CITY WATER HOOK-UP
The city water hook-up is found in the underbelly untility compartment on the trailer. A
short piece of hose has been provided to extend the city water hookup.
Use a high-pressure hose of at least 1/2” diameter. It should be one that is tasteless,
odorless and non-toxic designed for RV use. The city water inlet is a standard garden
hose thread. We suggest you carry two lengths of hose. This way you have the ability
to reach hookups further away than normal, plus you have a spare hose should one fail
or become damaged unexpectedly.
After hooking up the hose and turning on the city water valve provided in the park,
slowly open a faucet. There will be a lot of spurts and sputtering until all the air is
expelled from the trailer system. If the water heater is empty it will take some time
before all the air is expelled and you get a steady flow of water at the faucet. Once
a steady flow is achieved at one faucet the others should be opened long enough to
expel the air in the lines going to them.
Water pressure at some campgrounds may be low. The water pump can be turned
on to assist the city water hookup pressure. Be sure there is some water in the fresh
water tank. The pump will only use the water that is needed out of the tank to bring the
pressure up to the usual standard.
Your plumbing system has a built in pressure regulator to protect your lines and faucets
from extremely high pressures on some city water systems.
EXTERIOR WATER SERVICE
Also in the underbelly utility compartment is a hose connection for the exterior water
service. This is plumbed into the high-pressure water system of the trailer. This is
an ideal place to rinse the sand off your feet after going to the beach, cleaning mud
off your boots, and hundreds of other messy jobs that are better done outside. On
all units except the 27’ and 25’ Front bed Model an exterior water service shut off
valve is located nside the lavatory cabinet and can be accessed by either opening the
cabinet doors or removing the cabinet drawers. The front bed models shut off valve is
accessed by removing a door on the wardrobe bottom shelf. The exterior water service
is located beyond the heated area of the trailer and can be damaged if the water is
not turned off in freezing temperatures. In freezing temperatures close the shut off the
valve and open the exterior water service valve to drain the valve and line.
NOTE: On some units only the exterior water service shut off valve will be located
inside the lavatory cabinet. On others there may be up to five valves located inside the
cabinet. Three of these are used as the water heater by-pass system as described in
the winterizing section. Another may be for the toilet shut off. The fifth valve is for the
exterior water service. Always check to see if the water supply has been cut to the
exterior service before using the rest of the water system in freezing weather.
