10 Best RV Portable Waste Tank Reviews to Buy in 2020


If you are one who loves the outdoors or do a lot of camping or stay extended periods of time in campsites without proper sewer connections, then the RV Portable Waste Tank is the ideal solution for you. It will allow you to dump your grey and black holding tanks without having to go to the nearest dumping station.


Portable black water tanks are available in 2 versions namely the 2 wheel and the 4 wheel tanks. The 2 wheel portable tank tanks are equipped with the wheels in the back.


These tanks are very heavy, so it provides you with the opportunity to lift and support it when it is full of wastewater. You can empty this tank while it is standing upright. The 4 wheels portable tank, on the other hand, is much less of a hassle to move because it rolls along without you having to hold it up, and saves you a lot of strain on the back. When you are dumping, you can leave your tank level and it will easily dump without any extra effort.


What’s the difference between the 2? The 2 wheel tanks are cheaper, but they difficult to drag across a surface that isn’t smooth. The 4 wheels black water tank is more expensive but is of higher quality. It will also spare you all the back pain for years to come.

There is plenty to consider when buying a portable waste tank. You don’t want to inconvenience yourself by ending up with something that you can’t use. Before you buy one, consider the following:

Type of Tank
Most tanks can hold black water and gray water waste. Some can hold only one. Make sure that you get what you need before you pay for yours.

Materials Used
Portable waste tanks are made from different kinds of materials, mostly plastic, and polyethylene. Plastic doesn’t often crack or get corroded like what happens with metal tanks. Polyethylene, on the other hand, has a thickness that lasts and keeps the bad smells contained and from getting out.

Ease of Use
It is important that your tank doesn’t clog. Make sure that your tank has a flush valve that will automatically flush your waste out of the tank.

When buying a portable waste tank, this should be your first priority. The more wheels it has, the better and easier it would be for you to move it around. Rubber wheels would be the best bet.

Length of Your Trip
For a weekend trip of 2 to 3 days, the 30 Gallon tank would be ideal, but for a trip that would last you for more than 3 days, the 40 Gallon tank would be the best bet.

Check reviews to determine the durability of your tank, and if it’s worth what you are paying for it. You don’t want to be paying too much for a tank that won’t last you very long
Frequently Asked Questions (FAQs) Barker vs. Thetford?

Although both do a good job, the Barker portable waste tank seems like a far more popular choice with very good feedback. The Thetford tote tank is a bit cheaper though.
What is an RV portable waste tank?
There are two types of water that you want to dispose of while you are in traveling in an RV– gray water and black water. Gray water is wastewater from the shower, sink, etc. Meanwhile, black water is collected waste from the RV toilet. There are several ways to dispose of gray and black waters, but the most effective on is using an RV portable waste tank.

An RV portable holding tank collects both waste liquids and solids from the RV. You can easily attach it to your RV and fill it up until it’s almost full. If you don’t want the tank to stink, you can add tank treatment chemical. Because it is portable, you can tow it towards the dump station, where you’ll dispose of the waste.

This tank is in demand among people who frequently go on road trips because it’s convenient and easy to use.
What are the benefits of RV portable waste tank?
Admittedly, emptying a septic holding tank is not an appealing task. So why should you do it instead of camping in a place with public bathroom facilities?

For one, there are destinations that simply don’t have an established camp. You can’t simply dump your waste in random areas. There’s also the chance that you have to go to the bathroom even when you are still far away from the camp. In both cases, an RV holding tank becomes handy.

Here are three benefits of a portable waste tank:

Convenient: Imagine waiting in line the sewer trap even if you really have to go to the bathroom already! The wait can be excruciating. However, you can avoid it if you have a holding tank with you. Yes, emptying its contents, later on, can take time, but you can at least do it at a time of your choice. Nature’s call, on the other hand, is not always in your control.

Environmentally-Friendly: There is a considerable amount of water that you can save as you learn to limit the amount of water you use according to the size of your waste tote. Also, it’s easier for you to measure water used if you do so by counting the trips you make to and fro the dump station. If you are to buy a waste tank, just make sure that it’s made from environmentally friendly materials.

Clean: Nobody likes a mess. You particularly have to be careful when you are camping with other people. Luckily, the waste tank can keep gray water and black water in a single location. As for the smell, you can control it by using a treatment chemical. Cleaning the tank comes easy as well. You have to empty the black tank before the gray tank so that you can use gray water to clean the first tank.

So you have a holding tank, why should you buy an RV tote tank? The primary reason for this is that bringing your RV to the dump station is not always convenient. Sometimes, the road gets too narrow. With a portable waste tank, you can easily navigate your way there. Here follow some commonly asked questions that you might have as well.
How to choose the right size waste tank?
When deciding the size of your portable waste tank, you must consider the length of your trip and your bowel health. How often do you have to go to the bathroom? How long will you be on the road trip? As much as possible, you have to buy a portable tank that will allow you to drain all the content of your gray and/or black tank into it.

If you want to be on the safe side, you can simply buy the biggest waste tank. However, this will add weight to your RV. Weigh in your options carefully.

First of all, wear hand gloves. Then, connect the sewer hose of the portable tank to the holding tank of the RV. Make sure that you are connecting it to the right valve; check the “gray water” and “black water” labels. Fasten the hose carefully. Then, you can start draining the tank.

Once the portable waste tank is full or after you’ve drained the RV holding tank, it’s time for you to close the portable waste tank. Pull or tow it to the nearest dump station.

After this, you can empty the waste tank. How to do it usually depends on the tanks manual. For standard waste tanks, you have to turn on the flush valve and let the tank drain. Wait until no more waste, liquid or solid, is coming through the hose.

Lastly, before you shut the portable waste tank back, you have to carefully clean it.

Note: If there are any spills during the transfer of waste from the holding tank to the portable waste tank, check all equipment. You might need an RV holding tank replacement or a better portable waste tank.
