The plastic fitting inside my antisyphon device (FEBCO 765-3/4) froze to the pipe holding the device during the winter and I had to gouge it out with a hammer and chisel, in the process damaging some of the threads in the pipe which has prevented installing a replacement device. I've searched locally and on the internet for a thread chaser but have not found one, but there are apparently taps for this size (plastic fitting measures 1 3/8 OD) available at a very high price. I am wondering if forum participants have any suggestions on how to fix this problem without having to buy a new tap to clean up the threads.
