hose must be removed and the water filter
cartridge installed.
Replacing the water filter cartridge
Replace the water filter cartridge when water
flow from the kitchen faucet is too slow for
convenience, or at least once a year.
1. Drain the fresh water system.
2. Place a container beneath the water
cartridge filter to catch any spillage.
3. Unscrew the fittings at the top and bottom
of the water filter cartridge. Pull the water
filter cartridge down and out of the fittings.
4. Insert the new water filter cartridge and
tighten the fittings securely by hand.
Dispose of the used water cartridge filter.
For more information
Refer to the OEM operator’s manual and the
label on the water filter cartridge.
DRAINING THE FRESH WATER
SYSTEM
Permanent water tanks may be drained
through a valve located near the tank. A Jayco
RV with a demand pressure pump system will
have low-point drains attached to the water
lines (normally located near the water tank).
These low-point drains will release water in the
supply lines by opening the valves and all
faucets. The water heater has its own drain
plug. To drain the permanent fresh water
holding tank (if so equipped) and supply lines:
1. Open all faucets,
including the outside
shower faucet (if so
equipped).
2. Open the “exterior fresh
tank drain” valve on the
permanent fresh water
holding tank (if so
equipped). This knob
turns 45° to open or
close.
3. Open the “low point
drains.” These valves
are placed near the
floor and may be
located under
cabinets, dinettes,
sofas, or in storage
areas. As their name
indicates, they will be
at the lowest point of water lines. A label
may be placed on the outside of the RV to
indicate where the drains are located. The
drains will typically need to be opened from
inside the trailer. Once the label is found on
the outside of the trailer, go inside to find
the corresponding location of the drains.
4. Turn ON the water pump and allow it to run
as needed.
5. If so equipped, operate the toilet flush lever
until water stops flowing.
6. Open all faucets, including the outside
shower faucet (if so equipped).
7. Relieve the water pressure using the P&T
valve BEFORE removing the water heater
drain plug. Otherwise, if there is any water
pressure present the water will spray out of
the opening when the drain plug is
removed.
When you are finished draining the fresh water
system, reverse these steps and, if so
equipped, dump the grey and black water
holding tanks at an appropriate facility or
according to local public codes.
SANITIZING THE PLUMBING SYSTEM
Potable water systems require periodic
maintenance to deliver a consistent flow of
fresh water. For your personal safety, the
plumbing system should be sanitized when
your RV is new, at the beginning and end of
