If you're planning to take a road trip in an RV, one of the essential things you'll need to know is how to use the toilet. While it might seem like a simple task, RV toilets work a little differently than the ones you're used to at home.
To make sure you're prepared for your trip and to avoid any unpleasant mishaps while you're on the road, we've put together this guide on how to use an RV toilet.
Let’s get started.
The most common type of RV toilet is the gravity flush toilet, which uses a combination of water and gravity to create pressure for flushing. Gravity flush toilets require a large holding tank for waste disposal and can add a significant amount of weight to your overall carrying capacity.
Typically found on Class A and Class C motorhomes, fifth wheels, and travel trailers.
The cassette toilet uses a removable container that can be quickly removed from the RV and emptied when full. Cassette toilets are easy to install and use minimal water, but they require frequent emptying and can be expensive to purchase.
Typically found on smaller RVs such as Class B campervans, micro trailers, and tent trailers.
Composting toilets use a combination of microorganisms to break down waste into compost, which is then later disposed of in an outdoor area. Composting toilets are relatively self-contained and require minimal maintenance, making them ideal for campers traveling to remote locations where access to water may be limited.
Typically found on truck campers, Class B campervans, and RVs meant to spend extensive time off the grid.
RV toilets use less water than residential toilets, which helps conserve the freshwater supply and the holding tanks onboard your RV.
RV toilets are made with lightweight materials, compact components, and smaller bowls than residential toilets, which means RV toilets can clog easily if you try to flush too much waste at once.
In most RVs, you have to manually fill and flush the toilet instead of simply flushing the toilet like you would at home. But, don't let the word manual scare you; it's actually easy to use an RV toilet once you know how!
The steps to use a gravity flush RV toilet are as follows:
Pro tip. It's important to note that using too much water can fill up your holding tank more quickly, so it's best to find a balance between using enough water for proper flushing and not overusing water unnecessarily.
Pro tip. Only flush human waste, RV toilet paper, and RV tank treatment down the toilet. Flushing sanitary products, disposable wipes, or anything not approved for an RV toilet will damage your RV's plumbing and black water holding tank.
RV manufacturers recommend RV or septic-safe toilet paper because it breaks down better than regular toilet paper. Plus, it's less likely to clog the tank or plumbing system.
RV tank treatments, like Happy Campers or Unique RV Digest-It, help to control odor by breaking down toilet paper, human waste, and the bacteria that cause unpleasant smells. Using a tank additive also helps to keep your tanks clean and free from buildup, which can improve the overall performance of your tank sensors.
After emptying your black tank, fill your toilet with approximately 1 gallon (full bowl) of water, add the tank treatment, and immediately flush. For hot climates and tanks over 40 gallons, repeat the above and add two more gallons of water to the black tank.
Only flush human liquid and solid waste, water, RV toilet paper, and RV tank treatment.
As a general rule of thumb, you'll want to use enough water to fully cover the bottom of the bowl and create a seal before flushing. This method helps to prevent waste from sticking to the sides of the bowl and ensures proper drainage.
The RV toilet empties into the black water holding tank.
Most RVs have sensors that monitor the levels in your black water, gray water, and freshwater holding tanks. You can avoid what the RV community calls a poopsie by dumping your black water tank when the sensors indicate 3/4 or 75% full.
Yes. If your RV isn't connected to water, or you don't have fresh water in your holding tank, you can still flush the toilet by filling a jug or bucket with potable water and pouring it into the bowl before you flush. Make sure you add extra water down the toilet after flushing to put enough fluid in your black tank for your RV tank treatment to work correctly.
