Section 8: Plumbing System
Black Tank Flush
The black tank flush (no fuss flush) inlet is typically located on the utility center panel (if so
equipped) labeled as “Tank Flush”. For models not equipped with a utility center, the inlet
is located on the side of the recreation vehicle. The location may vary depending on your
model. Attach a garden hose (connected to a pressurized fresh water source) to the black
tank flush inlet. The water goes directly into the black water holding tank sprayer connec
-
tion, allowing you to remove debris and preventing accumulation. A check valve is incor-
porated in the plumbing lines to prevent back flow. Flush the black water tank each time the
grey and black water holding tanks are dumped or as needed.
NOTE: Utility center (if so equipped) valve positions do not affect the tank
flush function. It does not matter where they are positioned when operating
the tank flush.
NOTE: To help insure debris does not clog the tank sprayer orifices, use
“TANK FLUSH” every time the waste holding tank is emptied.
1.
Dump the black water tank (see Gray Tank Drain & Black Tank Drain) and leave the
black tank drain valve open.
2.
Connect a garden hose from the water supply source to the black tank flush.
3.
With the water source turned ON, flush the black water holding tank until the water
running out of the black tank drain valve is clear (not discolored or cloudy).
4.
Disconnect the garden hose and close the black tank drain valve. Fasten the sewer hose
housing dust cap back on the tank flush inlet.
The black tank drain valve must be OPEN any time there is a hose (water
supply) connected to the black tank flush.
Do not leave any hose (water supply) connected to the black tank flush
when it is not in use.
Do not use the same hose to fill your fresh (potable) water tank that is used for
the black tank flush.
Macerator Emergency Cutoff
The macerator system includes an emergency cutoff valve that stops
the flow of waste through the flexible 1-1/2-inch macerator hose. The
valve is at the back of the utility center
(Fig A).
The handle for the
cutoff should be pulled UP for NORMAL operation. To engage the
cutoff, push the valve handle DOWN
.
Refer to the macerator manufacturer’s owner manual included in
your warranty packet, for additional information on operation, safety,
troubleshooting and winterizing. Contact your RV dealer for assis-
tance in the purchase and installation of a sewer hose and/or sewer
hose extension (if needed).
