•Use pipe, tubing, or reinforced hose to make suction connection. Hose must have sufficient strength to resist collapse under the atmospheric pressure differential that may occur while pump is running.
•It is important, even with a flooded suction condition, that proper pipe fittings are used so water is delivered to impeller eye with a smooth flow and consistent velocity.
•Suction pipe size should be at least one commercial pipe size larger than opening of pipe inlet. Flow velocity should not exceed 8 ft./sec.
•An isolation valve is used in a pressurized suction pipe to permit servicing pump.
•Piping run and connection fittings should be properly aligned and independently supported to reduce strain on pump case.
•If solids are present, a strainer should be used to protect the pump.
