While there’s not too much that can go wrong when it comes to the pretty simple appliance that is an RV toilet, there are a few things you should know about your toilet in order to properly troubleshoot the rare problem that might arise. Trust us, you don’t want to be unfamiliar with your toilet when you’re somewhere up a mountain in negative temperatures and discover that the bowl won’t hold water…

You’ll typically only have to worry about one key part of the RV toilet, and that’s the seal that separates the basin from the drain and retains water. This little component is liable to become clogged if you flush anything that ought not be flushed, and it’s also prone to cracking when left for long periods without use. In this quick lesson, RV expert Dave Solberg teaches you about some of the things you should be aware of when maintaining an RV toilet, including what to do in the vent of a clog or seal crack.

Pre-Trip Checklist

The dos and don’ts of an RV toilet

From time to time you may encounter an issue with your RV toilet, such as when the seal doesn’t seem to want to close completely, which results in a half-full or empty basin. To help you take care of this problem, Dave introduces the common causes of a malfunctioning toilet, as well as what to flush and not flush, and then he teaches you a simple trick to troubleshoot a faulty seal.

First things first, never flush paper towels down and RV toilet (or any other one, for that matter). Let’s just get that out of the way. Secondly, to avoid serious issues down the road, always take action at the first sign of a clog. Dave teaches you how to use a common household implement to get this job done. Furthermore, as soon as you see evidence of a seal or valve that won’t properly hold or shut, do yourself a favor and apply toilet seal lubricant and conditioner. Or if you’d like to avoid the added cost, some vegetable oil will do in a pinch. This is equally important when winterizing your RV for a roadtrip late in the year or storing it for hibernation.

Oftentimes a faulty seal occurs through no fault of your own. In certain parts of the country you’ll utilize hard water that can cause lime buildup along your drain and pipes. For that issue, there’s CLR. A healthy dose of this magic mixture, and your problem will be quickly solved!

In addition to clearing any blockages and treating lime buildup, you should also be sure to check your toilet and its components for any cracks that can lead to leaks. The attached sprayer is a common culprit, so Dave recommends a couple of solutions if you discover a faulty or leaking sprayer. With his simple tips, you’ll be able to shore up any problems with your RV toilet, and you can guarantee to give it a long lifespan and get your full money’s worth!
