We want to install a utility sink in the garage, but discovered that the slope/direction of the sewer main won't work for a gravity feed. They suggested a Saniflow pump, which would basically flush the wastewater upon each use like a mini pump station. It sounds perfectly reasonable. Aside from the added expense (about $800 installed), my main concern is the reliability. I can convince myself on the financial side, but not if it craps out every 3-5 years. Does anyone have any experience with one of these systems? Thanks!
