QRead the Q&A………………………..: We live in a condo community with a homeowners association. It is a second-floor condo. Last Thanksgiving, our downstairs neighbor noticed a drip when we used the master bath shower. I had a plumber come out twice, and he determined the leak is where the shower drain for the master comes into the main drain (we stopped using the shower at that point). The repairs have to be done from underneath (that junction is below the floor line).
