The Sani-Con is a macerator pump that literally “grinds” the sewage and pumps it out of your holding tanks. It is not a gravity-based system as are normal sewer hoses. The Sani-Con works very much like a household garbage disposal as it grinds solids into tiny pieces that will pass through the pump.
This small pump is mounted in your sewer compartment with a short, sturdy hose for connecting it to the 3-inch termination point (what you call the “sewer-hose hookup” on your coach). The Sani-Con connector hose looks like a normal sewer hose but it is heavy, black, and much more rigid than the “normal” sewer hose that’s been around for years—the one affectionately known as the “Stinky Slinky.”
The output of the pump is through an extra-heavy duty 1-inch diameter discharge hose that is permanently clamped to the pump output. This hose stores in a small area—usually lying on the floor of the utility compartment—and stretches to approximately 20 feet. It has a permanently attached discharge “end”—an easy-to-use threaded nozzle that is designed with various threads and sizes to adapt to most sewer hose connections in the ground (including friction-fit) at campsites or dump stations. When dumping is complete, a garden-hose cap is screwed onto the discharge end to close the hose for storage. Doing this, the system becomes sealed and nothing leaks.
Dumping with the Sani-Con is cleaner (by far) than with traditional sewer hoses and it’s easier to get out and put away. You can completely dump grey and black tanks without spilling a single drop!
You have nearly unlimited access to dumping. Using a 3/4-inch garden hose as an extension, you can pump 300 lineal feet with a 20-foot rise. This means you can pump uphill into a backyard sewer cleanout, into a household toilet on the second floor, or into an elevated sewer dump station.
[Author Note: Purchase an inexpensive “Contractor’s” 3/4-inch garden hose at any major building supply. Check the inside diameter of the brass hose-connection on each end carefully. Many will have 5/8-inch or even 1/2-inch brass hose connectors on the 3/4-inch garden hose! I have no idea why this is.
Do not use this hose as manufactured but replace the original smaller connections with real 3/4-inch connections (must have a 3/4-inch opening inside the brass fitting). Only then is it ready to use with the SaniCon. This is an inexpensive replacement and the contractor hose is cheap, too.
The reason for this is that the smaller diameter will cause backpressure on the Sani-Con pump and could burn it out. A hose with the full 3/4-inch connection will work just fine.]
I purchased one Contractor hose that was 75’ long, cut it into thirds, and made up three 25-foot hoses for dumping only. Along with the 20-foot-long discharge hose (attached to the pump), I can dump about 100’ away.
The Sani-Con is a good, clean, efficient, well-designed system. I recommend it and have used one on my last two coaches. We have never had to use a traditional sewer hose on our current coach.
