SECTION 10 – PLUMBING SYSTEMS
FRESH WATER SYSTEM
The fresh water system provides water to the
galley sink, shower, bathroom lavatory, toilet and
water heater. Water may be supplied by either of
two sources:
•
a water tank located within the motor home, or
•
any external water source to which the motor
home may be connected, known as "city
water".
Fresh Water Tank Filling
Procedures:
Always fill the fresh water tank at an approved
potable water filling facility or a known purified
drinking water source.
The tank may be filled either by gravity fill or
by pressure filling through the city water
connection. A special diverter valve will route
the water from the hose either directly to the
water lines for city water hookup use, or to the
fresh water tank for filling.
Gravity Fill:
Insert hose into fill opening and turn water
supply on. Tank is full when water flows from
tank vent tube beneath coach. The gravity fill
tube is located behind a small, lockable door on
the left (driver) sidewall toward the back of the
coach.
Water Tank Gravity Fill
To Pressure Fill Water Tank from City
Water Connection:
Attach hose to city water connector. Open tank
fill valve inside compartment, then turn water
supply on. Tank is full when water flows
from tank vent tube beneath coach.
NOTE:Always keep the tank fill valve in City
Fill position unless you are filling the
tank. If this valve is open while using the
city water, the water will keep flowing
into the tank and out the tank vent tube.
WATER PUMP
When your coach is not connected to a city
water supply, water is supplied from the fresh
water tank by a water system demand pump. A
demand pump is designed to run only when you
are using water. This is what happens when you
turn a faucet on - the water line pressure drops
and the pump begins to run, and it will continue
