Trying to find the best RV portable waste tank?
Investing in a portable RV waste tank is one of the best ways to enjoy boondocking or staying at RV parks that don’t have full hookup. They allow you to dump your black and grey tank waste into the portable tank and then dispose of it at a later time. Portable waste tanks aren’t necessarily required, but they’re an excellent commodity to give you more traveling opportunities and freedom.
If you hope to purchase the best RV portable waste tank for your needs, there are several things to keep in mind. First and foremost, your tank has to be readily portable and compatible with your RV. It should also be lightweight and durable and form an airtight seal so that none of the waste or the smell it emanates can escape.
In addition to listing some of the best RV portable waste tanks on the market, this article will also offer a buying guide to make your decision as easy as possible. By using our buying guide or choosing one of the options you’re about to see on this list, you can be sure to have one of the best RV portable waste tanks on the market.
How to Choose the Best RV Portable Waste Tank
Type of Tank
One of the most important things to keep in mind when choosing your tank is that there are three different types. There are tanks that are only designed to hold gray waste, tanks designed to hold black waste, and tanks that can hold both. If you want an all-purpose portable waste tank rather than two individual ones, make sure to purchase one capable of handling black and gray waste.
Size of the Tank
The smaller your portable tank is, the more often you’ll have to dump it. However, if you choose a tank that’s too big, you’ll have a hard time storing it and transporting it when dumping time comes. Therefore, you would do well to find a happy medium between too big and not big enough.
Material of the Tank
Traditionally, portable waste tanks were made of a wide range of materials. However, manufacturers have found that a mixture of plastic and polyurethane are the best materials to use for waste tanks. They’re lightweight enough to easily transport but durable enough to withstand heavy use. Plastic and polyurethane is also UV-resistant and don’t crack or corrode easily.
Price of the Tank
No matter how good or durable your waste tank is, it’s not going to last forever. They go through a ton of wear and tear and get beat up on. Therefore, you shouldn’t spend too much money on your portable waste tank because it’s probably going to give out anyways. However, you want to find a happy medium and make sure to spend enough to get a quality product.
Ease of Use
No matter how tight your budget is, you’ll want to invest in a portable waste tank that’s easy to use. Your tank should have a flush valve where you can easily hook a hose up to, making it quick and simple to eradicate your waste. Without a flush valve, you’re going to have to manually flush the tank which takes time and work.
How Does a Portable RV Waste Tank Work?
The key to using a portable RV waste tank is to not overthink it. You should think of it simply as a go-between for your RV and the dumping station. Here’s a step-by-step look at how to hook up your portable waste tank and how to dump it when it’s full.
- Connect the sewer hose from the sewer port on your RV to the sewer hookup on your waste tank.
- Open the flush valve on the portable waste tank to allow gray and black waste to flow from your RV holding tanks to the waste tank.
- Close the valve when the portable tank is full.
- Close the valves on your RV holding tanks so that waste doesn’t run out when you disconnect the hose.
- Disconnect your sewer hose from the portable tank and RV tanks and put it away.
- Take your portable tank to the nearest dumping station and dump the contents of the tank. You can use your own sewer hose or one at the dump station.
- Make as many trips as necessary to empty your black and gray holding tanks in your RV.
