Yes John, you are probably right in the scenarios you have experienced. I however want to dump into an outdoor municipal sewer that is presently not conveniently close to the drive. Not all want to pump into a septic tank.
Without having tried it yet, I don't hesitate to say I don't anticipate it being any more unsanitary than the large gravity dump method.
I do value your opinion and will be on guard.
The cleaning of the drain hose seems to be the problem to me. I will not be connecting it directly to any potable water supply.
What do you think of those long gravity hoses that sit on little stands to keep it all going down hill? Now that's something I don't like!
