Back flow preventer

I want to change the shower sump in a 1999 330 Fiesta Vee while it is in the water. Is there a back flow preventer in the gray water, thru the hull discharge hose? I don't want to flood the boat. This is my first time on this forum. What is the meaning of "Tags"?

    I would think that your discharge is above the water line (as was mine) and there would not be a check valve or  flow preventer.  -Paul

    It makes sense for it to be above the water line. Thank you.

    Really should not need a check valve, plus they can get crapped up and not work right. 

    I did replace the thru hull with a right angle brass fitting and replaced the junk plastic tubing with better stuff (hose kept leaking). In the process I ran the new tubing with a loop to prevent water from flowing backwards in high seas.  More a CYA since I had it all apart.
