Yes, we've had trouble with them. Usually a vacuum leak causing it to not keep pressure but with a few replacement parts kept on hand it is repaired. Never something that had to be done to make it function. The good part of the Vacufush is the low water volume used making the holding tank take much longer to fill. Using fresh water is also a plus smell wise.

Although I bitch at the Vacuflush once in a while, it's never failed us (As long as we have some duck bills and seals on hand for maintenance. Easy to replace.)

In looking at the Raritan I was wondering if the head had to be removed in order to get to the parts to repair it. The Vacuflush, having the vacuum mechanism separate might make it easier to maintain.

Peggy, without giving consideration to $$$, between the two, what's your thoughts?
