Code cite 4 painting plastic vent pipe above roof

[David Meiland]

Can anyone tell me if there was/is a code requirement in any of the various codes to paint ABS, PVC, etc., where it's exposed to sunlight as a vent terminal above the roof?

The requirement in the Uniform Plumbing Code is not in the code itself but in Appendix I "Installation Standards". How far back it goes I don't know.

It's in both the 2000 and 2009 as those were the editions that CA adopted.

Installation Standard For

ABS BUILDING DRAIN, WASTE, AND VENT PIPE AND FITTINGS

IAPMO IS 5-2003

2.2.3 Exposed Piping

Piping shall not be exposed to direct

sunlight. Exception: Vent piping through

roof. Plumbing vents through roof, exposed

to sunlight, shall be protected by water base

synthetic latex paints. Adequate support

shall be provided where ABS piping is

exposed to wind, snow, and ice loading.

Installation Standard For

PVC BUILDING DRAIN, WASTE AND VENT PIPE AND FITTINGS

IAPMO IS 9-2003

2.3.3 Exposed Piping

sunlight. Exception: Vent piping through

As a side note in the "Dwelling Requirements of the Uniform Plumbing Code, 1997" they don't list Appendix I.
