Black Tank - Regency ULTRA Owner's Manual

WATER AND PLUMBING OPERATION
Black Water – Waste Holding Tank
The black water holding tank collects all the waste
from the toilet and bathroom sink. Before using your
waste holding tank, deodorize it by adding one gallon
of water and a commercial holding tank deodorizer
into the toilet.
To display the black water holding tank level, depress
and hold the black water tank level switch to show
the percent-full level on the LED display.
NOTICE
Overfilling the black water holding tank could
cause the overflow to back up through the toilet.
Dumping Holding Tanks
o Connect the sewer hose to the tank outlet
located on the rear driver's side underbody.
The sewer hose is stored on the driver's side
under the floor as shown in (island and twin
bed floor plans) or below the slide out.
o Pull the black water tank dump valve handle
first, then pull the grey water tank dump
valve handle. Push in the handles when you
no longer hear or feel waste water flowing
through the sewer hose.
Black Water Waste Tank Rinse
The motorhome is equipped with a black water
waste tank flushing system to improve draining and
to reduce odor. To flush the tank, follow these steps:
o Remove the protective cap and connect the
city water supply hose to the connector
located in the exterior utility center.
o Open the black water tank dump valve.

NOTICE
Always open the black water tank dump valve
before turning on the water supply.
o Turn on the city water supply to thoroughly
flush the system.
o Turn off the city water supply, disconnect the
city water supply hose and install the
protective cap on the connector.
o Close the black water tank dump valve.
NOTICE
The black water tank flush line incorporates a
non-return valve which prevents blackwater
contamination of the city water supply hose. If
city water does not flow when connected as
above, the non-return valve may be defective
and require replacement. The non-return valve is
located behind various wall panels depending on
coach floor.
