It varied greatly. Some were only 1-2 inches, some were quite a bit longer. I am somewhat limited by the height of my pressure pot, but can make it protrude more upon request.I meant to ask.
How long will the threaded rods be, and how far will they protrude from the emitter?
I'm no expert, so please forgive me, but I feel like I remember the originals having a longer protrusion....
