WATER CONNECTIONS
IMPORTANT: The pump must not be connected to the power supply until the
hose/pipe installation is completed.
If any part of the system is to be connected to the mains water supply, do ensure
that you comply with your local water authority regulations.
Because of the variety of possible installations, no plumbing accessories are supplied
as standard with your pump, (except for the Handy Pump 2, which is provided
with a 4 metre inlet hose complete with a foot valve and filter). However,
accessories designed specifically for this range of pumps are available from your
CLARKE dealer and are listed on page 30.
The pump must always be installed and operated in a horizontal position i.e. with
the outlet port facing vertically upwards. The fixing holes in the base should be
used as necessary to secure the pump firmly in its operating position. (Not
applicable to the Handy Pump 2, which is portable). Also, ensure that there is
adequate air circulation around the motor.
Avoid situations where there is the risk of water coming into contact with the outside
of the pump. Neither the motor or the terminal box are designed to be waterproof.
These notes are for guidance on how to achieve a proper working system.
The schematic diagram opposite illustrates
a typical pipework installation.
The suction lift i.e. the vertical distance
between the water level and the pump
should not exceed the distance
specified for your pump. (See
Specifications, pages 9 to 11).
A foot valve and filter should be fitted
to the lower end of the suction hose,
as illustrated below, so as to help retain

water in the suction system and to prevent the possibility of large foreign bodies
entering the pump body.
A 1” BSP hose adapter will be required for connection to the inlet
port. This is available from your CLARKE dealer.
The performance of your pump will be effected by the diameter of the
inlet pipe - any restriction will greatly reduce the flow. We strongly
recommend that you use a diameter pipe which is as large as practicable,
with a suitable reducer for connection to the 1” BSP inlet adapter.
NOTE: The Handy Pump 2 is provided with a 4 metre inlet hose
complete with a foot valve and filter .
The delivery hose should be attached to the outlet adapter which is supplied.
IMPORTANT: In the case of the CBM250SS model, the hose MUST rise vertically
for 70cm before elbows are connected.
A gate valve may be installed in-line on the delivery side of the pump which can be set
as required to regulate the flow of water. DO NOT place any such restriction on
