EXTERNAL WATER
SUPPLY (“City Water”)
To Connect to an External Source:
1. Turn the demand pump switch to off.
2. Attach a hose from the external water source
to the city water connection in the utility
compartment or on the left side of your
vehicle.
3. Turn on the external water source.
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 - Optional
The exterior 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. A water pump switch is locat-
ed near the shower faucet for your convenience.
City Water Connection
If items are placed into the shower
tub before shower valve vacuum
release is complete, they may become
wet.
