[Shop-talk] removing broken PVC threads

[Ron Horwitz]

Underground irrigation system has a riser that snapped off.  The main plumbing in the ground is a 1/2" PVC tee with female threads.  A PVC pipe with male threads fit in.  The riser broke clean at the top of the tee fitting.  What is the best way to get the riser threads out of the tee?  Nothing above to grip into.  I guess I could drill it out but am afraid of hurting the tee threads.  Is there some trick I don't know?  

Thanks!
