You say first trip. New to RVing? Do you know how the dump valve handles operate? (Sorry I can't assume anything, you don't provide much in the way of details.)

How do you know plenty of liquids are in them? Are you just believing your tank level indicators?

Do you have a transparent hose elbow? If you leave your gray valve open and run your sink, is any flow visible?

First, welcome aboard! Glad you're here. Second, what's the year and model of your trailer?

Dan, CD had it right when he said we are lacking info. What did you do when you tried to empty? How many tanks? Your personal info is zilch. How long since your last dump? I could go on and on...

The OP has made two posts on the forum, one back in January where he asked for an explanation about cell phone bands (post #12 here: https://www.keystoneforums.com/forum...546#post372546 )

And now this thread. With the limited information and the lack of response for further clarification, he may follow his pattern of waiting 2 or 3 months before asking an unrelated question in another thread.... Let's hope he provides further explanation and answers to the questions needed to help him fix his problem.....

Time will tell:

If the tanks are full doesn't that mean it's time to sell or trade?

Time to take the rv to your dealer. A fifth wheel trailer friend of ours had to do that after putting too much toilet paper into the black tank. Have you tried to add water to the black tank for dilution and did you add sufficient happy camper treatment to the black tank? Have you tried to back flush the drain line (s)with water? Surprising that even the gray tanks do not drain unless their clogged. Seems unlikely all the tank valves have failed closed but possible and need to be checked by the dealer.

Had that happen to the guest head on our powerboat, we were living, twice. Each time required a sanitation technician to come out to tear the system apart to unplug the system at $1000 per event. In one case, wine bottle corks fell out of a guest's back pocket and were flushed down the vacu-flush toilet. Another flushed a whole roll of toilet paper down the vacu-flush toilet after being on the boat one day.
