Jessica,
 there is a black rubber seal that fits around the outside of the black 
drain pipe that is about 3" in diameter. If we have sealed all the seams
 so that water is not getting down below the pan, we then have to look 
at the drain one more time before we pull the shower out to investigate 
below the pan. I will look at other fittings that could replace the 
existing drain with new parts that will create a seal. If that does not 
work the fitting below could be cracked or the glue that holds the 
fittings together may have let go. After that I will pull the shower out
 to investigate.
As for the direct deposit let me know how it will need to be set up and we explore that option.
