The easiest way to test for a bad flapper is to drop some dye tablets into the tank and then check to see if the dye moves into the bowl.
Can you put a new toilet flange over an old one? A standard toilet flange should fit snugly into the outflow pipe and sit level with the subfloor. Installing a new one without first removing the old one will make it impossible to form a seal and keep the toilet bowl bolted securely in place.

Reasons to Caulk Around a Toilet
Moisture Prevention: Without caulk around the toilet base, external water can seep under the toilet, leading to floor and subfloor damage over time. This is especially important in bathrooms with wooden floors, as prolonged exposure to moisture can lead to rot and structural issues.
One reason for a toilet leak from the base might be a loose connection where the tank meets the toilet. Check the connecting bolts. If they seem loose or you can see water gathering in that area, use the screwdriver to tighten them. Approach the bolts from inside the tank and screw downward to create the best seal.

Cracked or Broken Flange: Years of wear and tear or excessive pressure can lead to cracks or breaks in the flange, causing leaks.
Toilet flanges are usually 3 or 4 inches in diameter, depending on the size of the drainpipe. A flange should fit with the pipe either by fitting comfortably inside of it or sliding over it. The pipe length should be adjusted depending on the floor finishing's thickness.
