Your cart is empty.The Camco 4-in-1 Sewer Extension is ideal for reaching recessed dump stations to keep everything flowing smoothly. By elevating the sewer elbow out of a recessed sewer inlet, the 4-in-1 Sewer Extension streamlines the hose, reducing unwanted kinks and bends. The 4-in-1 Sewer Extension fits between the 4-in-1 Adapter and the elbow and extends adapter 3". Sewer Extension is clear, allowing you to see when the tank is empty. It locks securely to help prevent spills, and is compatible with any Camco 4-in-1 Adapter.

Saw this item on an influencer video. Purchased it and ended up using it the next time we went out. Worked great and helped to ensure a tight fit. A little difficult to remove. Would be nice to have a table on it to grab.

Product works well when rv sewer hook up is to low in the ground for the standard elbow to hook to.It locks on with a twist and no leakage.

I have been to several campgrounds that had their sewer hook up in concrete below grade. With this extension you can hook your hose up with every thing attached as it should be.

I should have checked. Like another reviewer said, it is not as long as it looks.

I’ve been RVing for many years and was often annoyed when parks would have sewer hookups that were sunk into a concrete basin. This solved the problem of not having an air-tight connection.

Very helpful to add hight for clearance! So I can screw on the elbow. I added it between the sewer threaded piece and the elbow

Perfect for my needs! Solidly made, easy to attach/detach and seals well in my 4-in-1 elbow.I recently stayed at a campground where the sewer pipe was set flush in a small depression in a concrete pad. I couldn't get the elbow screwed in to the end of the pipe properly because the the horizontal part of the elbow rubbed on the surrounding concrete. With this extension in place I was able to attach the elbow securely and not worry about grey and black water spilling all over the place.

Haven’t used it yet but will come in handy when you get those sewer connections that are sunk into the dirt or concrete.
