Not to get stuck on semantics, but doesn't adding a return line to the surge tank turn it into a purge tank? My purge tank is connected to a separate surge tank whose sole purpose is to catch any overflow. The purge tank has a return line back to the wp inlet. Also, the purge tank has a 25# pressure cap while the surge tank is vented to the atmosphere. Mark S. (my brain hurts now)
