A belated Welcome april fool to the Newmar forum and irv2.
I have not as yet, on my coach the compartment is small where the dump discharge is and it can not be mounted dirrectly to the pipe.
Will use a short piece of hose and mount to side wall after I move light fixture.
You may have a large dumping area and different pipe arrangement and able to connect directly to discharge pipe.
Here are a few systems that you can use for your configuation. Macerator Pump Sys
Enjoy the forum and do post often.
