Installation steps

Prep. Shut off the water supply, flush to empty the tank, then disconnect the supply line.
Remove the old toilet. Unbolt from the floor and scrape the old wax ring from the flange.
Set the bowl. Place a new wax ring on the flange, then lower the bowl onto the flange and press down firmly.
Attach the tank. Hand-tighten the tank bolts evenly to the bowl, alternating sides.
