Bought the house last fall. Had sprinkler winterized and company blew out lines. This summer, turned on the water and everything would go fine for a few days at a time. Then, sprinklers stopped working sporadically. I did notice that when the controller kicked on and sprinklers did NOT turn on, 1 sprinkler in the in the 3rd zone started collecting water. I tried to manually turn on the sprinklers today by turning the solenoid but didn't work. It did get water dripping through with a hissing sound.
