A water tank is an essential part of every motorhome. This element is important if you wish to enjoy the experience of camping in a movable home. Without it, travelers would not have the privilege to enjoy freshwater in their taps and no bathroom to go to in their vehicle.
But how can it be possible for diesel to reach your water tank? If you own a motorhome, and you’re asking yourself this question, you would most likely want to know more details on how to take care of your water tanks when accidents like these happen.
Can Diesel Get Into a Motorhome Water Tank?
Absolutely. Water tanks, just like any other type of container of liquids, risk suffering from a fuel leak. Many times it is the owner that commits the mistake of filling the tank with diesel.
There are times in which the lid itself gets contaminated, and as a result, it ends up corrupting the water inside the tank. Although rare, this does happen to people that own or rent motorhomes throughout the year.
Depending on the type of material the tank is made of, or if the damage is too severe, it is ideal to replace the tank and call for a professional to fix the problem.
If there is diesel in the water tank, it is good to know that oil-based liquids and water do not mix, but it does contaminate the tank itself. People in the motorhome might experience the smell of combustible in the tap water and the taste of diesel in their drinks, which can result in intoxication.
How Can Diesel Get Into a Motorhome Water Tank?
There are various ways in which diesel can get into the water holding tanks. Sometimes, while filling the water tank, one can mistakenly fill the motorhome water tank with diesel that can ultimately disperse in the tank, contaminating the water and the walls of the container.
Diesel can also get into a motorhome water tank by using a contaminated hose. It is human error that can happen to anyone, from employees in charge of cleaning the water tanks to the owners. Still, diesel in your motorhome water tank can affect, as mentioned before, the health of your passengers and vehicle.
Diesel, just like most fuels, is a substance that doesn’t mix with water. It instead floats and stays on top while the water remains at the bottom. Unfortunately, this causes the fuel to also integrate into the walls of the tank, making it even more difficult to clean.
Bacteria can grow on the water tank itself, causing it to rust or even creating physical damage if you have a tank made out of steel or aluminum. But these types of tanks are usually easier to clean off than fiberglass tanks due to their material.
How to Prevent Diesel Getting Into a Motorhome Water Tank
Although it is unpredictable how often these types of occurrences happen, it is possible to prevent diesel from getting into your motorhome water tank. Here are some ways you can prevent this from happening:
- Always check if the tanks themselves do not have any physical leaks. There are times in which diesel leaks and contaminates the water.
- Before inserting the hoses into the water tank compartment, it is important to check if the hoses are clean. This will save you a lot of trouble in the future, and you won’t have to risk inserting corrupting agents into the water.
- It is advisable to use labeling signs that will allow you to recognize the differences between the fuel and the water tank compartments. If this mistake happens to you, consider revisiting the procedures for refueling.
- And always, ALWAYS sanitize the motorhome water tanks at least twice a year. However, if you travel regularly, it is better to sanitize your motorhome at least once a month for better results.
By developing these preventive habits, you should significantly reduce the risks of suffering from a diesel leakage.

The temperature of the water can be about 50 to 60℉. After that, pour the powder or the non-foaming agent into the water.
Wait A Few Hours Before Draining
For a most effective clean during these hours, taking your motorhome for a drive can help you slosh the water inside the tank. Try taking it to high places such as slopes, or curves for a better slosh.
