Recall 18V050 affects 123 2015-2016 Pierce emergency vehicles for corroding water-pump pressure relief valves. Repair is free at any franchised Pierce dealer.
Pierce is recalling 123 2015-2016 Saber, Velocity, Arrow Xt, Commercial, Enforcer, and Quantum emergency vehicles because corrosion can cause the rings securing Hale pressure relief valves to fail. When the valve opens, water pressure for firefighting drops, which can hinder firefighting efforts and increase the risk of injury; Pierce dealers will complete the repair free of charge.

What's wrong?
The affected 2015-2016 Pierce emergency vehicles use Hale pressure relief valves in the water pump used for firefighting. The valve helps control pump pressure so water flow stays within the intended range during operation. A retaining ring holds that valve assembly in place.
On vehicles with Hale QG, P, or PG series relief valves, the retaining ring was made from the wrong grade of material. After exposure to water, the ring can corrode. If the ring fails, the pressure relief valve opens and the pump loses water pressure available for firefighting.
Routine service can reveal corrosion on the retaining ring before it fails. Leakage at the relief valve assembly is also a warning sign that the part is starting to fail.

What's the safety risk?
Reduced water pressure can hinder firefighting efforts and increase the risk of injury. Corrosion on the retaining ring during routine service, or leakage at the relief valve assembly, is a warning sign to have the apparatus inspected and repaired promptly. Schedule the recall repair soon and tell the service desk about any leakage. Repair is free at any franchised Pierce dealer.
