Installation Requirements

This model is designed for a 10" rough-in and requires standard floor flange installation. Due to the inclusion of a pressure-assisted flush system, proper securing of the tank-to-bowl connection and alignment with the water supply is critical. Installation by a licensed plumber is strongly recommended to ensure code compliance and prevent seal failure or performance issues.

Application Suitability

Intended for use in high-demand residential bathrooms and light commercial facilities where clog resistance and flush power are critical. This unit is well-suited for replacement projects involving 10" rough-in configurations that require accessible-height seating and low-maintenance performance.
