Black Tanks Won’t Flush

I have two black tanks that discharge out one outlet. I have two unmarked black tank connections in the water compartment. Connecting to one, no water flows, when connected to the other, water discharges out the other. I tried a Y connection with no luck. I checked the only one way valve in the shower and it appears to be plumbed correctly. I cannot find another. Any suggestions?? Thanks David

    Add two bags of ice. Drive for awhile, then empty your tanks.

    Could there be another slide valve located somewhere underneath? I had motorhome which had shut-off slide valve which had to be opened before it would come out the
    normal outlet... sort of a safety situation. Just a thought.
