RV Portable Waste Tank

What Is An Portable RV Waste Tank?

An RV portable waste tank is a device that allows RVers to store their gray water and black water until they can find a place to dispose of it properly. There are many different portable waste holding tanks on the market, so it’s important to do your research before buying one.

Who Needs An RV Portable Waste Tank?

RVers want to store their waste until they find a proper disposal location.

Many RVs come with a black or gray tank installed. RVers who don’t have a built-in tank will need to purchase a portable waste tank.

RVers want to camp in more remote locations without worrying about finding a proper disposal location for their waste. If you plan on camping without sewer hookups, you will need to dispose of your waste properly. It is not always convenient to move your entire rig whenever you want/ need to dispose of waste. In these types of situations, it is much more convenient to have a portable RV waste tank.

Features To Look For In A Good RV Portable Waste Tank

When you are RVing, there will be times when you need to store your waste. That’s why it’s important to have a good RV portable waste tank. Here are some of the features you should look for:

– A durable construction that can withstand being dragged across rough terrain

– Wheels for easy transport

– A hose and fittings so you can easily empty the tank

– A capacity that meets your needs – you don’t want to have to empty the tank too often

– A level indicator so you can see when the tank is getting full

– A warranty in case anything goes wrong with the product

What Size And Style of Tank Do You Need?

There are many different sizes and styles of RV portable waste tanks to choose from, so it’s important to know what you need before you buy.

You will need to purchase a portable waste tank that is the same size or larger than your RV’s black water tank.

If you plan on camping in more remote locations, you may want to consider a larger tank, so you don’t have to empty it as often.

You will want to make sure to choose one that can have a high enough capacity to hold enough waste and is easy to move around.

Which Is Better Two Wheels Or Four Wheels?

This is a matter of personal preference. Some RVers prefer four-wheeled portable waste tanks because they are easier for transporting the tow tank and don’t tip over easily. Others prefer a two-wheeled portable waste holding tank because they are lighter and take up less space.

What Materials Do Waste Tanks Come In? What To Choose?

ABS, polyethylene, and polypropylene plastic are the two most common RV portable waste tank materials.

ABS is a lightweight, brittle plastic that is not as durable as polyethylene.

Polyethylene is a more durable, heavier plastic that can withstand colder temperatures.

Polypropolene is a lightweight plastic resistant to chemicals and won’t absorb odors.

Choosing a durable material that can withstand being dragged across rough terrain is important. You will also want to make sure it can withstand the weather conditions in the area you will be RVing in.

When choosing an RV portable waste water tank material, you will need to consider the climate you live in and how often you plan to use your tank.

How Do You Transport Your RV Portable Waste Tank?

This will depend on the type of RV portable dump tank you choose.

If you choose a tank with two wheels, you can transport waste by carrying it or dragging it behind your RV or golf cart. We have seen people pull them behind their trucks. Be careful of speed. You could end up with quite a mess if you cause damage to your tank or hit a bump.

If you choose a tank with four wheels, you can transport it like a suitcase – wheel it around.

Read the manufacturer’s rating for towing. Most have instructions for speed and have a max tow rating set to 5 mph.

If you have a ramp, you could transport your tank to the bed of your truck.

How To Empty Your Tank?

  • Connect the sewer hose to the sewer drain.
  • Open the valve.
  • Open the vent hole (this will allow air to flow).
  • Once empty…close up shop. ***see video for more info.

How Do You Clean Your RV Portable waste Tanks?

If you’ve ever had to clean your RV’s black water tank, you know it’s not the most fun task in the world. But it is necessary if you want to keep your RV smelling fresh and looking clean. The same goes for portable waste tanks.

There are a few different ways that you can clean your portable tank. You can use a hose to flush it out or a plunger to suction the waste and fluids out. If you have a massive tank, you may be able to get away with just using water to rinse it out.

But if your tank is smaller, or if the waste is caked on, you’re going to need to use some cleaning solution. RV holding tank treatments are made specifically for this purpose and will help break down the waste and make it easier to flush out.

Once you’ve flushed out your tank, it’s a good idea to rinse it out with fresh water. This will help eliminate any residual waste and cleaning solutions left behind.

And that’s all there is to it! Cleaning your RV’s portable waste tank is not the most fun task, but it’s definitely something needs to be done regularly. Follow these steps, and you’ll have no trouble getting the job done.

When it comes to RVing, there are many things that you need to know to do it correctly. This includes everything from properly hooking up your RV to dumping your waste tanks. And believe it or not, there is etiquette involved in dumping your tanks. Who knew?

Here are a few do’s and don’ts when it comes to RV dumping etiquette:


-Dump your tanks in a designated dump station,

-Clean up any messes that you make while dumping

-Be courteous to others who are using the dump station

-Use gloves. Don’t spread germs

-Block other RVs from using the dump station

Following these simple guidelines will help the RV dumping process smoothly for everyone involved. So next time you need to dump your tanks, be sure to keep these etiquette tips in mind.

How Often Do I Need To Empty My Tank?

This question can be difficult to answer, as it depends on various factors, including the size of your tank, the number of people RVing with you, and how often you are using your RV’s facilities. But as a general rule, you should try to empty your tanks at least every other week.

If you’re RVing in an area with no dump stations available, then you’ll need to empty your tanks more often. And if you have a large tank, you may be able to go longer between dumps. But it’s always best to err on the side of caution and dump your tanks more often rather than less.

No one likes having to deal with a full RV waste tank, so it’s best to avoid it if at all possible. You should keep your tanks empty and your RV smelling fresh and clean by following these guidelines.

What Happens If I Let My Tank Get Too Full?

If you let your RV waste tanks get too full, the consequences can be pretty unpleasant. Not only will it make your RV smell bad, but it can also cause damage to your RV’s plumbing system.

The best way to avoid this is to monitor your tank levels and dump your tanks when they get close to full. This will help ensure that you never have to deal with a tank that’s overflowing with waste.

How Do I Find Dump Stations Near Me?

RV dump stations can be found in many places, including RV parks, rest areas, and even Walmart parking lots. You can also find a list of RV dump stations online or using several different apps.
