Roland, Is there a specific section that lists these variables or were you just talking in general? I thought I was thorough in my water system evaluation. I verified through the city engineer that no valves were closed, no pumps were off, no main breaks at time of BFP test, and that the water tower was not lowered for winter conditions. Anything else I should have checked? The kicker is when you get a water flow test from the water department, there is a disclaimer that the readings may be off by +/- 15PSI! Too bad the fire department only requires a 5PSI or 10% cushion, whatever is greater. It is hard to be competitive if we have to design to a 15PSI cushion for this city. Thanks, Dewayne

Performing a single water flow test is only the starting point in determining the available water supply. It gets quite interesting when a secondary pumps kick in such that the residential pressure is higher than the static.
