Arrowhead Brass Plumbing PK1390 Vacuum Breaker 3/4 in

Product Description

The ARROWHEAD BRASS PLUMBING PK1390 is a chrome replacement self-draining vacuum breaker designed for use with Arrowhead 485 and 486 BFP frost-free wall hydrants. It provides backflow prevention at the hose connection point, protecting potable water supplies from contamination caused by back-siphonage. The unit features a fine thread inlet and a 3/4 inch male hose thread outlet. It is a direct-replacement component intended for licensed plumbers and qualified service technicians performing field repairs or maintenance on frost-free wall hydrant assemblies.

This vacuum breaker is suited for residential and light commercial applications where frost-free wall hydrants are installed on exterior walls. It is used when the original vacuum breaker on an Arrowhead 485 or 486 BFP hydrant has worn, failed, or is no longer sealing correctly. The self-draining design allows the vacuum breaker to evacuate residual water after the hydrant is shut off, reducing freeze risk in cold climates. Sold in packages of 12, this part is a practical stocking item for plumbing service contractors.

Installation Notes

Installation should be performed by a licensed plumber. Shut off the water supply to the hydrant and relieve any residual pressure before removing the existing vacuum breaker. Inspect the hydrant inlet threads for damage or debris before threading on the replacement unit. Local plumbing codes, including applicable IPC requirements for backflow prevention, should be consulted prior to service.
