Borosilicate glass pipe and fittings may be used for acid waste lines within the building only, not below grade.
9. Vent Flashing: Coordinate with the General Contract for material required and Prime Contractor responsibility.
10. Solder: Shall be lead free, 95/5 solders.
11. Water and Fire Protection Piping: Mechanical fittings for pipe sizes 3” diameter or greater may be used in accessible locations, but shall not be used in inaccessible locations, above finished ceilings or light fixtures. Piping for fire protection systems shall conform to NFPA 13 and as may be modified by the Department and/or local codes.
1004.4 REFERENCE CODES. All codes and standards applicable to design, installation and/or material requirements shall be the latest date of issue. Basic references are:
