I am pulling a 1 inch line from a 2 inch galvinized casing. I pulled a couple of years ago (replaced everything new) and replaced the steel pipe with pvc pipe. I lost prime and the 1 inch pipe will not hold water so I am guessing the check valve is broke or stuck open from rust and build up. I pulled approx. 1o feet and the process just jammed tight, can't go up or down. Also will not turn. Prior to that is was coming along good until i back off the hoist and dropped back and jammed up. Any suggestions or tricks? I am scared the pvc pipe is going to break if I force it too much. Thanks in advance. oh well is approx. 80 feet.
