Do you own an RV or do you intend to rent one when going on holiday? There are a few things you need to know about RV tanks before they mess up your trip.
There are three tanks in an RV:
- The first one is a Freshwater tank that stores fresh water.
- The second is a grey water tank that holds dirty water from your kitchen sink and shower.
- The last one is the black water tank. It holds dirty water from your toilet.
Some RVs might lack a Grey tank, the black tank contain all the dirty water from the kitchen sink, toilet, and showers.
In this article, we shall focus more on the black water tank.
How to Maintain Your Black Water Tank
Since the black water tank holds the wastewater that is coming from your toilet, you shouldn’t mess around with it. Here are a few ways you can maintain it.
1. You don’t want to risk clogging your toilet. Then avoid using two-ply toilet paper. You should strictly use single-ply toilet paper.
2. Flush regularly – It is advisable that before flashing, ensure that you first add some water to the bowl of your toilet; then flash.
3. After dumping the waste, you need to sanitize the tank. Sanitization requires special chemicals. They are available in any big box store in the RV section.
4. Ensure that your tank is always clean. Your garden hose can help you to flush the system and clear up any build-ups. You’re required to put it down the toilet.
In case you realize that your black water tank is leaking, you have to get the solution faster. It can cause severe health issues. You can either decide to replace it or repair it.
Replacing can be expensive. You can choose to fix it before you invest and replace it later. Here are the steps you need to take.
1. Assess the Damage
In most cases, a damaged valve is the one that causes water leakage. The leakage also could occur if the tank has a crack. Repairing the valve and the crack is easy.
The hardest part will be if the leak is a result of the ruptured tank.
A ruptured tank means that your tank has exploded and cut split into two. Repairing that would be tricky and almost impossible since the damage is severe.
2. Fix a Crack
If you realize that the damage is a result of the crack, you have to sock the waste in your tank using sawdust.
The sandpaper will help you to smoothen that side of the crack. At the edge of that crack, add acetone and clean it thoroughly.
Apply a specialized sealant and let it dry. You can quickly get the sealant in the local repair shops. Since there could be excess sealant, you can use a cloth to wipe it.
You will realize that some service centers will not encourage you to repair your tank. Instead, they would like you to replace it. Reasons are:
- They will make more profit if they sell a new one to you than when they replace it.
- In case the repair fails, you might have a negative image of their business.
- Some don’t know how to repair the tank, or they don’t want to.
Why Do RV Black Tank Leaks When Full?) Replacing the Tank
You can decide to replace your tank. You have to know the kind of material that it
is made of. Then you have to go shopping for such a tank.

You will be lucky if your tank falls into this category since it has a few days’ leads and shipment time.
