I went to clean out hair from upstairs bathroom. I got a lot out but I think some went down. The water drained fine and my husband said clear water was draining from a black 1 1/2 inch black pipe below onto the patio. The shower did the same thing. I used a zip-it tool and a sink drain 20ft flat drain cleaner. I got more out but it still drains onto patio. Of course they are on their honeymoon so I can't call them. I dont want to use declogger chemicials if it will run on patio close to pool and dog. How is the plumbing done here? Is it an overflow pipe? I am from Ohio and this is weird.
I just put down very hot water and ran both shower and tub and closed off overflow bathtub drain and a large hair clog flew out of the pipe to the patio , but it still drains out to patio .
