I had to replace a bunch of heads this spring due to damage. I replaced 2 Toro popups and 5 Orbit rotors with Rain Birds. The popups are 1800s and the rotors are 3504s.
2 of the heads (1 popup w/ the strip nozzle, and 1 rotor) leak profusely around the riser. The rotor is the last head on a 2head line, and the popup is the only head on that line. The popup doesn't even come up all the way, that's how bad its leaking.
I've unscrewed the cap on each and replaced the guts but left the body. I checked for dirt/stones and flushed the lines. All the other heads are fine.
The only other thing these 2 have in common is these lines are the 2 longest ones, approximately 70' and 75'. The lines from the valves are 3/4" poly
I never had this problem when I used the Orbits and Toros. Any ideas?
