It takes more than a hose to get your sewage where you want it to go. The angle from your sewage tank to the connection at the campground must be proper. That is why Camping World carries a number of solutions for just such a situation.
First, make sure you know how to connect your hose to the outlet at your tank; errors here can create a big problem. Use the right clamps and you are half way there. Next, direct your sewer hose from the tank to the connection offered by the campground. To maintain your angle, use one of the many tools we carry. They are all designed to provide downward momentum for any material entering your hose.
