Why You Should Keep Water In Your RV Toilet

Why You Should Keep Water In Your RV Toilet - Unique Camping + Marine

It can sometimes seem like a waste to keep water in your RV toilet bowl, which leaves many people wondering: Is it really that important to keep water in my toilet bowl all the time? 

Here at Unique Camping + Marine, we believe that the answer is yes! We strongly recommend that you keep several inches of water in your toilet bowl during your RV trip, and in this short article, we’re going to tell you why.

Keeping several inches of water in your toilet bowl will create a water barrier preventing disgusting smells from seeping up into your RV living space.

Have you ever noticed the shape of the pipe on your home toilet or wondered how sewer smells don’t enter your home through your toilet? Well, the answer lies in how the pipe and toilet bowl hold water. Home toilets come equipped with a p-trap (a pipe shaped like a p) connected directly underneath the toilet. The pipe has a low point to catch and hold a small amount of water every time you flush your toilet. Water in a highly effective sealant against nasty smells, and this small water barrier blocks sewer odors from entering your home. Just to be safe, home toilet bowls also automatically refill with water, creating yet another water barrier against foul smells. 

The same concept applies to your RV toilet. The only difference is that the water does not add automatically to your toilet bowl. Instead, you have to add the water to your toilet bowl manually. Simply press your flush pedal down partially so that water begins to flow into your toilet bowl but not so much that your valve opens. This will allow you to fill your toilet bowl with water without flushing the water down your RV sewer line.
