(a) Each operator shall inspect each service regulator when it is installed, at the time of periodic meter change, and at the time a service which has been inactive for a period of two years or more is reactivated to service.
(b) An operator may elect to inspect service regulators at intervals not to exceed 20 years in lieu of inspection at the time of periodic meter change.
(c) Service regulators serving multiple meter installations need not be inspected at the time of each individual meter change, however, each associated regulator shall be inspected at least once each 20 years.
(d) The inspection of the service regulator shall include the following tests:
(1) An outlet pressure test shall be taken under minimum load conditions. Minimum load condition, for purposes of this paragraph, shall mean no load or pilot load only. The pressure limits of this test shall be as established by this Part.
(2) The operational pressure test shall be taken on the outlet side of the regulator with one or more appliances in operation. The acceptable limits of pressure shall be as established by this Part.
(e) Each operator shall inspect each service regulator associated vent whenever the service regulator is inspected. This inspection shall include a test for the presence of gas, proper location of vent terminus, proper size, and proper installation of a weather-insect resistant fitting and verification by an inside the building inspection that the vent line piping is continuous and is properly connected to the regulator. Immediate remedial action shall be taken if any of these items do not pass inspection.
