Hello. I've got 2 problems to tackle:
- I'm having trouble with a handful of my pop-up (4" I believe) sprinkler heads not popping up. When I pull them up they stay up and spray through the cycle, but then they still have trouble popping up the next time it runs. This is true of various heads on different zones. I've wiped down the shafts and even sprayed 3in1 oil, but they're still sticking. They all seem to go back down fine after the cycle completes (albeit a couple with a long delay).
- Some of the sprinklers are popping up at slight angles, so the spray isn't optimal anymore. Been about 7 years since the system was installed, so I assume the ground has simply settled and moved the underlying piping to this scewed angle. Should I just dig down to the sprinkler base and gently twist the angle back to optimal, or should this be left to a professional?
Thanks in advance for the help.
