To try to understand what is happening, you have 2 black colored tanks under the trl . One is for the toilet only and the other is for the sinks. Depending on the trl you have you may also have a white tank which is your fresh water tank. The tank for your sinks (gray water) will have smaller drain line than your toilet (black water) tank. It sounds like you have a cracked or completely broken line where the drain line from in the trl goes into the tank because a full grey water tank usually will back up into shower or tub.
