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:
NOTE:
The sanitizing procedure is in conformance with the approved
procedures of RVIA ANSI A119.2 and the U.S. Public Health Service.
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 into solution the proper amount of bleach within a container of water.
3.
Pour the solution
(water/bleach)
into the tank and fill the tank with potable water.
4.
Open
all
faucets
(Hot&Cold)
allowing the water to run until the distinct
odor of chlorine is detected.
5.
The standard solution must have four (4) hours of contact time to
disinfect completely. Doubling the solution concentration allows for
contact time of one
(1)
hour.
6.
When the contact time is completed, drain the tank. Refill with potable
water and purge the plumbing of all sanitizing solution.
WINTERIZING
If water is allowed to freeze in the system, serious damage to the plumbing
and the pump may occur. Failures of this type will void the warranty. The
best guarantee against damage is to completely drain the water system.
NOTE:
When used per the manufacturers recommendations
non-toxic
antifreeze for potable water
is safe for use with SHURflo pumps.
Refer to the coach manufacturer and other equipment
manufactures for their specific winterizing & drainage instructions.
CAUTION
:
Do not
use Automotive Antifreeze
to winterize potable water
systems. Such solutions are highly toxic. Ingestion may cause
serious injury or death.
To properly drain the system perform the following:
1.
Drain the water tank. If the tank doesn't have a drain valve, open all
faucets allowing the pump to operate
(15 min. ON / 15 min. OFF)
until the
tank is empty.
2.
Open all the faucets
(including the lowest valve or drain in the plumbing)
and allow the pump to purge the water from the plumbing, then turn the
pump OFF.
3.
Using a pan to catch the remaining water, remove the plumbing at the
pump's inlet/outlet ports. Turn the pump ON, allowing it to operate until the
water is expelled. Turn OFF power to the pump once the plumbing is
emptied. Do not reconnect pump plumbing. Make a note at tank filler as a
reminder: "Plumbing is Disconnected".
4.
All faucets must be left open to guard against any damage.
TROUBLESHOOTING
Vibration induced by road condition can cause plumbing or pump hardware to loosen. Check for system components that are loose. Many symptoms can
be resolved by simply tightening the hardware. Check the following items along with other particulars of your system.
PUMP WILL NOT START/ BLOWS CIRCUIT:
!
Electrical connections, fuse or breaker, main switch, and ground connection.
!
Is the motor hot? Thermal breaker may have triggered; it will reset when cool.
!
Is voltage present at the switch? Bypass the pressure switch. Does the
pump operate?
!
Charging System for correct voltage
(±10%)
and good ground.
!
For an open or grounded circuit, or motor; or improperly sized wire.
!
For seized or locked diaphragm assembly
(water frozen?)
.
WILL NOT PRIME/SPUTTERS:
(No discharge/Motor runs)
!
Is the strainer clogged with debris?
!
Is there water in the tank, or has air collected in the hot water heater?
!
Is the inlet tubing/plumbing sucking in air at plumbing connections
(vacuum leak)
?
!
Is inlet/outlet plumbing severely restricted or kinked?
!
Proper voltage with the pump operating
(±10%)
.
!"
For debris in pump inlet/outlet valves or swollen/dry valves.
!"
Pump housing for cracks or loose drive assembly screws.
SERVICE KITS
To insure the correct service kit, order by the complete model number,
date of manufacture and other name plate data. Part kits come with
complete repair instructions. Pump illustrations may not be representative
of all SHURflo potable water pump models and are only for depiction of the
various parts kit assemblies.

Switch / Check valve and Upper Housing Kit
(Replaces all previous switch designs)
2
Valve plate assembly
3
Diaphragm / Drive assembly
4
Motor
5
Complete Pump Head assembly (includes parts
#
1, 2, 3)
(Replaces all previous switch designs)
PUMP WILL NOT SHUT-OFF / RUNS WHEN FAUCET IS CLOSED:
!
!!
!
Output side
(pressure)
plumbing for leaks, and inspect for leaky valves or toilet.
!
!!
!
For air trapped in outlet side
(water heater)
or pump head.
!
!!
!
For correct voltage to pump
(±10%)
.
!
!!
!
For loose drive assembly or pump head screws.
!
!!
!
Are the valves or internal check valve held open by debris or is rubber swollen?
!
!!
!
Pressure switch operation/adjustment, refer to shut-off adjustment for switch.
NOISY OR ROUGH OPERATION:
!
For plumbing which may have vibrated loose.
!
Is the pump plumbed with rigid pipe causing noise to transmit?
!
Does the mounting surface multiply noise
(flexible)
?
!
For mounting feet that are loose or are compressed too tight.
!
For loose pump head to motor screws.
(3 long screws)
!"
The motor with pump head removed. Is noise from motor or pump head?
RAPID CYCLING:
!
For restrictive plumbing, flow restrictors in faucets/shower heads.
!
Water filter/purifier should be on separate feed line.
!
Pressure switch shut-off adjustment.
LEAKS FROM PUMP HEAD OR SWITCH:
!
For loose screws at switch or pump head.
!
Switch diaphragm ruptured or pinched.
!"
For punctured diaphragm if water is present in the drive assembly.
