Do you have an Orvis retail store location near you? I broke my Orivs rod a few weeks ago and called the store and asked what they needed from me. They said just bring it in.
I took the rod in the original tube. Did not need to show any paperwork or proof of purchase. I am the original owner but they didn't need proof. The store shipped entire rod to the factory and it is being repaired and shipped back to my door. The whole process does take 3-5 weeks from what they quote so you'll be out of a rod for a while but it is easy.
If you don't have an Orvis retail location nearby, here's what my warranty information says from the booklet that came with my rod:
"All Orvis rods carry a lifetime guarantee against breakage due to defects and material. Orvis 25-year Guarantee rods take this guarantee a step further. We will repair your broken rod for 25 full yard, no matter how you broke it. First, call the number below and get a repair number. Then package your broken rod in its tube, place is securely in a heavy outer cardboard shipping container, and send the entire rod to us, no matter which piece is broken. Enclose your name, shipping address, and repair number inside the package. We will return your rod to you, as good as new, usually in three to five weeks. Send to Orvis, Attn: Rod Repair, Historic Route 7A, Manchester, VT 05254.

Good luck.
