Finally, the system, including the tank, should be at least nominally rinsed after each pump-out, through the head or through a deck Rinse-Out fitting with fresh water only. (If your marina does not have a dock water hose for this purpose, ask them to install one. It should be separate from the potable water hose, and the two hoses should never be interchanged.)

The rinse-out fitting supplied by Tek-Tanks is used with a 3/4″ bore sanitation hose.
