Sloan Regal 111 Exposed Manual Water Closet Flushometer
The Sloan Regal 111 is a 1.6 GPF manual flush valve with a top spud connection and polished chrome finish. It uses Para-Flo technology for accurate flush volume and a non-hold-open handle to prevent overuse. A vacuum breaker flush connection aids hygienic operation. This model is best for busy facilities that require predictable water usage and durable, low-maintenance performance. Best for new or retrofitted restrooms with high daily turnover where precise water savings matter. Caution: installation requires standard plumbing connections and careful alignment to valve body for optimal performance.
Sloan Regal 186 Exposed Manual Urinal Flushometer, 1.0 GPF
Featuring 1.0 GPF, the Regal 186 emphasizes water conservation with a non-hold-open handle and no external volume adjustment. It includes a vacuum breaker flush connection for backflow prevention, making it suitable for mid-to-high-traffic public restrooms. Choose this when you need dependable operation with moderate water savings. Best for facilities prioritizing efficiency without complex electronic components. Limitation: 1.0 GPF may be insufficient for very large or oversize urinals in high-use environments without firmware-level adjustments.
Sloan Regal 186 Exposed Manual Urinal Flushometer, 0.5 GPF
The 0.5 GPF variant targets water-savings-first installations with a non-hold-open handle and no external volume adjustment. It includes a vacuum breaker flush connection for backflow prevention. Best for facilities with strict water-use targets or where urinal usage typically stays within lower flush volumes. A potential trade-off is fewer flush volume options compared with higher-GPF models, which may affect performance under peak demand.
American Standard Ultima Manual Urinal Flush Valve
The Ultima 1.0 GPF valve features DynaClean self-cleaning wiper spring technology that helps maintain a clean refill orifice and reduces valve run-on. It is designed for 3/4″ exposed top spud connections and aims to balance reliable performance with maintenance simplicity. Best for facilities seeking automated cleaning-like efficiency within a manual-valve framework. Limitation: depends on consistent cleaning cycles to maintain optimal performance in some environments.
Zurn Aquaflush Exposed Manual Diaphragm Valve
The Zurn Aquaflush valve covers a 3/4″ top spud with 1.0 GPF capability and includes a sweat-solder kit and a polished chrome-plated wall flange. This model is best for installations requiring a straightforward, durable valve with simple field servicing and a chrome finish for long-term appearance. Choose this if you value a compact, easily installed valve with reliable performance. Caution: ensure soldering procedures follow local plumbing codes to avoid leaks over time.
Sloan Regal 110 Exposed Manual Water Closet Flushometer
The 3.5 GPF Regal 110 model uses Para-Flo technology for precise flush volumes and a vacuum breaker flush connection. It’s designed for large-volume flush requirements and high-traffic restrooms, making it a better choice where powerful flushes are needed to clear heavy waste loads. Best for facilities needing robust performance despite higher water use. Limitation: higher flush volume may not align with strong water-conservation goals in some locations.
Zurn Z6000-WS1-YB-YC Manual Flush Valve
The Zurn Z6000 series includes a 1.6 GPF option with a polished chrome-plated cast wall flange and a sweat-solder kit. It’s suited for installations requiring a standard, durable, and serviceable valve with flexible piping options. Best for facilities valuing a versatile valve with straightforward maintenance. Caution: ensure the solder kit compatibility with existing wall materials to avoid leaks.
American Standard Ultima Selectronic Touchless Urinal Flush Valve
This 1.0 GPF valve uses an automatic sensor and a self-cleaning piston to reduce maintenance needs in high-traffic restrooms. The Selectronic model switches to water-saving mode during heavy usage, helping to balance hygiene with efficiency. Best for facilities prioritizing touchless operation and reduced maintenance in busy restrooms. Limitation: relies on battery power for sensor operation, which could require periodic battery changes.
Buying Guide
Key considerations when selecting a commercial urinal flush valve include water efficiency targets, flush volume variety, and maintenance needs. Consider the following questions to match the right valve to your project:
- What is the target daily water budget, and which flush volumes best fit expected usage?
- Is a mechanical (manual) valve acceptable, or is hands-free operation preferred for hygiene?
- What connection type is required (top spud, sweat-solder kit, or other) for compatibility with existing plumbing?
- How important is backflow prevention and a vacuum breaker in your installation?
- Are maintenance intervals and ease of service important for you or your maintenance staff?
- Does finish and appearance (polished chrome, exposed vs concealed) matter for the restroom design?
FAQ
What is the difference between 0.5 GPF and 1.6 GPF flush valves?
0.5 GPF prioritizes water savings for low- to moderate-use restrooms, while 1.6 GPF provides a stronger flush suited to high-traffic environments or larger urinals. Choose based on usage and fixture size.
Why is a vacuum breaker important?
A vacuum breaker prevents backflow, helping to maintain sanitary conditions in commercial restrooms.
When should I consider a touchless valve?
Touchless valves reduce-contact surface and improve hygiene in busy restrooms, beneficial for high-traffic facilities.
Do I need a heat-treated or solder kit for installation?
Some models use sweat-solder kits; verify compatibility with your wall materials and local codes before installation.
Are higher-GPF valves less water-efficient?
Higher-GPF valves use more water per flush. They may be necessary for certain urinal designs, but they reduce overall efficiency if used in low-demand areas.
