One sprinkler zone could be malfunctioning for several reasons, although the most obvious one — a closed valve — is often the culprit. Check to see if the main system valve is closed. It’s easy to forget to turn this back on after repairs. Other causes for failed sprinkler zones are electrical issues within the valve, timer, wiring or solenoid. A common reason is a bad connection that needs to be re-soldered.

Figure out why your sprinkler has low water pressure and determine if you need to make any repairs. There could be an issue with the valve, a leak or the sprinkler heads may need cleaning. If the water pressure is low in your house as well (check your water pressure regulator), the problem may be with the municipal water supply.

Several problems can prevent sprinkler heads from popping up. For example, here are a few possible culprits: 

• The valve is partially closed.
• There’s dirt, sand or debris between the sprinkler’s cap and riser. 
• There's low water pressure.
• There are leaks in the water line.
