CHAPTER 4
THE SYSTEMS
PLUMBING SYSTEM
Included in your Jayco recreation vehicle is a complete fresh water system. Fresh water
may be obtained through two sources: city water connection or gravity fill tank. Each
component is explained along with its operation.

City Water Connection
Water may be received into the system through a direct hookup referred to as the city
water connection. (Fig. 4-2 or 4-3) After hooking up water hose to travel 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.
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 travel 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. 4-1 is the type found on most
models. Fig. 4-2 has a combination of gravity fill and city water connection enclosed
which requires a key to gain access.
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.
