4 Reasons Why Your RV Toilet Smells
Your toilet smells for one of four reasons:
- Your sewer tank is damaged.
- Your toilet is leaking.
- It has not been thoroughly cleaned for some time.
- You have created a clog.
In most cases, you can correct problems 2 and 3, but for 1 and 4 you will need a professional repair job, unless you are extremely handy and are willing to deal with a messy situation.
That Toxic Odor Has to Go!

More Info About RV Tank Odors
RV Toilet System Info
No matter the cause, you need to understand how RV toilet systems work.
Toilets Need Water
To function properly, waste matter must be mixed with enough fluid to keep it from drying out. These liquids come from urine, bathroom showers, and/or sink water. When the sewer tank is kept closed, the incoming water keeps the waste from drying out. But if you keep the line open, the liquids leave and most of the solids remain and eventually the system stops working.
You Must Use the Right Toilet Paper
The problem is made worse if you use regular household toilet paper because it does not biodegrade. Even if you use RV grade toilet paper, too much of it will add to the problem.
Flappers Must Be Able to Seal the Toilet
Furthermore, whatever is in the tank, clogged or not, must be sealed. The flapper inside of the toilet is what takes care of this job.
If the flapper breaks or becomes blocked so that it does not close all the way, the odor from the black water tank enters the RV and makes it smell.
The Toilet Must Be Kept Clean
If there are no clogs or leaks, but there still is a smell, the toilet itself is dirty. Despite the fact that RV toilets are made of heavy plastic, waste and dirt leavings still can cling to them, dry up, and smell.
So, unless you have a problem that requires a major repair, the items I just mentioned are easy to fix.
This product helps to avoid the nasty buildup on your RV sewer tank that causes that noxious tank odor.
Three Steps to a Sweet Smelling Toilet
1. Get Rid of the Clog
The lengths you must go to do a corrective clean out will depend on the severity of the problem. The worst case scenario happens when you try to empty the reservoir and nothing comes out. The fix for is not pretty, but it is the only way you can get rid of the smell. How to Clear an RV Toilet Clog shows you how to do this job.
The article I linked to above will tell you how to deep clean your system so that it starts working again and eliminates the odor.
You can hire someone to do this job for you, but it is not difficult and will cost nothing if you do it yourself.
2. Scour, Sanitize and Sweeten the Tank
- Once everything is moving again, you need to clean and scour the tank itself because all of that dry material is still clinging to its sides. Therefore, your toilet will still smell. If you read the article I have linked to above, it will tell you how to do this job, also.
- After you have done this, sweeten the tank with some Pine Sol or Spic and Span and a bit of water. Spic n Span is the better choice of the two because it will help to keep the inside of the tank scoured and free of the smelly debris that sticks to the tank's sides.
If you maintain and use the tank properly after doing this, and use the correct enzyme chemical, such as the one I show here, in it on a daily basis, you should only have to do a deep clean like this a few times each year.
We use this product regularly, and it does a great job of turning waste into liquid and keeping sludge from forming on the sides of the tank.
3. Clean the Flapper and Toilet
If you have done all of this and the odor persists, it is likely that the flapper inside of the commode is not closing completely. This often happens when bits of toilet paper get caught up under the rim.
- Thus, the best way to fix the problem is to take a rag, soak it well with water and thoroughly wipe around the area inside and under the flapper to release anything that may have gotten caught in it.
- If this does not work, you will have to hire a repairman or may even have to replace the toilet. However, that rarely is necessary.
- Before you make the call, though, clean the bowl, the inside rim and the top and bottom of the drop down seat thoroughly, because the smell may be due to the fact that those areas may just be coated with dried waste that has started to smell.
Protect and Maintain
These three simple steps should result in a complete and permanent absence of noxious odors in your unit.
However, that will only happen if you continue to use your toilet and waste water tanks and hoses correctly and keep them clean.
Repairs are expensive, but you can avoid them by following the advice both in this article and the one I mentioned earlier.
Start today, and within an hour and using this three step method, your RV will be free of toilet smell again.
