Next, place the flange over the drainpipe and align it with the bolts. Once the flange is aligned, tighten the bolts until they are snug.

Test the new toilet flange.

Once the new toilet flange is installed, you should test it to make sure that it is not leaking. To do this, turn on the water to the toilet and watch for any leaks around the flange. If you see any leaks, tighten the bolts until the leak stops.
