Sloan Royal 186 Manual Urinal Flushometer, 0.125 GPF, Polished Chrome, DFB

The Sloan Royal 186 is a manual urinal flushometer built for commercial and industrial restrooms that need strict water control and reliable hardware. Operating at an ultra-low 0.125 gallons per flush (GPF), it targets heavy-traffic facilities looking to lower utility consumption. Its polished chrome exterior conceals high copper, low zinc brass castings engineered for dezincification resistance, providing structural strength in challenging water conditions.

Water management is the primary focus of the design. The unit features a fixed metering bypass with no external volume adjustments, paired with a non-hold-open handle that stops water flow after the cycle completes even if held down. Inside, Sloan integrates Clog-Resistant by Interference Dispersion (CID) technology to maintain flush accuracy and avoid clogs, while the diaphragm, handle packing, and vacuum breaker are molded from chloramine-resistant PERMEX rubber compound.

Installation and maintenance considerations are built directly into the fittings. It includes an adjustable tailpiece to fit various plumbing layouts alongside a 3/4-inch spud coupling, sweat solder adapter, and cover tube for a clean, leak-free connection. Tampering is minimized by a 3/4-inch I.P.S. screwdriver Bak-Chek angle stop equipped with a free-spinning, vandal-resistant stop cap. The metal oscillating handle meets ADA standards to provide accessible operation for all visitors.

Because it is a strictly manual valve, this flushometer does require physical contact to operate, unlike hands-free sensor models. Furthermore, the fixed metering bypass means you cannot adjust the volume externally if your fixture requires a higher flow rate than 0.125 GPF. Installation also requires sweat soldering to the water supply pipe.

Verdict: The Sloan Royal 186 is an excellent choice for facility managers, contractors, and building owners outfitting commercial restrooms for high water conservation. Its durable brass construction, chloramine-resistant parts, and ADA-compliant handle make it a dependable manual flush valve for modern commercial installations.
