As close as possible
•Use pipe, tubing, or reinforced hose to make suction connection. Hose must have sufficient strength to resist collapse under the pressure differential that occurs while pump is running.
•Suction pipe size should be at least one commercial pipe size larger than opening of pump inlet. Flow velocity should not exceed 8 ft./sec.
•Suction screen must screen out solids that could clog pump impeller.
•Suction screen area must be at least four times suction pipe area.
•Net Positive Suction Head Available (NPSHA) must exceed Net Positive Suction Head Required (NPSHR) by the pump or reduced performance and severe pump damage may result.
•All suction piping must have continuous rise to the pump suction inlet. A 1/4 inch per foot minimum slope is recommended.
