Every residential sprinkler installation is backed by our 1-year warranty against defective materials and workmanship. We also offer extended 3 year manufacturer or 5 year manufacturer warranty options. During the warranty period, Tri Aqua Irrigation must perform the lawn sprinkler start up, periodic inspections and sprinkler winterization for the warranty to remain in effect. We want you to be fully satisfied with Tri Aqua Irrigation and even offer a 100% Customer Satisfaction Guarantee as one of our Customer Loyalty Programs. We will work diligently to make sure you are happy with your new sprinkler system and the service we provide!
