Abstract: A dual air vent allows air or gas to be vented from a wet pipe fire protection sprinkler system, but inhibits water from spilling out. A conventional first air vent valve is operative to vent air or gas as a pipe is filled with water, but not vent the water. However, it may discharge a small amount of water when the pipe fills and substantially all air or gas has been vented. The output of the first air vent valve is not released into the protected premises, but rather is routed to a reservoir having a second air vent. Air or gas is vented through the second air vent, but any water discharged by the first air vent valve is retained in the reservoir. The reservoir is connected to the pipe by a one-way valve which allows air flow in either direction, and allows water flow from the reservoir to the pipe, but blocks water flow from the pipe to the reservoir. When the pipe is again drained, water retained in the reservoir is allowed to flow into the pipe, where it is also drained.
