    What causes clogs in your rv toilet?

    • The pyramid plug
    • This is when poo and toilet paper build up and causes a clog. Most clogged RV toilets are caused by pyramid plugs. A pyramid plug is a build up of of poop and also toilet paper that has developed from all-time low of your black water tank and formed a pyramid type of ickyness that has actually now reached your toilet. This is a regular cause of a clog in rv toilets. Many people inaccurately assume that their holding tank or tanks are full when in fact it is clogged. For a few individuals, this may certainly hold true, however, for most individuals, the offender is not an entirely clogged tank yet, just simply a pyramid of waste.

    • Feminine items: They can cause the toilet to clog
    • One of the most common causes of clogged toilets is feminine items. They include sanitary pads, tampons, wipes, and other similar products. These items are not suitable for toilets because these are bulky and can get stuck in the pipe. Even if you flush them with water, these can also get stuck in the RV’s sewer system or septic tank.

    • Q-tips: They can block your toilet as well
    • You might not know it but q-tips can clog your toilet too. Just like feminine products, they are designed to be disposed of properly because they are bulky and they do not dissolve in water easily. As a result, they can get stuck in the pipes which will lead to a clogged toilet.

    • Your RV toilet is not a trash can.
    • Things like plastic containers, cigarette filters, cotton balls, and other trash should never be flushed down the toilet. These items can build up in the plumbing system and create a clog.

    • Paper Towels and Wipes
    • Do not flush paper towels or wipes down your RV toilet. These cloth-like materials don’t break down like toilet paper and will get stuck in your plumbing system. This is a common cause of clogs in the black tank.

    • Foreign Objects
    • Anything that shouldn’t be flushed down a normal toilet shouldn’t go down an RV toilet either. Diapers, feminine products, cat litter, and even toys can lead to clogs that cause a backup in your plumbing system.

    RV toilets are made to work just like your home toilet, as long as you follow some basic rules.

    • Don't put anything in your RV toilet that's not human waste or RV toilet paper.
    • No grease, no paper towels, no feminine products, no kitty litter ... nothing. Only use RV toilet paper.
    • Make sure the holding tank is empty before you travel, so you don't slosh around and make a mess inside the tank and the toilet bowl.
    • Don't leave your RV in storage for long periods of time with liquid in the holding tank. If you do, it will start to stink after a while and could possibly break down the seal in the black water valve.

    Hopefully you never have to deal with this, but if you're reading this I can only assume that you do. I also hope that it's not too late (after the fact) and you haven't launched a search engine query to "unclog an rv toilet". If so, then i hope this article saved you some time.
