PLUMBING SYSTEM

Included in your Jayco park trailer is a complete fresh water system. Fresh water may be obtained
through two sources: city water connection or an optional gravity fill tank. Each component is
explained along with its operation.

City Water Connection

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 (Option)

A water tank may be permanently installed in your park trailer. On
some models it is located inside the park 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. 4-2 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.

CAUTION: DO NOT leave tank unattended while filling.

THE SYSTEMS
Water may be received into the system through a direct hookup
referred to as the city water connection. (Fig. 4-1) After hooking up
water hose to park trailer, open valve on supply line. Enter coach
and open faucets to bleed air from lines. Water will fill water heater
first before supplying lines and faucets. When lines are almost full,
you may experience some air pockets. Allow them to escape before
closing faucets.
