1 RBC306.2 Scope. The Plumbing Code shall apply to the erection, installation, alteration, repair, relocation, replacement, addition to or use of plumbing systems within the Jurisdiction. The Regional Building Department yields jurisdiction over to the local purveyors for matters and inspections relating to water and sewer services at a point 30inches beyond the exterior walls of the structure, or the water meter, as well as interceptor and separator requirements. In the event no purveyor exists Regional Building Department will assume jurisdictional responsibilities as set out in this code Additions, alterations, repairs and replacement of plumbing systems shall comply with the provisions for new systems. REBUTAL, the newly proposed wording is not necessary, it will have a negative impact on the code. Yielding jurisdiction to local purveyors does not mean that minimum code will be enforced. Independent purveyors may have standards that do not meet minimum code. RBC Repairs and Alterations. RBC In existing buildings or premises in which plumbing installations are to be altered, repaired or renovated; deviations from the provisions of the Plumbing Code are permitted, provided such deviations are found to be necessary and are first approved by the Building Official. RBC All openings into a drainage or vent system, excepting those openings to which plumbing fixtures are properly connected or which constitute vent terminals, shall be permanently plugged or capped in an approved manner, using the appropriate materials required by the Plumbing Code. REBUTAL, this amendment is covered RBC and RBC Existing Construction. No provision of the Plumbing Code shall be deemed to require a change in any portion of a plumbing or drainage system or any other work regulated by the Plumbing Code in or on an existing building or lot when such work was installed and is maintained in accordance with the law in effect prior to the effective date of the Plumbing Code, except when any such plumbing or drainage system or other work regulated by the Plumbing Code is determined by the Building Official to be in fact dangerous, unsafe, unsanitary or a nuisance and menace to life, health or property. REBUTAL, this amendment is covered in RBC RBC Conflicts between codes. When the requirements of the Plumbing Code conflict with the requirements of other codes in matters pertaining to plumbing, the Plumbing Code shall prevail REBUTAL, amendment not necessary, this was applicable when the Uniform Plumbing Code was in affect, and is covered in RBC306.3 Code adopted by reference.
