Hard to diagnose for sure from afar, but highly likely that built up "stuff" in black tank has blocked opening.. If it sat for a while other than totally empty and rinsed, that can happen.. Can also happen if you've ben parked in a campsite for a few days.. Black tanks really work better after a nice bouncy drive, maybe with a trayload of ice cubes tossed in on top of chemicals..

That said, first option is to try and get hose with nozzle inside bath and spray into toilet in direction of valve while valve open. Some newer larger trailers have external hose connection for such a sprayer, but they can be a hazard as well..

I know people who have been unsuccessful clearing blockage with hose/water spray who have bent wire coat hangar and used it through open valve to clear blockage as well.. VERY difficult to do that without also getting somewhat dirty and smelly, but it could be a lot of buildup and be necessary...

If it is really leaking from belly pan, then you may well have a cracked pipe or failed valve body, which will be difficult to fix quickly and cleanly from a campsite.. (Sorry..) Ours failed and would no longer seal completely and some models have valve a long way and a 90 degree bend from outlet/cap...

Not sure if you have separate black/gray tanks, but if not, be sure all of the sink/shower drains are plugged securely as well...


In Theory, there's no difference between Theory and Practice, but in Practice, there is usually a difference...

He is going in with a coat hanger (actually a metal hot dog stick we found on our campsite non returnable-ha!) suggested he wear a rain parka, plastic gloves, and offered a facemask with perfume! Thanks for your reply.

The same thing happened to me this weekend. To find out I did not open the dump valve outside. Once I opened it problem solved. This age-thing is creeping up o me

Added a metal coat hanger to the metal hotdog roasting stick and still couldn't find the clog. Eventually the fluids leaked to a low enough level, so it stopped. All the drains were shut, so nothing backed up inside. My husband even climbed a ladder and looked down the vent tube to see if nastiness had tried to escape through there, but it was clear. Thankfully the weather was nice, so the neighbor was able to enjoy the fresh air outside and all the Rally meals provided at a different location. His wife left, but returned when things aired out! If I find out the actual cause and solution, I will let you know.

Sounds similar to a problem I was having with my '66. The toilet paper we were using was NOT septic or rv safe. Once the tank filled enough, toilet paper was clogging the black tank vent, which resulted in very slow tank drainage once the valve was opened. In addition, the toilet "burped" when trying to flush things. Not at all pleasant.

I was able to free things up using a combination of the coat hangar method and flushing the vent from the roof with a stream of water from a hose. Lesson learned!

I would make sure the trailer is level. I was at a rally one time were a couple were complaining about the samething on a small trailer. They had the trailer so out of level nothing would drain. Once someone showed them how to "correctly" level the trailer, the stuff came out just fine.
