Washing machine drain 345BH
We recently got a combo washer dryer for our 2016 Cruiser 345BH. I hadnít paid much attention but always thought the washer drain was plumbed into the grey tank. I noticed the black tank filling up way too quickly and looking at the plumbing it looks like they T-ed the washer drain into the black tank vent to drain into the black tank. Is this normal? If so, since you are not supposed to keep the black tank valve open I guess I just need to drain it after every couple loads of laundry.
