Buy G2 Optima Plus® Flushometers

ProDryers is an authorized national distributor with deep inventory and fast shipping on G2 Optima Plus® flushometers for toilets and urinals. G2 is a battery-powered, sensor-activated line designed for high-traffic restrooms that want hands-free reliability, ADA compliance, and consistent water performance. It’s a proven choice for schools, healthcare, airports, offices, and any facility prioritizing hygiene and uptime.

Why Choose G2 Optima Plus®

  • Touch-free infrared sensing for hygiene and user comfort, with a courtesy flush override button on the cover
  • ADA compliant sensor operation with automatic activation after the user leaves the sensing zone
  • Built for tough environments such as high-humidity, high-activity, and low-water-quality settings
  • Fixed metering bypass with no external volume adjustment ensures water conservation is maintained once the correct diaphragm/regulator is installed
  • Serviceable design with widely available repair parts, including the flex-tube diaphragm and a replaceable solenoid operator

How G2 Works

An active infrared sensor detects the user. When the user steps away, the control sends a signal to the solenoid and initiates a flush after the built-in delay. The electronics are battery powered and sealed inside the module; the valve body meters the correct water volume using the specified diaphragm/regulator for your model’s GPF.

Core Models and Common Use Cases

  • G2 8111: Exposed, sensor water closet flushometer (e.g., 1.6 gpf). A go-to for standard commercial toilets
  • G2 8180: Exposed, sensor urinal flushometer (e.g., 1.0 gpf). Reliable option for high-traffic urinals
  • G2 series overview: Available across closet and urinal configurations; bedpan-washer models also exist for healthcare

Note on dual-flush: G2 is typically configured as single-flush. If you need dual-flush logic, use ECOS complete valves or DFSM dual-flush side-mount operators on compatible diaphragm bodies.

Maintenance, Batteries, and Reliability

  • Battery type and signal: G2 uses a field-replaceable battery pack; when approximately 4,000 flushes remain, the LED provides a low-battery signal so you can schedule replacement before downtime
  • 4 AA batteries are installed in the module; replace as shown in the maintenance guide and reseat the gasket to maintain a proper seal
  • Cleaning: Avoid harsh chemicals and abrasives on the cover and chrome. Use mild soap and water only

Pro Tips from the ProDryers Team

  1. Match GPF to the fixture. Pair the correct diaphragm/regulator kit with the bowl or urinal spec; don’t “open the stop” to compensate. Excess flow creates noise and can cause splash or run-on
  2. Place sensors to avoid false triggers. Keep the sensing window clear of mirrors or strong reflections; verify the factory range before adjusting
  3. Plan battery swaps. Use the low-battery LED as your signal to change all units on a line-item schedule. It’s faster and prevents downtime
  4. Choose the right upgrade path. For retrofits, top-mount G2 modules and side-mount operators solve different problems. If you need dual-flush logic or a split-button manual override, a DFSM side-mount may be the better fit

Frequently Asked Questions

Is G2 Optima Plus® ADA compliant and touch-free?
Yes. It’s a sensor-activated system that flushes automatically after use, meeting ADA goals for hands-free operation.

Does G2 work in tough environments?
Yes. It’s designed for high-humidity, high-activity, and low-water-quality settings, and it’s widely used in demanding facilities.

Can I adjust the flush volume on the outside of the valve?
No. G2 uses a fixed metering bypass. Select the correct diaphragm/regulator kit for your required GPF; don’t try to tune by opening the stop.

How do I know when to replace the batteries?
The status LED provides a low-battery alert with thousands of flushes remaining, so you can plan replacement during regular service.

Can I get dual-flush with G2?
G2 is typically single-flush. For dual-flush, use ECOS valves or a DFSM side-mount on compatible diaphragm bodies.
