supplying lines and faucets. When lines are almost full, you may experience some air pockets.
Allow them to escape before closing faucets.

CAUTION: Excessive pressure from water supply systems may be encountered in some
parks, especially in mountain regions. Water pressure regulators are available to protect your
system against such high pressure. A regulator of this type is recommended to prevent
damage to plumbing systems or components. Not using a water pressure regulator when
using city water may cause the o-rings to blow. It is advisable to always use a water pressure
regulator when using the city water connection.

Water Tank - Gravity Fill

A water container is permanently installed in your recreation vehicle. On some models it is located
inside the sport utility trailer under a bed, dinette, or sofa. Other models may have an external tank
under the floor between frame members. To fill the tank, there are two types of gravity fill
connections to the fresh water tank. Fig. 4-1B is the type found on most models.
The fresh water tank can be filled by removing the gravity fill cap and inserting a garden hose. Open
faucet from water supply and fill tank. You must be careful not to over fill tank. This can pressurize
the tank, causing leakage and water damage.
I
CAUTION: DO NOT leave tank unattended while filling.
