Tank heater? What tank?

[Indy500]

Is this switch for fresh water tank , or black and gray water tanks? I didn't use this but once last fall and never needed it.

I can’t speak for yours but my tank heater switch turns on heating pads on all 4 of my tanks.

Is there a way to find out what tanks are heated? And thank you for the info.

You can drop the coroplast belly cover and look. That’s what I did.

After owning a couple Rockwoods, they have always came with all the tanks heated, plus the valves. You can also just call Rockwood they will tell you....

There should be heat tape at the sewer valves. At least they use to have it on the 8289WS. But saying that my new unit doesn't have that but it's not a Rockwood. But there is still pads on all holding tanks, fresh, gray and black. A call to Rockwood would verify that.
