## Discrepancy

WHEN PUMP WAS INSTALLED, IT WAS DISCOVERED THAT THE THREADS ON THE IN AND OUT PORTS WERE STRAIGHT THREAD.  THE FITTINGS THAT ARE CALLED OUT IN THE IPC ARE PIPE THREAD, BECAUSE OF THE LIMITED SPACE AT THE PUMP MOUNTED POSITION.  OVERHAUL PUMP WAS CHANGED AND THE WRONG TYPE INSTALLED.
