RE: Residual PSI at BOR and Main drain test
For comparing to the BOR info, it is not a great idea. If you have a light hazard system where the demand is 100 gpm and you do a full open main drain test where you may be flowing 200-400 gpm (just made up numbers), then your main drain test should have a lower residual than what is at the base of the riser requirement for the system.
