PLUMBING SYSTEM
Included in your Jayco recreation vehicle is a complete fresh water system. 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. 4-1).
The water pump and valve connections, are typically located under the bathroom
vanity and/or the dinette seat.
NOTE: The pictures for the following instructions show the layout of the
valves, not their locations in the vehicle.
• Connect a garden hose from the water
supply line to the "city water connection".
(Fig. 4-1)
• Make sure that valves 1, 2, 3, 5, and 6 are
closed and valve 4 is open. (Fig. 4-2 & 4-3)
• Open the valve on the water supply line.
• Enter the unit and open the faucets to bleed
air from the lines. The water heater will
fill first, followed by the supply lines and
faucets. When the lines are near full, you
may experience come air pockets. Allow
them to escape before closing the faucets.
• Close valve 4. (Fig. 4-2)
#
CAUTION: Excessive pressure from water supply 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.
