A broken head resulting in what is called a geyser. Lost water, lost money.
Geysers are pretty in parks but not something you want to see in your yard after you start up your lawn sprinkler system. I see these many early mornings while off to work around 5am and most are still asleep. Spring is here and the time to get your lawn sprinkler system tuned up is now so that your system will be ready when you need it most.
Remember that a broken sprinkler head can waste hundreds of gallons of water in a short period of time even if the pressure does not cause the water to shoot out of the ground like a geyser. For expert service contact Haynes Landscape and Sprinkler Repair.
