(c) ABS Plastic, exposed to sunlight, shall be protected by water base synthetic latex paints . Where surface temperatures exceed 165°F, piping shall be protected by means of shielding or some type of light- weight insulation. PVC Plastic, except vent piping through roofs, shall not be installed so as to be subject to direct sunlight after installation. Where surface temperatures exceed 140°F, piping shall be protected by means of shielding or some type of light weight insulation. (d) A variance in application of these materials may be allowed by the administrative authority in a particular case when specifically certified as warranted by a professional engineer.
