I can tell you from experience, when antifreeze leaks onto a typed Hydraulic
Placard, all of the information disappears, completely.

A main drain test is for comparison to previous main drain tests only. There
should be one done when the system in put in service. Any deviation from that
means a change in available water but not any hydraulic analysis

The underground losses, hose demand and sometimes backflow preventer losses are
taken before the BoR. Consequently you cannot compare the
I’ve asked this question in the past and the answers have been all over the

I tend to think the BOR location needs to be consistent from project to
