Ridiculous Clogged Thetford Toilet

I can’t seem to unclog my toilet. So water is about 4” high above flush flap. The tank was completely drained, at my campsite last weekend...except for this clogged section of water.

I have tried the boiled water method.
The chemical additive to eat tissue.
The plunger.
And I just snaked the line.

The water is still standing.

Any idea of what could be happening?

I am wondering if maybe it’s a vacuum issue with the stink pipe, or something like that. Maybe the snake was not long enough, it’s probably snaked out about 3’ and I can crank it.

Ant suggestions?

This is in a class a 2007 Itasca Sunova 35J

Got kids....Missing any toys?

Missing any combs, hair brushes, toothbrushes etc

If this is a standard gravity dump Thetford Toilet then you have an object lodged in the toilet to tank line which has wads of TP stuck to that object.
Turn water supply off....Glove up...roll your sleeves up and reach down into toilet line as far as you can --retrieve the object

If unable to reach object then you may have to remove toilet so you can reach farther down line
Bail water out using a cup until water level is below floor flange height

Snakes, chemicals, boiling water etc will NOT remove object

Did you snake from the toilet side or the drain side? And did you see the snake come out the other end?

One option is to get a brass hose sprayer (the one you twist and it stays on) and start sending it up the drain side while it's on. Hopefully it will arrive at the problem site and start to dislodge the offending matter. It's a dirty job so make sure you have long rubber gloves and a face shield.

Big, fat hands like mine will not go thru the flush valve hole, if yours same, you may want to consider some type of positive action long grabber? (If Assuming Old Biscuit right?)

If it is below the level of the flange, I have had some luck using one of these type devices

Thanks for the advice!

Such a great community here, I appreciate everyone trying to help out. I’ll keep at it, and try some additional methods as described. I did not try going up the emptying end.

Definitely my hands would not fit through, funny I thought you were referring to an “old biscuit” in another sense..

Thanks

Thanks, I’ll keep at it. I guess I’ll be bailing out some dirty water today.

I did not try the drain end, I guess it’s possible, tank was empty...but maybe it wasn’t and I thought it was. It’s definitely worth a shot, an yeah I have a straight nozzle end, so I’ll give that a try. I guess I’ll need some containment buckets should things loosen up.

Thanks

That a pretty cheap option to try, I guess if the other methods described Fail I may order one of these. I wonder if HF stocks these in store, I have one a couple miles away.

Thanks

lowe's/HD sell rubber expandable drain cleaners in various sizes. your drain line is 3" 4" wide. select the proper size adapter. connect water hose, insert in drain pipe, turn on water and hold on cuz what ever was in there is coming out fast.

If the pipe from your toilet goes straight down and doesn't make a turn you can try "snaking" with your awning pole (if you have a manual awning it has a pole with a hook at the end to grab it and pull it down). That clears a straight pipe well and the hook might bring a toy, etc. back up. If you don't have a manual awning you could still buy the pole. Ours is extendable and takes little storage room.

I went back to work with the auger, 3rd attempt seems to have worked. I appreciate everyone’s support, I guess the best advice is not to give up. Hopefully it will be smooth sailing for the near future. Of course something else needs to give out soon.....

jdmalibu:

Glad to hear the "third auger attempt" worked for you.
Just to follow up, did you find anything "untoward" as the culprit?
Otherwise, I would assume the problem was "pyramidding" in the tank, where the contents gets piled up, solidifies and (as you found out) is a PITA to get rid of.

The only time we had the problem was when we were boondocking and were trying to be "thrifty" with our water supply. But if you're hooked up to a water supply, we found that being "generous" with the water will prevent that situation.

If we're hooked up to "city" water, our bathroom routine is different. We put water in bowl first, then double flush afterwards. That seems to eliminate the problem.

Good luck!
