4.3. Valves and Fittings
1). Do not install 90° elbows directly into pump inlet. Elbows should be no closer than 250mm
to the inlet. Joints must be tight. Suction line diameter must equal or be larger than the
discharge line diameter.
2). Flooded suction systems should have gate valves installed on suction and discharge pipes
for maintenance, however, the suction gate valve should be no closer than five times the
suction pipe diameter as described in this section.
3). Use a check valve in the discharge line when using this pump for any application where
there is significant height to the plumbing after the pump.
4). Be sure to install check valves when plumbing in parallel with another pump. This helps
prevent reverse rotation of the impeller and motor.
