Step 6 · Reinstall the Toilet
Remove the temporary rag from the drain pipe. Install the new closet bolts into the slots on the new flange. Place a new wax ring on the flange, pressing it gently to create a slight seal. Carefully lift the toilet, align the holes in its base with the closet bolts, and lower it straight down onto the flange. Press down firmly with your body weight and give a slight twist to compress the wax ring and create a seal. Place the washers and nuts onto the closet bolts and tighten them alternately until snug. Do not overtighten, as this can crack the porcelain base. Reconnect the water supply line, turn the water on, and check for leaks at the base and the supply connection as the tank fills. Flush several times and check again for any signs of water.
