How do I join together two drain pipes in a wall? I have a drain pipe for a shower which is visible on a kitchen wall after I removed the soffit. I have another drain pipe about two feet away but it is around a corner. The second drain pipe would be invisible (behind wall). The pipe is PVC 1.5 inch.

Your queation's not very clear. Are both pipes PVC? Why do you wish to connect them? One pipe's a shower drain, what's the other one? What exactly are you asking? What fittings to get around the corner or simply how to connect two pipes together?
Back to you, Tom

Please post some pics of your setup and describe exactly what you are trying to achieve. We will take it from there. Thanks.
