This model is designed for straightforward floor-mounted installation with a 10" rough-in. A licensed plumber is recommended to ensure proper tank-to-bowl sealing, pressure vessel alignment, and compliance with plumbing code. The pressure-assist unit requires no electrical connection but must be correctly vented for consistent flush operation.

Application Considerations for Trade Professionals

Contractor Use: Ideal for commercial or multi-unit projects where durability, water conservation, and high flush performance are critical. The G0020300 is compliant with major plumbing codes and meets high-volume usage demands with reduced maintenance frequency.

Site Compatibility: Confirm rough-in dimension and clearances before ordering. Proper venting and supply pressure (typically 35–80 psi) are essential for pressure-assist operation.
