Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off the water supply valve at the toilet before beginning any tank service work and flush to drain remaining water from the tank. Avoid overtightening the mounting nut, as this can crack the tank. Verify proper water level adjustment after installation is complete.
