I just wonder who can answer the question in my scenario?

I can .... The scenario will almost never occur due to downstream leaks, checked heads or not.

Do I get a prize?

Or how about this ....

Determine total rate of downstream leaks as it relates to pressure, of course factoring in pressure losses in the downstream piping. Then determine the total rate of flow past the diaphragm, again factoring in pressure losses, and relate total contributed pressure and flow from the supply side to the downstream piping. Then determine if supply side leak rate is faster or slower than downstream leaks, and what the pressure relations are with respect to flow & time.
