I have 2 2nd floor bathrooms that seem to be on the same drain pipes to the basement, something is leaking, and it appears to be when I use the second floor baths, but I also have a 1/2 bath on the first floor directly below the other 2, the toilet for that was plugged a couple of days ago, and I pulled to toilet, found nothing, but still leaks when upstairs water is used, should I snake the 1st floor toilet pipe, and hope for the best. Any help would be great.

I would like to help but I need to know where is the leak? "something is leaking" Location
Toilet? Iam surprised this post got through the cracks Need more info please
