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.
