  1. Wow thanks for that great video I never realized you could check the water meter for small leaks like that I usually just turn off the valve manually and check the emitters until it finally stops leaking which can take a while to see if it's closed completely. I was actually searching this video because I want to know if you can tell when a diaphragm is bad just by holding it in your hand if it sticks in the open or sticks closed position or if it's still pliable like a new one and always snaps back let me know if you need a clarification. TIA

  2. I have a leaking orbit impact sprinkler. When I turn off the main it stops when I turn the main on but the stations are off it leaks.

  3. My sprinklers are showing the same leak yours were toward the beginning of the video, however mine only happens when the zone is activated (either manually by turning the solenoid or electronically via the control box). Could this still be a diaphragm issue? I already swapped out the solenoid and that didn’t fix the problem.

  4. I need ur help again: Zone1 heads pop up/seeps water for few secs, whenever I start any other zone. What do you think?

  5. My setup is well pump, not city. Replaced the diaphram, valve seems to work fine manually & automatically (timer controls). Sadly my low point head still dribbling after zone shuts off (about 5 min worth). Any ideas how to fix my low head drainage issue? Hunter PGP rotary head.
