248 | Section 6 Water Systems ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- ----------------- Monarch SE 2004
The grey water waste tank stores the sink, shower and clothes washer drain
water. No chemical is required in this holding tank; however, a waste holding tank
can produce odors. A reduced mixture of chemicals can help with odor control.
Ensure that there is enough liquid in the holding tanks prior to dumping the
waste holding tanks. This provides a smooth flow through the valve, drain pipe
and drain hose. When cycling the tank with sufficient liquid, a swirling action
should remove accumulated solid wastes along with the waste liquid. Empty the
sewage tank weekly to prevent stagnation and overfilling.
The motorhome comes equipped with a power flush system to aid in cleaning
the holding tank. The power flush nozzle, located in the black tank, helps reduce
solid build-up. Use the tank flush each drain cycle. Failure to thoroughly rinse the
tank each drain cycle may result in solids accumulating and a clogged spray
nozzle.
Dumping the Tanks:
1. When preparing to dump the black tank, first close the grey
water valve.
2. Fill the grey tank to at least 50% by running water in the
shower or sinks.
3. Use the monitor panel to observe tank fluid levels. When the
grey tank is 50% full stop filling the tank.
4. Open the black water valve. Allow the black tank to drain.
5. Use the tank flush system.
6. Connect a non-potable water hose, with pressure regulator, to
the flush system fitting located in the service center.
7. Turn on the faucet allowing water to rinse the black tank at
least three minutes. Never operate the system unattended.
Ensure the water flows freely though the drain hose.
8. When completed turn off the faucet and close the black water
valve.
9. Open the grey water valve. The water in the grey tank flushes
any remaining solids from the hose. With the grey water
valve open, run two gallons of water down any drain to flush
the grey tank. The grey valve remains open until the next
drain cycle or departure.
WARNING: Never operate the flush system unattended.
Flooding may occur. Use the tank flush system each time the
holding tanks are cycled. Failure to routinely use the flush
system will result in a clogged spray nozzle. Turn off the
water supply when finished flushing the tank.
