2008 ZR porta potti issue.
 

How do you flush out the whole potti system.
My wife the dumb@ss she is needed to make sure that she was safe if she needed "go"...
Im upset with her using the head and all but... Now I have no freaking clue how to empty it..
Anyone that can help??????

Surprized nobody replied yet. That boat probably has a porta potty. If so, the bottom simply detaches and carry it to a toiled and dump it out. Be sure to close the "seat inlet" before doing so. Then rinse accordingly.
If you have a pump out porta potty, they are meant to be sucked out at a marina. Otherwise seperate as above, manually disconnect the hose w/out splashing, and dump in a toilet and rinse. The pump outs are a pain for a trailered boat.
