Suction Connection
Suction Lift
Do not use
Concentric
Reducer.
No support or 
uneven mounting 
not recommended. 
Excess use of pipe fittings means potential air leaks.
Elbow immediately in front of pump intake not recommended.
Concentric Reducer causes high spots
along the suction line resulting in air pockets.
Do not install valves in suction line.
Unsupported pipe causes excessive stress
on pump and fittings.
Long run
not recommended
Pipe diameter
("D") undersized
reduces performance
High suction lift should be avoided.
Vortex caused by insufficient submergence may cause pump to lose prime.
•Suction pipe sloping downward to pump inlet will trap air which will reduce performance and may cause pump to lose prime.
•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.
