I have a Grohe shower system that I will be installing in a couple of weeks. The adapter between the water supply (hot and cold) and the unit itself are straight pipe threads. I'm assuming that Teflon tape will do for sealing these threads but I've seen plumbers use cord and compound on these threads (you rough up the threads and apply the cord and compound. I'm hoping Teflon tape is good enough for this. I know the straight thread to pipe thread can't be sealed with Teflon. Anyway, input is welcome.
