Delany Products 141-ACQ Diaphragm Repair Kit 4.5 Gpm

Product Description

The DELANY PRODUCTS 141-ACQ is a diaphragm repair kit designed for Delany flushometer valves rated at 4.5 gallons per minute (GPM). The diaphragm assembly is the core pressure-sensing component inside a flush valve — it controls the flush cycle duration and water volume. When a flushometer begins double-flushing, fails to shut off, or delivers inconsistent flush performance, a worn or compromised diaphragm is typically the cause. This kit provides the replacement parts needed to restore proper valve function without full valve replacement. Licensed plumbers and commercial plumbing maintenance technicians handle this repair in institutional and commercial restroom settings.

This repair kit is suited for commercial and institutional restroom applications where Delany flushometer valves are installed — including schools, hospitals, office buildings, and other high-traffic facilities. The 4.5 GPM flow rate corresponds to standard water closet flushometer configurations. Proper diaphragm replacement restores the designed flush volume and prevents water waste caused by faulty valve cycling.

Key Features

• Designed to restore flush performance in Delany flushometer valves at 4.5 GPM
• Addresses common issues including double-flushing, failure to shut off, and inconsistent flush cycles
• Allows valve restoration without full flushometer replacement
• Targeted repair component for high-traffic commercial restroom environments

Compatibility

Designed as an OEM-style diaphragm repair kit for Delany flushometer valves with a 4.5 GPM flow rating.

Installation Notes

Installation should be performed by a licensed plumber following applicable local plumbing codes and IPC guidelines. Shut off the water supply to the flushometer and relieve line pressure before disassembling the valve. Inspect the valve seat and related internal components for wear while the diaphragm is removed. Reassemble per the valve manufacturer sequence and verify flush cycle performance after water supply is restored.
