I have a Challenger 37fh (with the 1 1/2 baths) (2 black tanks and 2 grey tanks). The sink in the rear bath drains into the black tank rather than the grey water tank. This causes the black tank to fill quicker and when boon-docking limits the time til black tank needs dumped. To minimize the effects we just do not use that sink when boondocking.

Has anyone redirected this sink drain to the grey water tank? If so, how did this modification work?

I am thinking of adding a y-valve to direct this water to the grey tank or just permanently changing the drain line to the grey water tank.
