Buying Guide
Choosing the right portable waste tank depends on a few key factors. Here’s what to consider:
- Capacity: How much waste do you typically generate between dump station visits? Choose a tank that can handle your needs. Consider the size of your RV and the number of people traveling with you.
- Durability: Look for a tank made from heavy-duty, puncture-resistant materials. RVing can be tough on equipment, so you need something that can withstand the wear and tear.
- Portability: Consider the weight and size of the tank, especially when full. Look for features like wheels and a tow handle to make it easier to transport.
- Ease of Use: Choose a tank that is easy to hook up, empty, and clean. Look for features like auto-stop valves and clear level indicators.
- Storage: Think about where you’ll store the tank when it’s not in use. Smaller, more compact tanks are easier to store, but they may not have the capacity you need.
- Budget: Portable waste tanks range in price from around $50 to $300 or more. Set a budget and stick to it, but don’t sacrifice quality for price.
Also consider the type of camping you do. If you’re mostly at campgrounds with full hookups, you might not need a huge tank. But if you’re boondocking frequently, a larger capacity is essential.
FAQs
Q: How do I clean my portable waste tank?
A: Rinse the tank thoroughly with water after each use. You can also use a tank cleaning solution to remove stubborn residue and odors. Be sure to follow the manufacturer’s instructions.
Q: Can I use a portable waste tank for both black and gray water?
A: It’s generally recommended to use separate tanks for black and gray water. Black water contains human waste and requires more thorough cleaning. If you must use the same tank, be sure to clean it very thoroughly after each use.

A: Most portable waste tanks have a hose that you can connect to a dump station. Make sure the tank is securely positioned and the hose is properly connected before opening the valve. Always wear gloves and eye protection when emptying your waste tank.
Q: How often should I empty my portable waste tank?
A: Empty your tank before it gets too full. A good rule of thumb is to empty it when it’s about 3/4 full. This will prevent spills and make it easier to maneuver.
Q: Where can I dump my portable waste tank?
A: You can dump your portable waste tank at any RV dump station. These are typically located at campgrounds, RV parks, and some gas stations. Never dump your waste tank in unauthorized areas, as this can contaminate the environment.
Conclusion
Choosing the right portable RV waste tank can make your camping trips much more enjoyable. Consider your needs, budget, and camping style when making your decision.
