Black tank not dumping

We are on a trip and just went to dump tanks. Black tank is not dumping but gray tank is. We are at 44%. Any suggestions to get it to dump? We are getting ready to add RV Digest but hoping someone has other suggestion.

Hook hose up to black tank flush and see if you can get some water running through it? If the valve is opening you may have some solid matter in the way...

Any water flow at all?

Is the valve handle working normally or has the stem come free of the valve blade?

Sometimes the handle comes loose. Try to screw it back in.

Could the guage be reading incorrectly?

Im with Schu. If the handle were disconnected you would know as on that model the ends of the dump valve assemblies are exposed. I would maybe get a flashlight and check down the toilet to see if the tank is actually empty and maybe your sender pad is reading incorrectly.

As said by another, make sure the valve is actually open. Close the water supply to the bowl, open the flush gate on the bowl and flash a light into the tank to confirm level. I have had no success with the level indicators installed so I just rely on counting days of use or looking into the tank. If there is a blockage in the tank discharge to the common outlet, buy a cleanout elbow that fits onto your discharge. It is made by Camco I think and is clear plastic. This device has a city water hose connection and gate valve on it. They are also supplied with a backflow preventer. Hook it up, close the gate valve and briefly open the city water line which will send the water back into the black tank. With your drain valve open on the trailer, check that the water is actually going into the tank. Have someone on the inside of the trailer to confirm this by again looking down through the bowl. YOU DON'T WANT TO BACKFILL THE TANK TO OVERFLOW !!! . If the water flows into the tank it will flow out. Connect your dump hose to the device and open all the valves and it should dump.

Perhaps, the tank dumped, you didn't hear it, and your senders are bad. Fill the bowl up, flush the toilet, then open the valve and see if water comes out.

Same thing happened to us

We had the same problem and posted a blog on how we deal with it.

Sensors could be bad... or could they require calibration? I read somewhere that sometimes they need calibration....

I understand your frustration as I also have a problem with the black tank valve not closing all of the way. I have not fixed mine all the way and uutimately take to dealer, however, I have learnt alot in the process. first be sure to use the proper TP. Second after flushing tank add more water with cleaner to preven stuff from sticking and third purchase after marke back flush value and use it periodically. I have found it cleans better then the one on the AS. As to checking inside the tank. I am not sure how to do this with out a camera or taking removing the toilet bowl. I thought the camera were expensive for a one tme use and I have no desire to remove the bowl.

Regarding a camera. Costco has a waterproof flexible camera with light that is used for inspecting sewer pipes etc for $79.00. This is cheaper than a stop at most dealers.

Use it once and it pays for itself. Dave

You wont be able to recalibrate your water systems sensors. If the valve is functioning and the sensor is the actual issue you will need to change the sensor. This is actually fairly easy on your trailer.

Other than the sensor what makes you think the tank has water in it. Sensors are notorious for false readings. Have you shined a light down the toilet while the flush valve is held open?

It is highly unlikely you could get a condition where NO water would flow from the outlet if the valve is opened. It is just not the nature of what we are dealing with to cause zero flow.

Again I ask did any water flow from the valve when you opened it. That will define if the valve itself is working.
