I found this forum when I did a google search hoping to find a solution to my problem. I have been struggling with this plumbing problem for a long time. Whenever I use the shower on the first floor bathroom there is a big leak to the basement in the beginning the problem was the pipe connected to the tub from the basement was loose but a few days ago I ran into a new problem when I disconnected the tub drain from the tub when I tried putting back the tub drain it is no longer a tight fit the drain moves around the tub hole the tub hole is too big and the tub drain is not long enough to reach the pipe below. I took the small elbow and the pipe connected to the tub from the basement to home depot the employee told me there is nothing wrong with the pipes. I think I could fix this myselff if I knew what pieces I need to do the job. I would like to know what piece I need to make the tub drain a tight fit in the tub hole and is there a tub drain length long enough to reach the small elbow connected from the basement?
