"Pcurt"......is right on the money. I've had two SaniCon units. One came with my 2005 Diplomat as standard equipment. I ordered a second one before I even took delivery of my Newmar.
In both cases, I found that the box that SaniCon uses is bulky and restricts the direction or placement of the unit in your water bay. When I received the new one for my Newmar, I tossed the outer box and was able to mount the Flojet pump exactly where I wanted it and in the direction I wanted the hoses to go....couldn't do that with the supplied box/cover. The cover is really more for aesthetics.
Now I'm just the opposite from "Pcurt" when it comes to the hose. I like the flexible one sold with the SaniCon unit. After I dump, I put the cap on the hose and it easily coils up on the floor of my wet bay. The grey water bypass is a must!
In this photo you can see how easy it is to just let the coiled hose lay on the floor of the wet bay. The hose is sealed with a screw on cap, so no leaks.
