SPRINKLER TALK FORUM - You Got Questions, We've Got Answers

Hi, i just spring started my sprinkler system and noticed that one head on my 2nd zone keeps on leaking/weeping even after the system shuts off. i put new sprinkler head, i even changed diaphragm and solenoid of that zone valve and it still leaks. i don't know if i should change the head to Anti- Drain valve sprinkler head will it stop? But my concern is that it was never leaking before so if diaphragm and solenoid is not broken what else could be? and how do i bleed/flush valve? any help or suggestions will be greatly appreciated. thank you. flukmanji
