Why It's Important To Fill Your RV Toilet Before Your Use It. Unique Camping + Marine

Here at Unique Camping + Marine, we talk a lot about using plenty of water in your black water holding tank. In fact, water usage is one of the most crucial aspects of proper holding tank care. If you don’t use enough water, you set yourself up for tons of issues, some of which we will cover in this guide. 

This article will outline the importance of water usage and give you all the reasons you should fill your toilet with water before flushing it!

Filling your toilet before each use ensures that you’re using plenty of water

The primary reason we recommend that you fill your toilet bowl before you use it is to make sure you’re using plenty of water. By filling your toilet bowl with water before flushing, you regularly add significant amounts of water to your tank. However, while filling your toilet bowl with water is important, there are other ways to regularly add water to your tank. In addition, we also recommend holding your flush pedal down for at least 10 full seconds every time you flush your toilet.

Filling your toilet with water before you use it will help waste flow smoothly down your line

The last thing you want while RVing is a blocked toilet line! This occurs when toilet paper and/or waste get stuck in the pipe between your RV toilet and your holding tank, causing a clog. By filling your toilet with water before each flush, you make sure that waste and toilet paper flow freely and smoothly down your toilet line. (To learn more about a blocked line and how to fix it, check out this article!)

Filling your toilet before you use it will help hydrate the bacteria in your tank, improving waste breakdown and odor elimination

You probably already know how important it is to supplement your black tank with a high-quality, bacteria-based holding tank treatment product. But, like any living organism, bacteria require plenty of water to thrive. In order for any type of bacteria holding tank treatment to work to the best of its ability, it’s absolutely critical that you use plenty of water in your tank! Water helps hydrate the bacteria, improving their efficiency in breaking down waste and allowing them to reach all the areas inside your tank. Again, by filling your toilet with water before flushing (in addition to other methods), you ensure that you’re using plenty of water!

If you’ve read any of our previous blogs, you know that we talk a lot about not only using a bacteria-based holding tank treatment, but also utilizing one that contains aerobic bacteria and enzymes. Unlike anaerobic bacteria (which produce disgusting-smelling hydrogen sulfide gas) aerobic bacteria only produce CO2 and water as byproducts. This means great waste breakdown with less smell. Still, aerobic bacteria need plenty of water to work effectively, which means that you should still fill your toilet with plenty of water before flushing it. (Check out this article for more information about why you should use a high-quality waste digester product.)
