I am working on a dry system where we have to install some drum drips. However
It is recommended, but not a requirement.
We will penetrate back into the building (where possible/practicable) to
prevent freezing.
Many times in a parking garage is not possible, some loading docks, etc.

As the EOR, ensuring your client is well aware of the NFPA 25 requirements for

Roland, I'm not the EOR on this project, just the plebe doing the shop
