PRESSURISED WATER SYSTEM
PRESSURISED WATER SYSTEM
Pump
Fresh water is supplied to the caravan from an
external water container by the Carver Crystal
Filter System, which consists of a socket
located near the battery box, on the offside of
your caravan and a separate plug-in pump
assembly. The socket is protected by a hinged
lid which should be kept shut when the pump
is not connected. The lid is easily opened by
gripping the lower edge and pulling outwards.
The separate plug-in pump assembly consists
of a submersible pump, hose and plug. The
plug provides connection to both water supply
to the caravan and 12 volt DC electric power
to the pump. A dust cover is fitted to the
connecting dual hose to prevent contaminants
falling into the water container.
Pressure Switch
In most modern caravans the water system is
pressurised. When a tap is closed pressure of
water builds up in the system. At a
predetermined level, the pressure will operate
a “pressure switch” which, in turn, will stop the
pump running. Opening a tap will reduce the
pressure and the pump will start running. At
normal flow rates the submersible pump
should operate continuously - but at low rates
the pressure switch will cycle on and off to
maintain back pressure in the system, an
adjustment to the switch’s diaphragm
sensitivity is required. This also may be
required, usually because the power supply
voltage has varied by more than ± 0.5 volts.
The possible causes are:
1. Battery drainage through normal use.
2. Setting the switch when on mains electric
supply (typically 230 volts) then using a 12
volt battery.
3. Setting the switch when on 12 volt battery
then using mains electric supply (230
volts).
To adjust the pressure switch:
1. With the system properly primed, close all
taps and showers.
2. Leave the pump run switch (located on the
12 volt distribution panel) turned on.
3. Tighten the adjusting screw clockwise. The
pump should now be running.
4. Partly open one cold tap to allow water to
flow at about 1 pint in 15 seconds.
5. Slowly loosen the adjusting screw, by
turning anti-clockwise, until you can hear
the micro-switch start to click. The
diaphragm will then be properly adjusted.
