. The Ultraflow Compact (right) inlet is used to
bypass the tank.
An external pump is supplied with the
caravan, this can be used with the left inlet
when the on-board pump is being used to
draw water from an external source.
The same external pump can be used with
the right inlet, this will transfer water from the
external source to the internal tank.
A red selector valve located close to the
pump is used to select the water supply from
the external source or the internal tank (see
valve positions).
Using the water tank
Bypassing the water tank
The inboard pump draws water from
whichever water source is in use. When
power is supplied to the pump, it will draw
water from a selected source and pump it to
the caravan taps, shower and water heater.
The pump is fitted with its own pressure
switch and the pump will continue to pump
water, until the pressure of water on the
output of the pump reaches a pre-set level.
For this pressure to be achieved, the taps
must be closed. When the taps are opened,
water will leave the tap via the spout and the
pressure in the pipes between the pump and
the taps will reduce. Because of this
reduction in pressure, the pressure switch on
the pump will switch back on and the pump
will again run to pump more water. The water
under pressure is split into two paths.
1. Through blue water pipes routed directly
to the cold connection of each tap.
2. To the water heater. Water from the
pump enters the bottom of the water
heater. Once the water fills the water
heater (typically 10 litres), water then
leaves the water heater via a connection
at the top of that water heater. This water,
which is still under pressure, then routes
to the hot connection of each tap via red
pipes.
On arrival at the campsite / priming the
system the caravan water system can be
used with or without the internal water tank.
