Are you sure the sensors are bad? I've had similar problems with both readings. I found many times I needed tap the gauge while holding the appropriate button (fresh water or waste level)... Another thing I did was to pull the sender for the waste tank and found it clean but it doesn't reach the bottom of the tank...I've included a diagram showing the depth my sender goes down in the waste tank so when the tank is less than 4" full it shows empty.
