turbojimmy,
Glad to hear that the SS worked for you. I really wasn't sure if it would or not. I use one and at the house it has to push the stuff about 60' and up about a foot. It works fine with my Class A, but my brother-in-laws TT wouldn't work because his black tank was nearer the ground (probably by 1-2 ft. lower than in our Class A) and the water couldn't push the stuff without that extra "potential energy" it has with the higher black tank. Kind of an interesting hydraulic problem, I guess. :)
I would make one suggestion. Are the push-on connections you made glued together? If not, they should be, and I would extend your connections a bit to include a shut-off valve before the hose goes into the sewer connection. That's what I did with mine. (I built my connection from the sewer clean-out fitting on the basement floor.) On my setup, all of the fittings up to the shut-off valve are all glued. IF the sewer should ever back up (very unlikely, but not unheard of), it won't "push out" the SS connection and dump the sewage into our basement 'cause the valve is closed. It is one extra step each time when I dump to make sure the valve is open, but it's not a big deal. (On a more paranoid note, it also keeps anyone from trying to dump anything else into our sewer connection such as used motor oil, hazardous waste, etc. Yeah...maybe a bit far fetched...but better safe than sorry. The fines for dumping such things down your sewer can be pretty steep, or so I hear.)
One other thing you might consider is to get an estimate to have someone bore a 1.25" or 1.5" hole through your wall. It might not be that expensive, and then you'll be able to use the SS even if your water pressure drops because you won't have to force the water up as high. (Sometimes in our area, if people start watering their lawns, there is a noticeable drop in pressure.) Make a rigid connection right on the outside of the wall with a nice neat PVC pipe run to your present connection point.
Another benefit is I can fill the freshwater tank and/or use the black tank rinse while operating the SS and it still works with the reduced pressure.
It's easy to spend someone else's money! LOL :)
Anyway, good luck with the system. I love the SS. I use it almost exclusively now, even at campgrounds, unless they have a water shortage.
