Customer called us out for a follow-up because some heads along the street were sticking up after running, concerned they might get stepped on by pedestrians. We didn’t replace the heads during the first visit but we did replace the nozzles. Replaced 2 sticking 4in heads along the street, warranty replaced the 2 MPs nozzles on the heads. 2 other heads in the back yard were sticking as well but the customer decided not to replace those at this time, otherwise the system is working as intended.
