Product Description

The SLOAN 0301129 is a relief valve designed for closet flushometer applications rated at 3.5 and 4.5 gallons per flush (GPF). This valve relieves excess pressure within the flushometer body to maintain consistent flush performance and protect internal components from hydraulic stress. It is a direct-fit replacement part intended for installation by licensed plumbers or qualified maintenance technicians servicing commercial restroom fixtures. Weighing 0.06 pounds, the 0301129 is a compact, lightweight component suited for high-cycle commercial environments where flushometer reliability is critical.

This relief valve is applicable to closet flushometers operating at 3.5 GPF and 4.5 GPF flush volumes, which are common in commercial and institutional restroom installations. Typical install scenarios include replacing a worn or malfunctioning relief valve during a flushometer rebuild or preventive maintenance service on water closet flush valves in offices, schools, hospitals, and other commercial facilities.
