Yup, that bottle in the corner was emptied yesterday evening.  And yes, that’s standing water after this morning’s shower.  Oddly, it wasn’t standing last night after I ran the plumbr down the drain.

Of course, I haven’t ever known my sink to do this while I was taking a shower, either.  So yeah, I think I have a larger plumbing problem.  Perhaps more Liquid Plumbr down ALL my drains?
