If it was as simple as adding more plug valves, we would never have designed the other two, more complex, systems featured in this thread.

We had to change our design also. The rules do not limit the number of purge valves. The GCD failed to set a quantity and they do not state opening only one purge valve. They have shifted the responsibility to the inspectors. It is kind of a mute point for us this year because our competition is over. The GDC did not answer our question till two days before we had to compete.
