Current through Register Vol. 24-14, July 15, 2024
0306-00 Plumbing, N.O.C
Applies to contractors engaged in plumbing work not covered by
				another classification (N.O.C.). Work contemplated by this classification
				includes activities such as, but not limited to, rough-in plumbing work as part
				of new or remodel projects, placement of pipe (plastic, copper or galvanized),
				cutting and/or threading pipe, soldering, welding or gluing all types of pipe,
				fittings or valves, installation of fixtures (sinks, showers and tubs,
				faucets), installation of appliances (dishwashers, hot water tanks,
				refrigerators with ice and water dispensers), and other necessary plumbing
				activities in connection with water supplies, water carrying, dispensing, or
				drainage systems. This classification includes incidental side sewer hook ups
				(street to house) when performed by a plumbing contractor subject to this
				classification, and only when it is performed as a part of a plumbing contract
				which includes installation of waste lines and waste carry systems within a
				building; and sewer pipe cleaning including services provided by service
				providers engaged in cleaning or unplugging waste lines.
This classification excludes side sewer hook ups performed as
				part of an excavation contract which are to be reported separately in
				classification 0101, and underground water line or water main construction
				which is to be reported separately in classification 0107.
Special note
:
This
				classification includes the installation of display areas or showrooms which
				provide prospective customers an opportunity to inspect the quality of
				workmanship and products carried by the contractor. Generally, displays or
				showrooms are installed where the contractor stores his materials. It is common
				for contractors subject to this classification to sell plumbing fixtures and
				supplies, but the intent of these areas is not to sell products to walk-in
				customers. Sale of these products by a plumbing contractor is included in
				classification 0306. Classifications 2009, 6309, or similar store
				classifications are not to be assigned to a contractor's business. Employees
				engaged exclusively in showing the display areas or showrooms to customers are
				to be assigned classification 6303 provided the conditions of the standard
				exception general reporting rule have been met.
0306-02 Automatic sprinkler systems or fire extinguishing
				systems: Installation, service or repair within buildings
Applies to contractors engaged in the installation, service or
				repair of automatic sprinkler or fire extinguishing systems within buildings.
				Work contemplated by this classification includes installation of pipe,
				fittings, couplings, valves, hangers, regulators, and alarms in ceilings, walls
				and floors, and cutting and/or threading pipe. These systems are usually
				equipped to release dry chemicals or water automatically when the surrounding
				temperature exceeds a predetermined limit.
This classification excludes contractors engaged in the
				installation, service or repair of outside lawn type and
				agricultural/irrigation sprinkler systems who are to be reported separately in
				classification 0301, and contractors engaged in all types of general plumbing
				installation or repair work who are to be reported separately in classification
				0306-00.
0306-03 Boilers, steam pipes, water pipes, heating ducts:
				Installation of covering insulation
Applies to contractors engaged in the installation of insulated
				covering on boilers, steam pipes, water pipes and heating ducts to help them
				retain heat. A boiler is a type of enclosed storage tank erected within a
				building which heats and circulates extremely hot water or converts hot water
				into steam. Contractors subject to this classification may also install water
				jets inside the tanks.
This classification excludes contractors primarily engaged in
				the erection of boiler tanks who are to be reported separately in
				classification 0306-04, and the removal of asbestos from boilers which is to be
				reported separately in classification 0512.
0306-04 Boilers, N.O.C.: Installation, service or
				repair
Applies to contractors engaged in the installation, service or
				repair of boilers not covered by another classification (N.O.C.), including
				boiler scaling and tank erection within buildings. A boiler is a type of
				enclosed storage tank erected within a building which heats and circulates
				extremely hot water or converts hot water into steam. Work contemplated by this
				classification includes the erection and/or installation of the boiler or tank
				(which is above ground), pipes, tubing, ducts, heating units, valves, headers,
				jets and insulation coverings. Also included is the process of boiler scaling
				which is the removal of scales or residue from the tank or pipes using
				chemicals, steam or mechanical methods.
This classification excludes contractors primarily engaged in
				covering a boiler and pipes with insulation covering who are to be reported
				separately in classification 0306-03, and the erection of exterior tanks which
				is to be reported separately in classification 0508.
0306-05 Pump installation, service or repair,
				N.O.C.
Applies to contractors engaged in the installation, service or
				repair of pumps related to water or waste carrying systems, and which are not
				covered by another classification (N.O.C.). Work contemplated by this
				classification applies to all types of water or sump pumps in connection with
				residential or commercial settings, water wells, and irrigation and drainage
				systems. A pump is a device that siphons or transfers material from one source
				or container to another. Activities include pump installation or repair
				services related to a building's water lines and water carrying systems,
				plumbing fixtures, dispensers, swimming pools and hot tubs, water wells, and
				agricultural or irrigation systems.
This classification excludes the installation of water pumps in
				connection with drilling operations which is to be reported separately in
				classification 0103; the installation or repair of service station pumps which
				is to be reported separately in classification 0603; and contractors engaged in
				all types of general plumbing installation or repair work who are to be
				reported separately in classification 0306-00.
0306-06 Water softening or treatment systems -
				installation of new equipment systems
Applies to establishments engaged in the installation of
				plumbing lines for new water conditioning, purifying or softening systems.
				Establishments providing this type of service are not required to be a
				"licensed plumber" to do the installation; however, it does involve plumbing
				work. The installation involves cutting the water line between the water source
				and the building or home. The line is cut with a hacksaw, reciprocating saw, or
				copper tube cutter, depending on the type of pipe involved. After the line is
				cut, the water source is connected to the intake of the system and the building
				or home is connected to the outlet of the system with supply and return lines.
				The bypass unit will allow the water to remain hard for the outside faucet. A
				small rubber hose is installed under the house into the drain. Occasionally, a
				sump pump is needed. For plastic pipes, glue is used to seal the connections.
				On copper pipes, soldering equipment is used to secure the connections. Water
				softening is a process by which the water passes through a resin tank where
				calcium ions are exchanged for sodium ions, resulting in "soft" water.
				Periodically, the resin is recharged by "back flushing" with a saturated salt
				solution from another tank. Installations of this type include the two tanks,
				pressure regulators, valves, and in new facilities an automatic timer.
Special note
:
This classification
				allows for the service or repair of water softening or treatment systems to be
				reported separately in classification 0607 provided accurate time records are
				maintained which distinguishes new installation contract work from service or
				repair contract work.
0306-07 Hot water heater: Installation, service or
				repair
Applies to contractors engaged exclusively in the installation,
				service or repair of hot water heater units. Work contemplated by this
				classification includes removal of old units and the installation of new or
				replacement units. This includes activities such as disconnecting hot heater
				units, removal of plastic, copper or galvanized water pipes, installing or
				setting up new or replacement units, installing new pipes, cutting and/or
				threading pipe, soldering, welding or gluing all types of pipe, fittings or
				valves, filling and testing the new or replacement units, and wrapping hot
				water heaters with insulation blankets.
This classification excludes contractors engaged in all types
				of general plumbing work, or when the installation, service or repair of a hot
				water heater unit is performed as part of a general plumbing contract which is
				to be reported separately in classification 0306-00.
