Black tank and toilet paper and chemicals

I have kind of a gross question. What kind of toilet paper do you use in your camper? We have been using Costco brand toilet paper and the chemical that comes in individual plastic packets. We have found that we're having issues with the black tank. It seems that when we empty it not all the stuff empties. Especially the toilet paper and sludge. Gross I know, sorry. We bought a 4 pack of the Thetford toilet paper and used the same chemical packet and it did seem to work better. So, we're wondering if others have any tips they can share.

Thanks,

Karen

  • RV TP is overpriced one ply sandpaper.

    X2 PenMan. don't dump until nearly full. If you have to dump a tank that is only partially full, drive to
    The next dump station down the road or make a lap around the CG then dump.

    The shake test the ScottG refers to is to put three sheets of the TP in to a jar half full of water, shake it, if it breaks up it is ok to use. Some two ply will also breakdown quickly. Sorry, I don't remember who the OP for that tip was, to credit him with it, but it works.
  • I have the Coleman stuff that I bought bulk on sale two years ago, when it is done I will switch to Scott's single ply. I use Kirkland (Costco) at home with a septic tank, it would be a little disturbing to find that it does not break down very well (not so easy to see that in a septic system)

    On the last night of camping, I pour my dirty dish / soapy water down the toilet and I pour extra fresh water down the toilet until the black water tank is basically full. I have found that 18 hours or more of water inside the tank breaks up a lot of the sludge. I have a clear elbow and can see the difference (yuck!)between a soak and non-soak dumping.

    *edited for spelling*
  • Single ply, lots of water. Do not put anything else in the tank. No butt wipes.

    A long time ago someone on here did a comparison between TP's by putting them in a jar of water overnight (IIRC) and also by shaking them slightly. They found that no two ply TP broke down very well. They also found that even some single ply didn't deteriorate while others did.
    I remember Costco didn't do too well but Scott's single Ply and "RV" TP both did well. I think there were other brands that worked good too but I forget which.


    IIRC the Costco tp and the Scott were the two that dissolved best. That is why we switched to the Costco brand. Costco has recently come out with some tp that feels more like cloth. I will not try it in the TT.
  • I have never used special TP or chemicals for that matter. I do use an internal sprinkler on both my tanks when I dump. Never had a problem. If your tank is ve3nted properly why on earth would one use chemicals? Maybe in a hot humid spot you are staying for a week or so? I know we have had dump stations near us closed due to excessive chemical use so I am told by ODOT. bEST OF LUCK

  • We use the Costco tp and have not had any problems. The main trick is to make sure your black tank is almost full before you dump it even if it means holding the toilet valve down for five minutes letting it get full. We also have a tank cleaner installed (don't know what brand as it came standard with the Open Range but had a Tornado on our last trailer) and use it every time we dump the black tank. We do use chemicals too (a liquid) but I don't remember what brand. If your tank has solids built up now, you may need to use the Geo method (do a search) to get it cleaned initially and then try what I have suggested. Happy camping.
