I don't have any experience with the Sani-Con system but looking at the Thetford web site I'm not sure if you can use anything other than the affixed hose.
I use a FloJet system that will use a standard garden hose or a hose similar to the one on the Sani-Con.
While I have not pumped 180 feet I have gone over 100 feet.
Here is a link to some info from Camping World. [
