This topic isn’t something you should talk about in polite company, but it is an essential component to operating an RV. It also tends to be the question that looms largest on a rookie RV user’s mind: What happens when you use the bathroom?
The answer is that it stays in your wastewater tank until you empty it. You should empty the tank every time you’re at a site with a dump station, because if you wait too long, it runs the risk of getting stinky. Also, treat your toilet with deodorizer to keep things smelling fresher.
Ask the RV owner to show you how to empty the tank. You’ll definitely want to use disposable gloves, and stay vigilant when you open the tank—there’s likely to be some unsavory leakage when you unscrew the cap. Finally, empty the gray tank after you empty the waste tank to help clean out your hose. Rinse the hose a final time with clean water from the site’s water hookup for good measure.
If you’re not staying somewhere with a dump station, many truck stops and travel centers also have them. You can also pay a small fee to stop at an RV park just for dumping services. Sanidumps.com, RVDumpSites.net, and RVdumps.com all offer a comprehensive list of available dumping locations.
And if this whole process sounds like the worst thing you’ve ever heard, an increasing number of RV parks and campgrounds are offering to empty guests’ tanks for a small fee. Give it a try yourself first, though. You can do it!
