Have you noticed a soggy patch in your yard? Or maybe your water bill is creeping up for no reason? It could be nothing, or it could be a leaky sprinkler. It’s one of those issues that often starts small but can quickly lead to wasted water, dying grass, and costly repairs. At Spartan Irrigation, we know how frustrating it is to spot signs of a problem without knowing the cause. That’s why we’ve broken down the most common reasons sprinklers leak and how to fix them.

Is It the Sprinkler Head?
One of the most common culprits behind a leaky sprinkler system is a damaged sprinkler head. These can become cracked or broken from lawnmowers, foot traffic, or even harsh weather conditions. If water continues to seep out of a head after the system turns off, the internal seal may be worn out. Replacing the head or its internal components is often a simple and affordable fix.
Are There Loose Connections?
Just like with plumbing, loose or faulty fittings can lead to frustrating leaks. Sprinkler pipes and valves need to be tightly sealed to function properly. If you notice water bubbling up around the base of a sprinkler or along a section of piping, it could point to a connection issue. These leaks might require digging to access and tighten or replace the connector.
Is the Zone Valve the Problem?
When a specific sprinkler zone won’t stop leaking, even when turned off, it’s often the valve to blame. Zone valves control the flow of water throughout your sprinkler system. If one isn’t closing all the way, it may be clogged or damaged. Flushing or replacing the valve can usually solve the issue.
Should I DIY or Call a Pro?
While some minor leaks can be patched up with basic tools and a little know-how, bigger issues—like underground leaks or full system malfunctions—are best left to the pros.
