Black water tank not draining on park model

[Madmike]

Hi we just bought a new dlx qbq wildwood 42 ft park model trailer. I can't seem to get the blk water tank to drain. It shows empty on the display but when I look in the toilet into the tank I still see paper and the other stuff . The drain doesnt look right. The bottom of the tank looks like it is below the drain . I am worried with close up season coming . That there will be hold up of paper and poop. And freezing to cause a crack in the tank. Any ideas would be helpful.

If you don't have a built-in black tank flush, get a wand sprayer and stick it down into the tank. Its probably reading empty because there's no water in the tank but you've still got some stuff stuck to the bottom.

Assuming you're on full sewer, you may have to fill and drain it a few times.

and then keep the valve closed until the tank is full, then drain, if you're not doing that already.

Possible you got a tp clog at the out pipe of your tank. Try what the others said add a bunch of water and pull the valve. If you hear or don’t see the pipe slinky move propably clogged. If you get a little trickle probably clogged. I had to dump 2 5 gallon pails of hot water down my old keystone toilet and waited about 10 mins then pull the valve. Good thing I had one foot on the hose because when that clog cleared the hose jumped a bit as it all wanted out and fast. Worst case put a call into the chat office have the sucker machine come and give it a suck.

Most common problem for new owners! You have a pile up under the toilet because
You probably have opened the black water drain and left it open.
You MUST leave the drain valve closed during usage. This allows the water to build up in the tank and keep the solids from pile up and solidifying. It will allow the collected water to flush everything out when the valve is opened.. it’s also a good idea to refill a few gallons into tank after dumping.
For now if you can see directly down into the tank, run a hose inside wth a nozzle and blast the tissue loose and fill to top then pull drain valve..

Post pictures! If the bottom of the tank is below the drain, you do have a problem.

Weeeelllllllll......when our seasoned RVing buddy heard I'd bought a TT, he took us to a local state park to teach us some basics, for when we picked ours up. One thing he told us: "No pooping in my trailer." He just didn't want to have to deal with the issues you mentioned above.

We adopted that (and more) using these options:
1. Peeing only in our toilet. Females-put toilet paper in the provided zip-lock baggie, place in trash can beside commode.
2. Pooping- Use bathroom facilities provided at campsite, if available.
3. If not available, place double trash bag under the commode seat, poop, tie bag up and drop in bucket outside front door for soonest disposal. Originally, we added kitty litter to the bag but found it was an unnecessary step.

I'm a female... it's no thing. So Ladies, if this makes you squeamish, consider having to be the one to clean up a clogged black water tank. My guess, you'd rather grab the bags and get 'er done!.

My brother-in-law was the same way with his motorhome. I figured it must be really ugly dealing with black water. When we went houseboating on Lake Powell, I found out that the problems are greatly overblown. Twenty years later, and I've never had any issues with either black tank. We use TST from Walmart in our houseboat, and the Geo Method in our Roo. Easy Peasy. It sounds to me that the OP may have a warranty problem. That's easy too. Take it back to the dealer.

It's funny when i hear people won't use their black tank as designed . why use it at all ? when done correctly you can use the back tank to it's full potential without issues . i've been using mine for 5 years full time cross the country twice a yr and never any issues . why even have it if you're afraid to use it ?

There is a reason a toilet is installed. USE it, POOP and paper in a baggie?? Crazy!!!!! I have been pulling campers with toilets since 1976 and boats with toilets since 1989. Never had a single problem. All it requires is common sense which seems in short supply today.

That right there is the answer! It's a toilet with a holding tank. It works as designed. Don't try to reinvent the wheel! Fill bowl with water, POOP, wipe and drop it into the toilet. Would you ask your guest to use bags at home!!!!!! YUCK!

X2. Just to add, 2ply TP is actually better than RV toilet paper. Just make sure you put more water in bowl before unloading yourself. Wife has taken it upon herself to deposit some dishwater waste into toilet occasionally especially when boon-docking and she has a small garbage container for TP for #1 which she empty’s daily.

Thanks for your help I did a second flush and it seems to have cleared we are hooked into sewer system with solid pipe . My neighbor said that he doesnt think the line drop is enough to drain the tank completely. So I am flushing the tank out 2 times after a initial pull of the valve.
