32BHS - Access to water pump?

I'm trying to locate where the water pum is in my Spree 32BHS. ONLY when connected to the City water (and values in proper positions) I noticed the floor carpet next to the "night stand" (just below mirrored closet on left side, in master bedroom, was wet! But if I fill the fresh water tank and run with water pump there is no leak!

So looking for guidance on what might be the issue and how to gain access to water pump or where plumbing lines feed in and route.

Thoughts? Suggestions?

Regards
