I'm redoing a bathroom with separate tub and shower stall that are adjacent to each other atop a slab. I need to adjust the location of the tub drain for the new, wider tub. But what I found when excavating to expose the drain line was just an elbow that turns in the direction of the shower drain. The shower drain appears to have a trap from looking down into the drain, but there's no opening in the concrete surrounding the shower drain to know for sure how or whether the tub drain line is tied to it.
So my questions are whether the original plumbing was done incorrectly (shouldn't there always be a trap at each fixture)? If I do install a p-trap where there was none, and if this new trap and the one for the shower wind up being in series on the way to the vent stack, am I creating a problem? If installing the new trap is a sound idea, it would solve my drain position relocation problem as I could just angle it over toward the centerline of the new tub.
The original plumbing did work all right before... shower drain would get slow when it was fouled with soap scum; tub never had trouble draining. No odor problems from sewer lines (plenty of odors from rot from crappy job someone did installing incompetent shower pan that failed... the whole reason I'm in this mess.)
Thanks for any advice... hope my description makes sense.
