Grey water tanks
I have a 2017 chaparral 336 tsik with 2 grey water tanks, I usually don't dump my tanks till they are near full. This is my 3rd chaparral and I usually get one full and the other almost nothing. My question is are these tanks linked or can they be? With the wife and I both taking showers daily one fills up in about 3 days while the other and the black tank have almost nothing. Seems like a waste of a tank if they aren't linked.
