The life expectancy of a sprinkler system is the amount of time it will last before it needs to be replaced. It depends on several factors, such as the quality of the installation and maintenance practices. However, most irrigation systems last between 10 and 20 years. Sometimes homeowners or DIY individuals try to save money by performing the sprinkler installation, but they often end up making mistakes that shorten the life of the irrigation equipment. Make sure to hire a professional for the installation to extend the life expectancy of your sprinkler system. Once the unit has been installed, you should also perform regular inspections every few months to confirm if everything is operating adequately. If there are any concerns, immediately turn off the water supply of the irrigation system and call a professional to fix the problem before further damage occurs.
