By the second week of a rainless August, Smithtown's sandy ground has given up whatever the last storm left, and lawns start showing it first along the hot southern edge. Long Island Sprinklers Repair spends those middays on irrigation — chasing a head that will not pop, a zone that quit, a line that seeps where it should not. Spring is startups and pressure checks; late fall is blowouts before the first freeze can split a pipe. Water put down evenly is the difference between turf that coasts through a dry spell and turf that goes straw-colored by Labor Day. That work runs through Smithtown, Nesconset and the towns beside them.
