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/splutters:
(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 the 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.
Pump will not shut-off/runs when tap
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
incorrect, 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:
• Pressure switch shut-off adjustment.
• Water filter/purifier should be on separate
feed line.
• For restrictive plumbing, flow restrictors in
taps/shower heads.
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.
SERVICE KITS
To ensure the correct service kit, order by the
complete model number, date of manufacture
and name plate data. Parts kits come with
complete repair instructions.
1. 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 (replaces
all previous switch designs).
least 13mm (½') ID. for main lines.
Restrictive fittings and connections
(elbows, ‘T’s’, feeder lines to taps, etc.)
SWITCH SHUT-off
Restrictions in a plumbing system may cause
the pump to rapid cycle (ON/OFF within 2
seconds) during low flow demands. Cycling
should be minimized to prevent pulsating
flow, and to achieve maximum pump life.
To determine if adjustment is necessary, turn
tap on to lower than average flow of water.
The pump should cycle, but its ‘OFF time’
must be 2 seconds or longer. If the cycling is
correct, leave well enough alone. If the pump
is cycling rapidly increase the setting by turning
the screw clockwise (1½, turn maximum)
until the pump operates for 1 second with at
least 2 seconds ‘OFF time’. If cycling cannot
be minimized consider removing plumbing
restrictions or install an accumulator.
SAnITIZInG
Fresh water systems require periodic
maintenance to deliver a consistent flow
of fresh water. Depending on the 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:
Use the following method to determine the
amount of common household bleach needed
to sanitize the tank.
1. Multiply ‘litres of tank capacity’ by 1; the
result is the millilitres 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 fresh water.
4. Open all taps (HOT & COLD) allowing the
water to run until the distinct odour of
chlorine is detected.
5. The standard solution must have four
hours of contact time to disinfect
completely. Doubling the solution
concentration allows for contact time of
one hour.
6. When the contact time is completed, drain
the tank. Refill with fresh water and purge
the plumbing of all sanitizing solution.
noTE: The sanitizing procedure outlined
above is in conformance with the
approved procedures of RVIA AnSI A119.2
and the USA Public Health Service. It may
not be permitted or recommended in
certain countries.
WInTERISInG
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.
However, non-toxic antifreeze for fresh water,
if available at local caravan centres, may be
used.
CAUTIon: Do not use Automotive
Antifreeze to winterize drinking 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 taps allowing
the pump to operate (15 min. ON, 15 min.
OFF) until the tank is empty.
2. Open all the taps (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 taps must be left open to guard against
any damage.
