I'm putting in a shower P trap that will be buried under a concrete slab. The lines and P trap are ABS, but the shower drain base I want to use is PVC. Based on advice from this forum, I'm avoiding using transition cement and will likely use a banded coupling to connect them. However, one other thought occurred to me and I'm curious what forum members think of this: Use PVC cement to weld a 2" threaded, male PVC coupling to the shower base; use ABS cement to weld a 2" threaded female ABS fitting to the ABS P trap; wrap the threads with teflon tape and screw the PVC and ABS fittings together. Any reactions?
