WATER SYSTEMS
Troubleshooting
If the water pump cycles after closing the
faucets, drain valves and inlet valves, a leak may
be present. At this time check for leaks around
ttings, valves, lters and connections of the hot
and cold water system. If problems continue,
take the motorhome to an authorized dealer for
repair.

Disinfecting Fresh Water
Disinfecting the water system with household
bleach (superchlorination) protects against
bacteriological or viral contamination from
common water sources.
Disinfect the fresh water system:
If the motorhome is new.
If the motorhome has been in storage.
Every three months during use.
NOTE
Use the gravity fill to perform this task.
Remove cap from the gravity fill. Add
the solution. When finished, secure the
gravity fill cap.
To Disinfect the Water System:
Remove the water line connections and
connect the bypass hose to the water
lines (see “Water Filter).
Prepare a household chlorine bleach
solution of 1 gallon water and ¼ cup of
chlorine bleach. Use 1 gallon of solution
for every 15 gallons of tank capacity.
E.g.: Add 2-2/3 gallons solution to a 40
gallon tank. This mixture puts a 50 ppm
(parts per million) residual in the water
system, and acts as a quick-kill dosage
for harmful bacteria, viruses and slime-
forming organisms. Concentrations
higher than 50 ppm may damage the
water lines and/or tanks.
Turn the water pump OFF.
Drain the fresh water tank. Close the
drain and pour the solution into the fresh
water tank using the gravity ll and a
funnel.


Turn the water pump ON. Open each
faucet, in turn, and run the water until
you smell a distinct chlorine bleach odor.
Do not forget the hot water, tub and
shower faucets.
Allow the system to stand for 4 hours.
Drain the system and ush with fresh
water. The water tank and low point
drains are located in the roadside water
service center. Flush with fresh water
repeatedly until the water system no
longer smells or tastes like chlorine
bleach.
Install new water lter. Remove bypass
hose and store. Reconnect water lines to
water lter.
TIP
Use the same hose labeled for potable
water to introduce the chlorine solution
into the system. This will disinfect
the potable water hose at the same
time. Several flushes will be required
to remove chlorine residue from the
potable hose.
INFORMATION
Household bleach is 5.25% Sodium
Hypochlorite. Higher concentration will
increase PPM ratio.
