Water Filter Care and Maintenance
This article provides basic care and maintenance recommendations for water filters. Your coach may be equipped with a
fresh water filtration system. This system uses extruded carbon filter cartridges to remove sediment and certain impurities
from the incoming water supply. The filter assembly is located in the basement water compartment. Select coach models
may also have additional filters installed for drinking water.

When To Replace Your Filters
Most water filter manufacturers recommend that you
replace your water filters every six months. These
guidelines are based more on average household size
and average consumption rates rather than your specific
coach. The frequency of filter changes depends upon
your water usage and the quality of water you are using.
As you travel and hook up to different water sources
some may contain more sediment, metals, sulfur and
other impurities which affect the filter life, the taste and
smell of your water. Other factors are how often it is used
and stored and how long water is able to sit in the holding
tank and become warm and stagnate.
Change the filter at least every six months and at any time
you notice decreased water flow or notice unpleasant
taste, odor, or algae after flushing and sanitizing the water
system. Water filters and fresh water system maintenance
are the customer’s responsibility in order to ensure safe
potable water.
Flow-Pur Whole House Water Filters
This article provides basic instructions for replacing a Flow-Pur Whole House Water Filter. Replacement filter cartridges are
available through the Newmar parts department. For parts inquiries, refer to the NewPar (formerly ComNet) parts catalog or
contact the parts department at 1-800-731-8300 (option #1).
CAUTION
!
When replacing the filter, make sure the rubber
O-Ring seal is properly positioned in its groove in
the cartridge housing. An improperly positioned or
missing seal will cause leakage around the perimeter
of the filter housing.
1. To replace the filter cartridge, turn off
the water supply to the coach at the
city water connection, or turn off the
water pump if using potable water.
2. Drain the water pressure off the
system by opening a faucet or low
point drain, and press the red button
on top of the filter housing.
3. Unscrew the filter canister by
rotating to loosen and remove it (the
top housing has male right hand
threads, and the canister portion has
female threads).
4. Insert the new filter cartridge, positioning it so the
opening in the bottom of the filter is placed on the
molded ring at the bottom of the canister.
Do not allow water to freeze in the water filter
canister. Freezing will crack and permanently damage
the filter housing and associated plumbing. Always
remove the filter cartridge prior to winterization.
IMPORTANT
!
5. Reattach the canister to the filter housing by rotating
the canister until it tight. Do not over tighten the
canister when attaching it back to the housing.
Exterior Shower Overview
An exterior shower located in the water compartment on the driver side may be an optional feature on your coach and can
be used to rinse off sand or grass, muddy shoes, or bathe a pet outside of the coach. The exterior shower may also be used
to wash your hands or rinse off the sewer hose after dumping the waste water tanks.
