In the Galley!!! Thanks for that answer. I know when we were on vacation, and the tub was backing up with water, I checked the fill level indicators and they were all empty. So, I'm pretty sure that the sensor has a problem. Are those very hard to change out or clean? I will use it a few more times and see what shows up on the sensors. It looked like there was a "T" between the Black water gate valve and the Gray water gate valve, where they both dump into the big 3" pipe that you dump in. Any idea if there is a check valve that keeps poop from getting pushed into the gray tank if that valve was open? I always dump the Black tank first and then flush out the hose with the Gray, but if a guy forgot that gate open that could be bad if the bad stuff could get pushed into the gray. Thanks, for any clarification you can give me.
Mike
