Helpful Hints
■
Empty the black water fi rst. Use gray water to rinse
the hose after emptying the black water.
■
Additional hoses can be purchased from Thetford and
used to extend the length of the evacuation hose.
Connect the hoses using 1.5 in. (3.8 cm) barbed
coupling with clamp.
■
If you wish to extend the discharge hose, connect a
0.75 in. (1.9 cm) inner diameter garden hose to the
end of the nozzle. Do not extend the hose beyond
150 ft. (45 m).
A longer discharge hose reduces fl ow rate.
