Slip on EJ-5 out 3-1/4” covered + 3-1/4” showing = 6-1/2” of 8” total. 3/4” pipe sawed off in foreground is where trap assembly T-5 was cut out of line for repair approximately a year and a-half ago--probably due to the strain imposed on the trap piping by the broken anchor.(See next picture).

TSU explains that they have had trouble finding a professional welder with equipment that could perform the necessary welds and they do not have the equipment or men in house to accomplish the repair . I would agree that the tunnel is indeed a difficult place to access with electric arc welding equipment. For that reason, although some trap assemblies have been welded to stop leaks caused by strained piping, all trap assemblies should be assembled with screwed piping so that they can be repaired without electric arc welding .
