Like "Trout" I also have a Sewer Solution. I've not yet been slapped for the water usage but can see the argument. That issue aside, I think it's the stuff. Have used mine for about 2 years and have had no problems at all. It comes with a 10' section and I had to get an additional 10' to make the longer runs to sewer hook-ups. It seems to rinse out really well. While in storage I keep it in a clear plastic box and leave the lid off so it will dry out completely and have never had a problem with a smell from it. When we bought our TT the dealer gave us the "starter" kit which included a low end slinky. I keep it in the rear bumper as a backup.
