogged or worn out.
Why does my system lose pressure across all zones?
That’s often a hidden leak or partially closed backflow valve. Check near the main shutoff for wet soil or mineral crust.
Can I just cap a broken sprinkler head?
You can temporarily (use a threaded cap), but it messes with system balance — other heads may overspray.
