Brian, I may be looking at this too 'simply', but wouldnt your suction pressure be the static pressure at the flow test location plus or minus any pressure gain or loss for any difference between the elevation of the flow test and the fire pump suction?

Since we didn't do the original system and I know nothing about it what is a practical way of determining the pump suction to tell the vendor? Brian Harris, CET BVS Systems Inc.
