The water purification system is located in the utility compartment in most models.
Other locations may include the kitchen, bath or hutch cabinet. If the water supply
has not been used for some time, allow the water to flow for several minutes to
flush the system. When not in use, the water filter cartridge should be stored out of
freezing temperatures. RV antifreeze will damage the water filter cartridge.
The water purification system manufacturer has supplied a plastic bypass hose
with fittings on either end that is designed to replace the water filter cartridge when
the motor home is being winterized. This plastic bypass hose is re-usable, store it
when it is not in use.
Each new RV is winterized with RV antifreeze before it leaves Jayco, Inc. To
use the water purification system the clear plastic bypass hose must be
removed and the water filter cartridge installed.
Replacing the water filter cartridge
Replace the water filter cartridge 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 manufacturer’s owners manual and the label on the water filter
cartridge.

To drain the fresh water holding tank and supply lines:
1. Open all faucets, including the outside shower faucet.
2. Open the “fresh tank drain” valve.
All permanent fresh water tanks can be drained by one of
two types of drain valves. A white plastic drain is
attached to the exterior wall (open valve to drain) or a
valve located inside the motor home adjacent to the water
tank (this knob turns 45° to open or close).
3. Open the “low point drains” by turning, then pulling the
handles up.
As their name indicates, they will be at the lowest point of
water lines. A label is 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 motor home.
Once the label is found on the exterior sidewall, go inside
the motor home to find the corresponding location of the
drains.
4. Turn ON the water pump and allow it to run as needed.
5. Operate the toilet flush lever until water stops flowing.
6. Relieve the water pressure using the P&T valve BEFORE removing the water
heater drain plug.
7. Otherwise, if there is any water pressure present the water will spray out of
the opening when the drain plug is removed.
