Water Pump
The RV water pump is a 12-volt DC appliance that is
activated by a switch in the kitchen area or on the
monitor panel. The switch may be left ON while
camping. This is called a demand system. (FIG. 14)
(FIG. 14) WATER PUMP
Turn the faucet on when you want water. The pump
will run only as long as needed. If the pump fails when
the switch is ON, check the fuse located in the
converter. If the pump continues to operate whether
the faucet is open or closed, check the water tank to
see if it is empty and check to see if there is a leak in
the system.
DO NOT RUN THE WATER PUMP WITHOUT
WATER IN THE SYSTEM. ALWAYS KEEP THE
PUMP SWITCH OFF WHEN THE SYSTEM IS EMPTY
OR WHEN CONNECTED TO CITY WATER.
RUNNING THE PUMP DRY CAN DAMAGE IT AND
VOID THE WARRANTY.
Secondary water pump switch
Some vehicle models have a second water pump
switch located in the bathroom near the lav sink. This
switch will turn on the water pump whether the main
water pump switch is on or off.
Winterizing the Water Pump
With the water drained from the potable water tank,
disconnect the water pump outlet hose and then turn
the pump on to allow the remaining water to be
pumped out (less than one cup).
If you desire, you can blow out the water lines with
compressed air by opening al valves and placing the
air nozzle into the system where the outlet hose has
disconnected. Replace pump hose.
Water manifold system (USA only)
The water manifold system directs a separate hot
and cold water line to each fixture in the RV.
Therefore, if you wish to change your kitchen sink
faucet, you need only to shut off the supply lines
labeled “Kitchen sink.” This will allow water supply to
all other fixtures during service or replacement.
The water manifold is located in an exterior
compartment. To activate water on a specific valve,
use the provided key and turn the lever until it is lined
up with the indicated arrows (left/right). To shut off
water supply to a specific line, turn the key ¼ turn in
either direction (up/down). Note that both the hot and
cold lines must be turned off for removal of plumbing
fixtures.
Winterizing bypass on water manifold
The water manifold is designed to also act as a
bypass for the water heater when winterizing the
coach. To bypass the water heater, turn the cold #9
valve off, and the hot #9 valve on.
Drainage and Sewer
Your RV has a Drainage/Sewer system that operates
much the same way as the one in your home. How
extensive the system depends on your unit model and
the options you obtained. It includes a drain line from
the kitchen sink and shower to a GRAY WATER
HOLDING TANK. There is also a marine toilet and
lavatory that empties into a separate BLACK WATER
HOLDING TANK. Which tank each sink drains into
may vary from one model to another.
The drainage system also includes vents that carry
odors caused by drain water and waste out of the RV,
while also equalizing air pressure. Drain clean outs
are provided to clean lines between fixtures and
holding tanks.
Drainage P-traps
By code, all drains are equipped with P-traps to keep
holding tank odors from entering the vehicle. If you
detect a foul odor, which you believe is from your
holding tanks, add water to all drains to ensure that
your P-traps water hasn’t evaporated from long term
storage. Places to add water include the Kitchen sink,
Bathroom sink, shower/tub, wet bar sink, and the
washer/dryer drain.
