I have a 2018 Forest River Forester and had incurred what I thought was a clogged outside sink on two occasions this 2020 December.
I was frustrated as I had to impose on my daughter to have a place to lay my head. Remedies were non existent until I read the arguments concerning the problem on the forum.
The argument embraced the stupidity of whether or not the outside sink drained into gray water or into black water. With both barrels loaded and an RV full of water in said sink I srtout to test the hypothesis. Sure enough i connected the drain line to the black sewer tank, yanked the valve open and VOILA! The sink drained immediately.
The tanks are not drained regularly on the Forest River Forester model 2861DS Class C RV motor coach expect the following:
1. Failure to drain the gray water tank will result in back up into the shower pan.
2. Failure to drain the black tank will result in back up in the outdoor sink.
I have a sub issue to #1 which is the valve to the gray tank is accompanied by a valve with a black handle which must also be opened when draining the gray tank. Which tank it drains is beyond my understanding.
