At some point in a system you have to transition from the underground material to the aboveground material. If the UG material is PVC for whatever reason where would you put your transition flange, in the concrete slab?

As of right now, section 6.3.1.1.1 will read: 6.3.1.1.1* Underground pipe shall be permitted to extend into the building through the slab or wall not more than 24 inches. The annex note reads: A.6.3.1.1.1 Extending the underground into a building provides working room to transition to the appropriate above ground piping. Environmental conditions should be considered as outlined in 23.1.6.1.2 That was voted on in the report on comments, 13-79, Log 34. Interesting, to say the least.
