WATER SYSTEMS - INTRODUCTION
This section contains information about the
operation and care of the various water system
equipment found in the motorhome. Optional
water equipment will also be discussed, so
not all information may be applicable to the
motorhome. More detailed information with
CAUTION or WARNING instructions for
various equipment, other than what is found in
this section, can be found in the OEM manuals
in the owner information box.
Newcomers to a self-contained motorhome
soon discover water does not last long unless
consumption is drastically reduced. For
example: less water can be used for showering
if the shower is turned off while soaping down
and then turned back on to rinse. In this way a
shower uses two gallons of water or less. There
is plenty of water to meet personal needs once
habits are adjusted.
The motorhome plumbing system may be
operated with or without shore services. The
plumbing system holding tanks include a fresh
water tank, a grey water tank and a black water
tank. An onboard water pump will supply all
faucets and toilets with water from the fresh
tank. The sinks and shower drain into the
grey tank, and the toilet drains into the black
tank. Close monitoring of the holding tanks is
necessary when shore services are not available.
There are two monitor panels – one in the
hallway and one in the service bay.
The motorhome plumbing system can be
attached to shore services (city water and sewer)
at the roadside service center. The service center
includes the city water/fresh tank ll connection
and the grey and black tank valves, drains and
tank ush connections. If shore services are
available, the shore water supply (city water)
can be used to pressurize the water system so the
onboard water pump can be left off.
The grey and black tanks share a termination
outlet. A sewer hose can be attached from the
termination outlet to the shore sewer connection.
Leave the black tank drain closed and the grey
tank drain open when hooked to shore services
to avoid a clogged sewer hose. Drain and ush
the grey and black tanks after dumping and/or
prior to departure.
Fresh Water System:
The fresh water system consists of the fresh
water tank, water pump, water lter and a water
hose for potable water use only. Proper care
of the hose is necessary. After each use, drain
the water hose and attach the plug to keep out
insects and debris.
Waste Water System:
The waste water system consists of a waste
holding tank (grey water), a sewage holding tank
(black water), ush system, toilet and drains.
WARNING:
Water is electrically conductive. DO
NOT use any electrically powered item
or electrical outlet that may be exposed
to a water source. Such use can result in
a serious shock, causing injury or death.
