Macerator Bypass Valve:
There is a macerator bypass valve located in the utility center
in the event of a malfunction with the macerator pump. This
bypass will gravity dump the waste from the tanks straight
down to a 3 inch sewer hose connection under the motor home.
To operate:
1. Attach a 3 inch sewer hose to the connection under the
motor home, and to a sewer outlet at a dump station.
2. Open the desired black / gray (electric or manual) drain
valves, one at a time.
3. Pull the manual macerator bypass valve to open and the tanks will empty by gravity.
4. When nished, close the macerator bypass valve, the black / gray dump valves, and
disconnect the sewer hose from under the motor home and at the dump station.
The black tank ush can also be used with this bypass.

The black tank ush is also called a “no fuss ush.” The black tank ush inlet is located on
the utility center panel. Attach a garden hose (connected to a pressurized fresh water source)
to the black tank ush inlet. The water goes directly into the black water holding tank where
there is a “sprayer” connection. This allows you to rinse the black water holding tank by
removing debris and preventing accumulation. There is a check valve incorporated in the
plumbing lines to prevent back ow.
Flush the black water tank each time the grey and black water holding tanks are dumped or
as needed: (Refer to Macerator Pump System section)
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 ush.”
3. With the water source turned ON, ush the black water
holding tank until the water running out of the black
tank drain valve is clear (not discolored or cloudy).
