Looking for some help identifying this item that is installed behind my toilet. It's buried behind a panel, forcing me to slide my smart phone through a crack to get this photo. Thus the blur and no ability to see the writing / print on the top of the device.
Yes, that should be the check valve for your blank tank sani-flush system. Per manufacture they should be installed above the toilet. Problems with this system can sometimes be contributed with this valve being installed backwards.
