SERVICES      WATER SYSTEM

          Water system - Introduction

          All Swift Group motorhome water systems
          have been designed around a pump fitted
          within the motorhome. This pump draws water
          from an under floor or internal water tank,
          to provide water pressure within the water
          system, whenever it is switched on and water
          is available.

          The schematic below shows the basic
          configuration of the water system:

          When power is supplied to the pump, it will       1. T hrough blue water pipes routed directly to
          draw water from the water tank, and pump             the cold connection of each tap.

          heater.                                           2. To the water heater.

          The pump is fitted with its own pressure          Water from the pump enters the bottom of the
          switch, and the pump will continue to pump        water heater. Once the water fills the water

          of the pump reaches a pre-set level. For this     water heater via a connection at the top of that
          pressure to be achieved, the taps must be         water heater. This water, which is still under

                                                            each tap via the red pipes.
          When the taps are opened, water will leave
          the tap via the spout, and the pressure in the    To winterise the system please see

          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.

          Close to the pump, the water under pressure
          is split into two paths:
