Hydrotek HB8-R0125 Sensor Flush Valve 0.125 Gpf Urinal

Product Description

The HYDROTEK HB8-R0125 is a battery-powered sensor flush valve designed for commercial urinals, delivering a 0.125 GPF (1/8 gallon per flush) touchless flush cycle. This unit replaces existing flush valves from Sloan, Toto, and Zurn, making it a direct retrofit option for facilities looking to upgrade aging hardware without full fixture replacement. The sensor-activated mechanism eliminates manual contact, reducing cross-contamination risk in high-traffic restrooms. Installation and service are handled by licensed plumbers familiar with commercial flush valve systems. The HB8-R0125 is built around serviceability, with accessible components suited to routine maintenance cycles in demanding public restroom environments.

This flush valve is intended for commercial urinal applications in high-use public facilities such as airports, stadiums, office buildings, schools, and healthcare restrooms. Its ultra-low 0.125 GPF flush rate supports water conservation goals and may assist facilities in meeting low-consumption plumbing requirements. The retrofit design allows it to drop into existing rough-in configurations originally fitted with Sloan, Toto, or Zurn flush valves, reducing labor time during changeover.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines.

Verify that the rough-in dimensions and spud connection size match the HB8-R0125 before completing the installation. Battery replacement and sensor adjustment should follow the manufacturer service documentation.
