Problem- one station of the sprinklers in the back lawn will not shut off, even when main supply is turned off the heads still leak continuously. The lawn is so soaked and the water bill is creeping up each month. We have changed out the diaphragm and solenoid - Rain Jet (?) model #54000 RJ711 by Lawn Genie 3/4" anti-syphon - any suggestions how to trouble shoot next? And how do you "flush" out the system for dirt and debris?
