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

Dave-

This post looks very similar to your post of June 20.

fyi sprinkler pipe threads are all right hand threads

If this post is for real.......50 years is very good service for a
rainbird sprinkler & a galv sprinkler system.

My neighbors system is galv & about 60 years old....at this point any
attempts to repair results in a break near by.

Time for a new system or to at least start replacing parts towards
that goal
