Ok,found out what it is. There are two black tanks, one valve. The smaller tank in the bathroom has a toggle switch that is labeled vacuam pump. On rv repair guy, hubby and I toggled it and it did make a very loud noise, but, did evacuate the fluid in the tank. But, we all thought, that was for emergency only, when the regular flush handle didnt work. Well, the rv dealer we bought from found the owners manuals and schematics , we finally found out that the vacuam pump has to be on at all times. The noise we heard does turn off after about 20 seconds.(we never left it on that long) The pump pumps out the waste from the smaller tank to the larger tank. (((Shaking my head, so much to learn))) Thanks for your help all.
