Tapco 1055637 Closet Urinal Diaphragm

Product Description

The TAPCO 1055637 is a replacement diaphragm designed for use in closet and urinal flush valve assemblies. The diaphragm is a critical internal component that regulates water flow during each flush cycle. When this part fails, flush valves may run continuously, fail to flush completely, or deliver inconsistent water volume. Licensed plumbers and commercial maintenance technicians replace this part as a routine service item to restore proper flush valve function without replacing the entire assembly.

This diaphragm is suited for commercial and institutional plumbing environments where closet and urinal flush valves see high daily cycle counts. Typical applications include restrooms in office buildings, schools, healthcare facilities, and multi-unit residential properties. The part is installed inside the flush valve body and is accessed by removing the valve cover, making it a field-serviceable repair that keeps downtime minimal.

Key Features

• Direct replacement diaphragm restores flush valve performance without full assembly swap
• Compatible with closet and urinal flush valve configurations
• Lightweight construction at approximately 0.008 pounds for easy handling during service
• Designed to address continuous-run and incomplete-flush valve failures

Compatibility

Designed as an OEM-style replacement diaphragm for closet and urinal flush valve assemblies. Refer to your flush valve model documentation or the original part number on the existing diaphragm to confirm fitment before installation.

Installation Notes

Installation should be performed by a licensed plumber or qualified maintenance technician. Shut off the water supply to the flush valve and relieve line pressure before disassembling the valve body. Follow applicable IPC guidelines for flush valve servicing. Inspect the valve seat and surrounding components for wear or debris before seating the new diaphragm to ensure a proper seal.
