RE: system modification hydro test

There was some attempt to rewrite these testing procedures during the 2019 process. Some for wet and some for dry. It didn’t really go anywhere but there definitely was a desire to see it changed based on conversations exactly like this. NFPA 13 is open for Public Inputs so fire away!! From: S
