A Guide to Selecting the Best Rv Sewer Tank
Choosing the right RV sewer tank is essential for a comfortable and hassle-free camping experience. The sewer tank, also known as a holding tank or portable waste tank, is responsible for storing wastewater from your RV until it can be properly disposed of. When selecting a sewer tank, it's important to consider your travel habits, the size of your RV, and how often you'll have access to dump stations. Understanding the key features will help you pick a tank that fits your needs and makes waste management as easy as possible.
Tank Capacity
Tank capacity refers to how much wastewater the tank can hold, usually measured in gallons. This is important because it determines how long you can go between emptying the tank. Smaller tanks (10-15 gallons) are lighter and easier to transport but need to be emptied more often, making them suitable for solo travelers or short trips. Medium tanks (16-25 gallons) offer a balance between portability and capacity, ideal for couples or small families. Larger tanks (26 gallons and above) can handle more waste and are better for bigger groups or longer stays, but they are heavier and may be harder to move. To pick the right size, consider the number of people using the RV and how frequently you plan to empty the tank.
Portability and Design
Portability and design refer to how easy it is to move and use the tank. Some tanks come with wheels and handles, making them easier to transport to a dump station, while others are more basic and may require lifting. If you expect to move the tank by hand over longer distances, look for models with sturdy wheels and comfortable handles. If you’ll mostly be stationary or have easy access to a dump station, portability may be less important. Your physical strength and the terrain where you’ll use the tank should guide your choice.
Material and Durability
Material and durability describe what the tank is made of and how well it stands up to regular use. Most RV sewer tanks are made from heavy-duty plastic, which is resistant to chemicals and impacts. Thicker, high-quality plastic will last longer and be less likely to crack or leak. If you plan to use the tank frequently or in rough conditions, prioritize durability. For occasional use, a lighter or less rugged tank may be sufficient.
Ease of Emptying and Cleaning
Ease of emptying and cleaning is about how simple it is to drain and rinse out the tank. Features like large, well-placed drain openings, integrated rinse ports, and clear hoses can make the process much easier and less messy. If you want to minimize contact with waste and speed up the cleaning process, look for tanks with these user-friendly features. If you don’t mind a bit more effort, a simpler design may be acceptable.
Compatibility with RV Connections
Compatibility with RV connections means making sure the tank’s fittings and hoses match your RV’s waste outlet. Most tanks use standard fittings, but it’s important to check that the tank will connect securely to your RV. If you have a unique setup or want to use the tank with multiple RVs, look for models with adaptable or universal fittings. Ensuring compatibility will prevent leaks and make the dumping process smoother.
Storage and Size
Storage and size refer to how much space the tank takes up when not in use. Some tanks are designed to be compact or have features that make them easier to store, such as stackable shapes or removable parts. If you have limited storage space in your RV or tow vehicle, consider a tank that is easy to stow away. If space isn’t an issue, you can focus more on capacity and other features.
