My other job is the US Post office and we just had a new building built. On the units on the roof the come out to a p trap then drain on the roof and the site Forman says this is legit since it goes across the roof into the roof drain into a pipe (14 inch). It's this legit and how to find out what an approved drain.

Thanks

There is no inspection city or otherwise since it is federal property. Freezes are rare here in Houston. Thank everyone just trying to understand the "rules"
