2022 Interstate 24X
Water Pump and Strainer
The water pump is controlled by the switch under
the galley roof locker� Once the switch is turned on,
the pump will run until the water pressure reaches
approximately 50 psi� At this point, an internal pressure
switch will shut it off� When a faucet is opened, the
water pressure will drop and the pump will start to run
again�
As a general rule, the water pump should be turned off
while using a city water hookup; however, the water
pressure at some campgrounds may be low� The water
pump can be turned on to assist the city water hookup
pressure� Be sure there is some water in the fresh
water tank� The pump will only use the water that is
needed out of the tank to bring the pressure up to the
usual standard of 50 psi�
The water pump and strainer are located below the
refrigerator, accessed by removing the vent� The
strainer should be visually checked for accumulation of
sand or debris that could affect water flow.
To clean the strainer screen: with the clear plastic at
the top, press on the sides of the strainer releasing
the tabs holding the clear plastic top in place, hold the
sides in, and pull straight up on the clear plastic top to
remove the screen assembly� Rinse all debris from the
screen� Replace the screen assembly by aligning the
screen in the seating groves and pressing gently down
until the tabs catch and hold the clear plastic top in
place�
The inlet and outlet hoses and the strainer assembly
are held in place by self-sealing, blue, quick-connect
fittings. To disconnect a hose or the strainer, grasp
the blue tab on the female fitting by the grooved finger
edges and pull straight out on the tab� This will release
the male fitting connected to the hoses and strainer.
Be sure that both the female and male fitting on the
disconnect are free of all debris and are not damaged
before replacing� Check the pump system for leaks any
time the disconnect fittings on the hoses and/or strainer
are removed�
CAUTION
Failure to check the quick disconnect fitting for
water leaks when reinstalling inlet and outlet
hoses or the water pump strainer may cause the
pump system to leak, causing damage to personal
property.
Sanitizing
Potable water systems require periodic maintenance
to deliver a consistent flow of fresh water. Depending
on use and the environment the system is subject to,
sanitizing is recommended prior to storing and before
using the water system after a period of storage�
Systems with new components, or ones that have been
subjected to contamination should also be disinfected
as follows:
1� Use one of the following methods to determine the
amount of common household bleach needed to
sanitize the tank�
a� Multiply “gallons of tank capacity” by 0�13;
the result is the ounces of bleach needed to
sanitize the tank�
b� Multiply “Liters of tank capacity” by 1�0; the
result is the milliliters of bleach needed to
sanitize the tank�
2� Mix the proper amount of bleach into a container of
water�
3� Pour the correct amount of solution (water/bleach)
into the Fresh Water tank and fill with potable
water�
4� Open all faucets (hot and cold) allowing the water
to run until the distinct odor of chlorine is detected�
5� The standard solution must have 4 hours of contact
time to disinfect completely� Doubling the solution
concentration will allow for contact time of one (1)
hour�
6� When the contact time is completed, drain the tank�
Refill with potable water and flush the plumbing of
all sanitizing solution�
NOTE
The sanitizing procedure outlined above is in
conformance with the approved procedures of
RVIA ANSI A 119.2 and the U.S. Public Health
Service.
