NHTSA campaign 18V050000
Hazard
Pierce Manufacturing (Pierce) is recalling certain 2015-2016 Arrow XT, Enforcer, Quantum, Saber, Velocity, and Commercial emergency vehicles equipped with Hale pressure relief valves in the water pumps used for fire fighting. Rings securing the valves may corrode over time after exposure to water, causing the ring to fail and the pressure relief valve to open, reducing the water pressure available for fire fighting.
Consequence
A reduction in water pressure may hinder fire fighting efforts, increasing the risk of injury.
Remedy
Pierce has notified owners, and dealers will install a remedy kit, free of charge. The recall began on February 9, 2018. Owners may contact Pierce customer service at 1-888-974-3723 or Hale Products at 1-800-533-3569. Pierce's number for this recall is 74B287.
