Hello fellow RVers. Im a complete newbie to the RV ownership/life. With that said, I bought a 2018 cougar 367fls 5th wheel and I was wondering what the white Valterra waste dumb valve is for located behind the water inlet closet. I have only the Keystone RV Company owner's manual which isn't detailed at all. So basically a limited amount of learning can be taken from this manual. Any help would be much appreciated.
