Diehard
In Remembrance
The bottom line, as far as I am concerned, it is poorly written. And if I wasn't retired, I know I could get them to clarify it in writing. I don't remember what they officially called it but we were able to pose questions and they would answer them in writing.DieHard, I do not see it as ambiguous. at all
the code states how a indirect drain is to be installed
and where it is to terminate
a T&P IS an indirect drain
clearly the code is saying the pop off runs to a floor drain and terminates with an airgap
OR
runs outsside
Typically, the water heater pan and pop off are run outside from a unit in the attic
but, can also be done on a unit that is on a outside wall

If it wasn't poorly written, we won't be having this discussion.
