Installation • Centrifugal Pump Suction Connection
When Flooded Suction Exits
• Suction piping that is undersized will create excess
friction losses that may cause cavitation and a
reduction in pump performance.
• Excess fittings and bends in suction line results in
trapped air, reduced performance, and high friction
losses which may cause cavitation.
• If check valve is required for back flow prevention,
locate on the discharge side of pump.
Not Recommended
See Pages 10 and 11 for
Swimming Pool Installation requirements.
Inverted Eccentric Reducer
may result in air pocket.
Check Valve
in suction pipe
not needed.
Concentric Reducer may
cause air pockets.
Valve in upward
position may trap
air.
Do not leave
valve partially
closed.
Unsupported
pipe causes
excessive stress
on pump and fittings.
Elbow immediately in front
of pump intake not recommended.
