Sewer discharge upgrade 2010 Elkmont

[Wavery]

Pictures say a thousand words.

Before and after pics.

Take notice that my trailer has a 2 7/8" lift kit on it. If yours doesn't have the lift, your grey water discharge pipe will need to be routed under the axle. There's plenty of room and slope.

You just need 7' of 1.5" ABS pipe
1, 90* (sweep) fitting.
1, 45* fitting
1, small bottle of ABS cement.
1, Double gate valve.
1-2 hours of free time.

Here is the double valve that I used:

If yours doesn't have the lift, your grey water discharge pipe will need to be routed under the axle.

Good pic, I like what you have done. But a quick question. If the gray-water drain pipe had to drop down under the axle, and then rise again to connect into the combined drain assembly, doesn't the low point under the axle form a crud-catching trap in the drain pipe? Or is there a way to rotate the fittings to avoid that?

Or maybe the "whoosh" when you open the dump valve is enough to clean it out every time?

It doesn't really effect the slope of the pipe. It just changes the location of the axle. The axle will simply be higher without the lift kit.

In this picture, the axle would fit nicely in that space above the drain pipe. There is about 4" between the frame and the pipe.
