Black tank back up....

A few times a year we see this problem, so simplest for minor plugs is to push it down with a stick, or down around the bends with a stiff hose, my favorite ( still yicky) for that is a length of 3/4 BX armored conduit.
We have unplugged all but the dried out ones with our phelps honeywagon adapting the suction hose down to 1" spa hose, sucking up the plug. Good luck!

OMG!!! :E

I added an outer valve after the two tank valves. When I dump, the black goes first, then I close the outer valve and open the gray, this flows with some force into the back tank, close the grey, open the outer valve and dump the black again, repeat until the tanks are empty, then close the black valve and either flush multiple times or fill a bucket and dump it in a couple times, then empty again. Also you want to have a clear extender so you can be sure you are running clean when you are done. Biggest issue is too much TP and not enough water. When we get ready to use the head, we make sure we have at least a couple buckets (3-5) gallons of water in the tank. Do not hook up and leave the valves open! You need to make sure the tank fills and is liquid. I rarely use any chemicals, although on occasions I will use a bottle or two of one of the orange based solutions as opposed to one of the harsh chems. I

I had a 2000 Fleetwood Southwind. It had a 45 right under the toilet, I could see it. Once in a while, I'd have to push "stuff" on through it to the tank. And I do use LOTS of water in the black tank.

I've never had a problem with either of my tanks stopping up, but that 45 did cause me a few "oops" moments. There could possibly have been a burr on the pipe a little further down, that I couldn't see, that was actually causing the problem.

At the beginning of each season I dump hot water and dishwashing gel into the toilet. 1/4-1/2 full of water I keep it there and use the toilet until our first dump. Bill.Satellite is correct. We don't dump until the tank if full. Lots of water will keep the solids moving. Always start with some water in the tank.

Fill it full of water and try dump again. Happy Camper is what I use. There are other products too.

If it is the dreaded pyramid, its under the loo, or in the pipe down. Many MHs & 5ers have a 45 deg. offset from the biffy to the tank. It will plug up real quick if too little water, with too much waste is flushed. #1 rule- (for#2) fillthe bowl with water, flush, twice even.

Rid-X will not do anything unless you leave it for 30 days or more with plenty of water. My best suggesting is to get one of the clear sewer outlet connections that allows you to connect a hose which blow a stream of water up the outlet. This will pick away at any blockage and you will be able to see when fluids start flowing properly. Once you have an open drain you can work on the other solids which may have accumulated inside the tank. That's done with lots of water. You should be able to look down the toilet opening to see if there is a pile down there and you can flush from inside as well to get rid of that. Once the major issues are taken care of you can add water and drive. Even if you don't get it all at this point, it will get better and better over time as long as you flush with plenty of water at every flush. I would flush 2 full bowls anytime you are making a solids deposit. Don't dump until the tank it 2/3 - 3/4 full and start all over again.

Not freezing in south Texas...83 degrees today :-)
