BLACK WATER TANK
Holds the drainage from what is flushed down the toilet (
RM model also houses the sink water
). This tank needs much
more attention than the Grey water tank. Your coach will have a black tank wash fitting on the liquids control board.
Connect a freshwater hose to this fitting and flush any loose debris remaining in the tank after the tank has been emptied
and the drain hose is still in the dump. This black tank wash is designed to spray most areas inside your tank. Although
the primary concern with the black water tank is controlling odor, you must also keep solid waste and toilet paper from
collecting and plugging the drain line and valve.
TANK WASH CONNECTION
When using a sewer hookup at a campsite, do not leave the dump valves open. If you leave the valve open, it
does not allow any fluid to be stored in the holding tanks, and a good supply of fluid is necessary to adequately
flush the black water tank. It is best to wait until the black-water tank is around 3/4 full before dumping.
DUMPING THE WASTE-WATER TANKS
Holding tanks are enclosed sewer systems and as such must be drained in an approved dump station.
Both toilet and gray water holding tanks must be drained and thoroughly rinsed regularly to prevent accumulation
of harmful or toxic materials.
Capacity could vary on each trip due to the number of people using the system.
Under no circumstances should the contents of these tanks ever be emptied beside the
roadway, in a river or stream, or directly upon the ground. It is illegal and is in violation of
all sanitary practices.
It is up to the camper to make sure that his camping site is always left in a clean and
sanitary condition. Each person should police his own area before leaving
.
HOW TO DUMP
Basically, both holding tanks empty the same way, through a single outlet located on the underside of your
unit, but each tank is controlled by an individual slide drain valve. (Check your floor plan and specifications for
location.)
1
Level the vehicle or slope toward the termination outlet.
2
Remove the sewage drain hose from its storage under the unit (see picture).
3
Check to make sure both dump valve slide handles are fully
closed.
4
Remove termination outlet cap and connect the sewer hose.
5
Place the other end of the hose to the dump station inlet.
6
Pull the slide drain valve on the black water tank and drain until
empty.
7
Pull the slide drain valve for the grey water tank and drain until
empty. This allows the grey water to flush any leftover blank tank
waste out of the drain line.
8
Close both dump valves when the tanks are empty.
9
Attach the freshwater hose to the black tank spray and allow it to
spray for approximately 2 minutes.
10
Open black water tank valve again to flush and drain.
