Grey water
Is the bathroom sink in a class a supposed to be plumbed to the black or grey water tank?

our bathroom sink as well as the shower goes to the black tank. only the kitchen sink goes to grey. i understand the need for more water for a better flush of the grey, but it generally results in a black tank needing dumping while the grey still has only approx one-third tank. kind of a weird configuration i think.
