An Overview of the RV Waste Tank

The waste water tanks in your RV consist of a black water tank and a gray water tank. And there might be a variety of different ones. This unit here happens to have the black water in the back over here and the gray water tank up in the front, here. The black water tank is going to be mostly for sewage, for toilet. Now, there are some manufacturers that will plumb maybe a sink into that, just because of the proximity of the area. But, in general, the black water tank is just going to be for the toilet. Probably not as large of a tank either. It can be identified by the three inch round pipe coming out of the tank, into our bayonet over here. The gray water tank is going to be shower. Most of the time, kitchen, bath sink will go into that. Now, we may have a couple of those tanks, too. We may have one on this side and one over on the other side, just depending on the layout, the floor plan, how it's engineered. So, the idea of it is as the tank starts to fill up, we have probes on all these, here, and it will arc across and it will give us our reading of one third, two thirds, full, et cetera. We have it on the same thing on, on the inside, over there. And the idea is that we're going to put a hose, and right here we have the typical bayonet style hose. It's just going to go on our bayonet here and we will, can run it around right through the bottom, here. We have on the, on the basement models, we typically can just bring it straight through the bottom here, like that. Another thing to keep in mind, always use protective gloves. You've got all different kinds of pathogens in here and that you don't want to get any of this, you know, on your clothes. So, wear a pair of disposable gloves for protection in this. But we're just going to hook it up to our bayonet out here and dump the black water tanks first. The gray water tank second. Now on this unit, it's really easy to get at. It's out in the open. Trailers generally going to be up underneath, kind of exposed to the outside. Maybe way back in. Some of them will even have two different ones. So identify which is your black tank by the three inch. Your gray water tanks, which is one and a half inch, where they're located and that's the basics of the black water and gray water tank or your wastewater system.
