Hey guys. So this is my situation. Three story home. Bathtub and shower on third floor and below that I noticed brown areas from Im guessing water damage. When I check the basement downpipe it is wet on the outside and I have noticed water damage around there as well. After a bath the pipe in the basement is all wet. The bath tub drains fine as I used a 25ft snake to clean everything out and thought I had fixed that. Its like the water leaks out of the pipe and goes to the lowest area in the ceiling and then also runs down the pipe on the other wall and then goes down the pipe to the basement? The house was built in 94. Any suggestions?
