USING ON-SITE SEWER HOOK-UPS
When staying at a campsite where sewer hook-up is
available, the sewer hose may be attached and left
in place for the duration of the stay�
Do NOT leave the dump valves open. Open the
dump valves only when the tanks are full, or when
you are ready to leave the campsite. This will keep
solid wastes in suspension allowing them to drain
with the liquids when you open the valves. If the
valves are left open, the liquid waste will drain,
leaving the solids to collect on the oor of the black
water holding tank. If solids collect, close the valves,
ll the tank with water and drive a few miles. You can
also help clean the tank by adding 1/4 cup of dish
detergent to the water. The motion of the vehicle and
the water will help dislodge the wastes and allow the
tank to drain in the usual manner.
