Shower drain clogged

[Porchhound]

PO of this 1986 C34 removed shower sump pump because the shower was never used. I have a slow leak somewhere in the head system so I need the drain while I find/fix it. Anyone know where this drain terminates, or where the old sump pump was located?
Thanks in advance.

on my 1986 C34, the shower pump was located behind the cabinet holding the toilet paper.

Porch : The shower pump originally was located under the head sink back directly under the toilet paper box.

I believe that the shower originally drained in to a fitting on the Head intake thru hull.

That drain setup really makes winterizing the head a snap!!  You just close the thru hull, flip the head lever to WET bowl, and turn ON the show sump pump while pouring anti freeze into the shower drain!! Shut OFF the shower pump when you see the anti freeze entering the head bowl. That takes care of both winterizing the head and shower drain - at the same time!!!
