Abstract
One example of a redundant vent for a water-based fire sprinkler system having a pipe network includes a unitary valve body defining a primary valve chamber and a redundant valve chamber, a primary float valve positioned within the primary valve chamber, and a redundant float valve positioned within the redundant valve chamber. The primary float valve and the primary valve chamber form a primary gas vent. The redundant float valve and the redundant valve chamber form a redundant gas vent. The primary gas vent is coupled to the redundant gas vent. The primary gas vent and the redundant gas vent are each configured to vent gas but not water from the pipe network when the redundant vent is coupled to the pipe network. Various optional features, components and water-based fire sprinkler systems are also disclosed.
