8.6.5 Plumbing Design
CAUTION – New pumps are covered
with foam plugs to prevent contamina-
tion. Remove the foam plugs before
connecting pipes.
CAUTION – Handle the pump with
caution, never use force on it.
Minimize suction lift – to max. 3 m total pressure loss
(2 m for pumps with flow rate greater than 400 l/h (105 US
Gal)). The less suction lift, the more reliable and quiet the
pump will be. The motor may not be submerged, this will
damage the pump.
Intake pipe – The intake pipe may run any reasona-
ble horizontal distance, although it is best to keep it short.
Use large pipe for the intake (1 to 1 ½” for larger booster
pumps). Slope the intake line from the water source up to-
wards the pump. Avoid humps in the intake line that cause
air pockets which can block the flow.
CAUTIONAvoid leaks in the suction
line. The pump will prime insufficiently or
not at all.
The intake pipe must be sized generously to avoid high
pressure drop at peak flow rate, or the pump will be noisy
and will wear rapidly.
Use pipe reducer fittings to adapt the pumps’ inlet or outlet
to larger pipe size where necessary. Larger pipe sizing does
not have a negative effect.
CAUTIONThe intake must not be
restricted by undersized pipe, excessive
suction lift, or a clogged filter.
CAUTION – Excessive suction at the
pump intake causes cavitation, resulting
in noise and rapid pump wear.
CAUTION – Do not use thin wall hose or
soft tubing on the pumps’ intake. It may
collapse under suction and restrict the
flow.
CAUTION – Do not use polyethylene
pipe for the suction side. It is prone to
leakage at the fitting.
Inline filter – Inline filters should be mounted horizontal-
ly and as low as possible. This prevents any air trapped from
blocking the water flow.
Foot valve – The foot valve is a check valve installed at the
water intake. It is required in any situation where the pump
is located higher than the lowest water level of the wa-
ter source. A high quality spring loaded type is recommend-
ed to avoid loss of prime. A check valve allows water to flow
one way only.
