7 Things You Should Know About Your Dometic RV Toilet

Your toilet is one of the most important features of your motorhome because it’s what separates a luxurious motorhome experience from a mediocre camping trip. The creature comforts are what RV enthusiasts depend on for a top-notch experience. Therefore, it’s important to know a little something about the type of toilet you’re buying, how it works and how to troubleshoot any problems on the road with it. We’ll tell you what to look for in your Dometic RV toilet.

About the Brand

The history of Dometic RV toilets is actually quite interesting. The brand was started by a pair of Swedish engineering students who successfully used heat in their cooling mechanisms to create the first refrigerator around 1919. They began selling their invention under the name Electrolux and eventually the company gave the name Dometic to its leisure appliances including those used for mobile living. Eventually the demand for these types of products grew to the point where Dometic became a public company in 2015.

SeaLand is a marine industry sanitation company that was founded in 1984. Dometic acquired SeaLand in 2002 and then, beginning in 2017, their products began being sold under the Dometic name. These days, it’s safe to assume that Sealand RV toilets are truly Dometic RV toilets and vice versa. SeaLand focuses on toilets for boats but similar principles are used when it comes to design and function.

Troubleshooting

One of the most common problems with your Dometic toilets RVs is a clogged bowl. The clog could happen for a variety of reasons and the solutions are plentiful. But the easiest way to fix this on your own is with a pot of boiling water. Begin by shutting off the water connection to your RV’s toilet. Then simply boil some water on your stove. Pour boiling water into the bowl and let it flush down. Believe it or not, this simple method often works better than the chemicals and tools they’ll try to sell you for this simple fix.

Dometic RV toilet replacement parts

You can find most of the replacement parts we’ll reference in this article online, through the Dometic site itself, or through a third party vendor. And if you can’t find them online, many brick-and-mortar RV and accessories shops will supply them.

Installation

Dometic toilets are easy to install and you can likely do it yourself. The first step, of course, is to turn off the water supply line and drain the lines. Remove the old toilet from the floor by loosening the side bolts screwing it into the ground. You’ll see the seal keeping it anchored to the ground. This is called a floor flange seal. The toilet will sit down on top of the seal. You’ll tighten the toilet to the ground by securing the bolts and nuts to the T bolts on the side of the toilet. At this point you can turn the water supply back on to test for leaks.

Cleaning and Maintenance

You’ll want to clean your toilet on a regular basis to avoid problems and to maintain a sanitary bathroom. We recommend using the sprayer wand to remove all soiling from the bowl between uses. On a regular basis, you should also clean your Dometic RV toilet with a simple RV bathroom cleaner. Remember that because your Sealand RV toilet is actually made of plastic instead of porcelain, it will be slightly more difficult to clean.

When cleaning, pay special attention to the foot pedal and the hand flush as this is where bacteria resides.

You’ve likely also experienced problems with the smell from your black water tank. To fix this, you’ll have to do a deep clean of your black water tank and the toilet itself. We recommend using a product safe on septic tanks that will break down human waste.

How it all works

There are several Dometic RV toilet parts that all work together to keep the thing running. The toilet itself is made out of plastic, which keeps the overall weight of the RV and its contents low. Many toilets are operated by a pedal at the base of the toilet. The pedal either fills the bowl with water or opens the valve into the holding tank, releasing all contents from the toilet into the tank for later dumping. Some toilets use a hand flush instead, but it works similarly in that it both fills and empties the bowl.

A common problem is a broken seal. You can easily find Dometic RV toilet seal replacements online.

Your Dometic and SeaLand RV toilets will also have a water module, which hooks the actual toilet up to the water supply in your RV. When troubleshooting, this is the module most commonly responsible for leaks.

Many Dometic or SeaLand RV toilets also have a hand spray kit. This spray wand removes stubborn stains and soiling from the toilet bowl so flush down.

Shopping

These days you can buy a new RV toilet just about anywhere, from the brick-and-mortar RV shops where you purchased your actual camper to third party sellers online. That makes it easier than ever to compare prices and make sure you’re getting a great deal. We also recommend spending a good bit of time investigating on your own. Start by reading comments left by other buyers to make sure you’re getting a functioning product worth its price tag.
