ING SYSTEMS
When connected to an outside source of
water, the water bypasses the demand pump and
storage tank and supplies pressure directly to
individual faucets and toilet. A check valve built
into the pump prevents water from entering the
pump and filling the storage tank.
NOTE: Because city water pressure varies from
location to location, we recommend
using an
in-line water pressure regula-
tor
to prevent damage to any compo-
nents, connections and seals in your
fresh water system.
A water pressure regulator may be
obtained from any well stocked RV
dealership retail center and some retail
discount centers. These devices simply
connect in-line between the supply hose
and the city water input on the coach.
We recommend a regulator that controls
water pressure to
40 psi maximum
.
To disconnect from the external source:
1. Turn the external source off.
2. Open a faucet inside the vehicle to relieve
line pressure.
3. Disconnect the hose from the vehicle and
replace the cap on the connection.
SHOWER HOSE VACUUM
BREAKER
After using the shower, you may notice water
dripping from the shower faucet assembly. The
dripping results when vacuum in the shower hose
(after closing the shower faucet) slowly releases
and allows water remaining in the hose to drain
down. This is a normal function of the shower
valve assembly and is not a leak or defect.
The International Association of Plumbing
and Mechanical Officials Standard TSC 21-85
(PAR. 4.3) states:
“Shower heads which incorporate shutoff
valves, shall have a minimum “drip rate” of one
(1) quart in thirty (30) minutes.”
EXTERIOR SHOWER/
WASH STATION
The exterior shower/wash station feature
allows you to do things such as rinse off sand or
salt after a swim, rinse off muddy boots, or bathe
your pet outside the coach.
The shower is located in the service center
compartment on the left side of the coach, just
ahead of the rear wheels.
TOILET
The toilet in your motor home is very similar
to the household type, except that it is designed to
use only a small amount of water per flush. It
uses a high velocity jet of water, producing a
swirl effect, to efficiently cleanse the bowl.
City Water
Connection
If items are placed into the shower
tub before shower valve vacuum
release is complete, they may become
wet.
