PUMP LOCATION: The pump should be installed in a clean, dry
and ventilated location which provides adequate drainage and
room for servicing and protection from freezing temperatures. It
should be bolted down evenly on a good foundation, preferably
concrete, to prevent the development of unnecessary stress.
Locating the pump as close as possible to the source of water
supply reduces the friction losses in the suction pipe and provides
for maximum capacities.
SUCTION PIPE: It is recommended that only new clean pipe
or hose be used and the size be the same as that of the pump
suction tapping. If the pump is installed any appreciable distance
away from the source of water supply, the suction pipe should

be increased by one size. The suction pipe must always slope
upwards from the water source to the pump to avoid air pockets in
the line. In cases where the pump has to be reprimed often and it
is not necessary that a lot of water be delivered, it is advisable to
use a 90° or 45° elbow on the suction line. This enables the pump
to prime sooner and also prevents kinking of the hose. In cases
where a maximum volume of water is required over a prolonged
period of time, the suction line should be led almost horizontally
to the pump. Non-toxic thread compound should be used on all
pipe joints and connections should be thoroughly tightened. A
strainer should be connected to the bottom end of the suction
pipe and it should be well submerged at all times.
