Section 8: Plumbing System
Black /Gray Tank Drains and Macerator System
Depending on your model, the gray tank drain and black tank drain (also referred to as dump
valves) may be located in the exterior utility center. These valves may have either an electric
switch control and/or a manual handle.
Always drain the black water holding tank first so the following wastewater can help rinse
any solids or debris from the dump outlet and sewer hose.
Macerator Pump System
Your motor home is equipped with a macerator pump system used to discharge waste from
the gray and black waste tank. The system has a 1-1/2-inch diameter flexible hose that runs
from the pump and attaches to a separate compartment on the exterior of the motor home.
Not all models are equipped with an external storage compartment. The system when pow-
ered on can discharge waste (uphill if necessary) up to a distance of 150 feet.
Open the hose compartment and pull out the 1-1/2 inch flexible
hose with the attached dump connector. The dump connector in-
cludes two connections: a small removable cap for attaching a
3/4 inch garden hose, or a larger 3-inch removable cap which
allows it to be attached to the sewer outlet at the dump station.
Using the macerator system
1.
To make drainage easier, level the motor home.
2.
Attach the dump connector to the 3-inch sewer outlet at the
dump station, or to a 3/4-inch garden hose and run the hose
to a dumping location.
Before operating the macerator pump, make sure the external dump hose is
properly attached at the motor home and at the dump station. The hose is
under pressure and therefore waste is discharged under pressure.
Failure to
follow instructions can lead to possible injury or property damage. The
use of this system for anything other than intended will void the warranty.
Water can accumulate in the flexible hose and dump connector of the macera
-
tor system. When winterizing the RV, antifreeze must be added to the macera-
tor system. Refer to the
Winterizing
section.
Before using the recreation vehicle, or after dumping the grey and black water holding tanks,
always add the proper amount of deodorant to the black water tank to prevent odors and
help break down holding tank contents (unless winterizing). Follow the deodorant bottle or
package instructions. Driving to a disposal site will normally loosen any accumulated waste
debris or solids from the sides of the holding tanks.
Never travel with full black or grey water holding tanks. Depending on the
location of the tank(s) it can affect your tow vehicle handling characteristics.
