SLOAN VALVE COMPANY 5301188 A-156-A Flushometer Regal Diaphragm toilet accessory

Regal Diaphragm Replacement Part

The Sloan 5301188 A-156-A is a Regal flushometer diaphragm designed for commercial toilet maintenance. It serves as a direct replacement component for existing Regal flushometer assemblies. Facilities managers and plumbing professionals use this part to restore proper flushing function. The product is sold individually as a new accessory.

Sustained Commercial Operation

This diaphragm is built to handle repeated actuation cycles in high-traffic restroom environments. It maintains consistent sealing performance across extended daily use without degradation from short-burst testing. The Regal design supports reliable operation through continuous demand periods. No specific cycle rating or pressure data is provided by the manufacturer.

Upgrade From Worn Diaphragms

This part replaces deteriorated or leaking diaphragms inside compatible Regal flushometer bodies. The jump is worth it when an existing unit shows incomplete flushes, continuous running water or visible diaphragm wear. It does not replace the entire flushometer valve body or handle assembly. Buyers needing a different flushometer model or a complete valve replacement cannot use this diaphragm alone.
