Monarch SE 2004 - Waste Drain & Sewage Tanks; Drain Hose

The waste drain system provides adequate and safe storage and/or discharge of
waste materials. The drain system uses ABS plastic piping and fittings connected
to sinks, shower, toilet and holding tanks draining to an outside termination. The
motorhome should be reasonably level for optimum operation of the systems. The
wastewater holding system consists of a wastewater holding tank (grey tank). The
grey water tank stores the sink, shower and clothes washer drain water. A sewage
holding tank (black tank) stores waste from the toilet only.
Drain valves and a tank flush system dispose waste through a common termination.
Each holding tank has a separate drain valve dumping the waste water (grey
water) and sewage (black water) through a common single discharge outlet. The
tank drain valves are located service center on the roadside. Use the water monitor
panel to observe tank levels. When ready to drain the tanks, drain the sewage tank
first. Next, flush the black tank with the flush system. Close black tank valve after
flushing tank. Drain the grey water tank. Using this sequence helps flush solids
from the sewer hose. When traveling, it is recommend both holding tanks be
empty or less than half full.
A flexible three-inch sewer hose attaches between the
termination drain and the shore facility. The termination drain
by design is adjustable and should be exercised periodically.
Sewer hoses usually come in 10 or 20 foot lengths. The sewer
hose is stored in a tube accessed through a door on the
roadside next to the rear tire. The shore fitting for the sewer
hose may be three or four-inch pipe, which could be male or
female thread. Another possibility may be a four-inch pipe,
with no threads, covered by a metal plate. There are many
configurations. Different style adapters are available to fit
most configurations. Hose ladders may also be purchased to
support the hose.
It is important that the hose remains secure. Always tighten
clamps and restraining devices before use. Lay the hose
inline between the termination outlet and the shore fitting.
Restrain the hose to prevent movement during use. Wear
protective and/or disposable gloves when handling the sewer
hose.
To Exercise the Termination Drain:
• Grasp the drain firmly on both sides of the drainpipe.
• Swivel the pipe up and down several inches. This
exercises the internal O-rings.
• The drainpipe may be left in the upward position to
prevent any residual material from leaking out.
