BCAB #382 - Combustible Traps and Fixture Tailpieces, Sentence 22.214.171.124.(2)
September 5, 1979
Re: Combustible Traps and Fixture Tailpieces, Sentence 126.96.36.199.(2)
With reference to your letter of July 6, 1979, and further to Appeal Nos. 30 and 39. We do not regard these decisions as conflicting with Sentence 188.8.131.52.(2) of the Building Code.
In Appeal No. 30 we stated that the fixture drain was defined as the pipe connecting the trap of the fixture to another part of the drain system.
For the purposes of Sentence 184.108.40.206.(2) we would therefore regard the restriction as applying to the fixture drain, not however, to the tailpiece or trap, unless these were located within, or passed through, a vertical fire separation.
Your letter refers to sketch 4, where as the above answer indicates, a transition to noncombustible should be made before the fixture drain enters the separation.
