Employers included in Code 5183 may install, remove, or repair equipment that is used to direct gas or water supplies to a destination. This equipment includes but is not limited to piping and related fixtures, appliances, and accessories. There are no limits on the size of the pipe being repaired or installed.

Shop work associated with plumbing operations is additionally assigned to Code 5183. Code 8227 applies to a permanent yard maintained by a plumbing contractor. Refer to Code 8227 for information that distinguishes between shop and yard operations for classification purposes.

Irrigation and drainage system construction operations conducted in connection with lawn sprinkler installations are classified as Code 6229. Trenching work performed by the same contractor who installs underground pipes for sprinkler systems is assigned to Code 5183 since trenching work is an integral part of the underground sprinkler installation work. Such operations may be performed using either a vibrating plow or a pipe pulling machine, which knives the ground to a depth of 12 to 18 inches and to a width comparable to that of the piping being used. The piping is then automatically inserted into the ground.
