Hi, I have an old Rainbird Sprinkler head on a galvanized pipe. Both the are 50 years old. Cannot determine model number. Sprinkler still works but may have weak springs.
My question is about removing the sprinkler head from the galvanized pipe. Does the rainbird unscrew counter clockwise or clockwise? I've been spraying chainsaw penetrating oil in the copper galvanized joint for days and it won't loosen.
What else can I do to remove that sprinkler without damaging the rainbird or pipe and threads? Is there a better penetrating product?
Thanks, Dave_s
