The Fisher 11355 Spray Valve Repair Kit is designed to service compatible commercial pre-rinse spray valves by replacing worn internal components. It works by renewing key parts such as seals and springs that control water flow, pressure, and shutoff performance during routine operation. Installing the kit allows the valve to operate smoothly and consistently under normal working conditions. Benefits include improved spray control, reduced water waste, and extended usability of existing equipment without the need for full valve replacement. The kit supports regular maintenance practices, helps control repair costs, and offers a practical solution for keeping kitchen cleaning operations running efficiently.
