I'm almost certain that the drain in the tub in my master bath is
leaking (the ceiling in the garage directly below the tun is stained).
Before I knock a hole in the ceiling to check where the leak is I'd like
to try to fix it from within the tub. Does it make sense that the water
could be going around the outside of the drain? Can I just unscrew the
drain, putty around it and reinstall?
