Why is my ITT Water Pump not delivering liquid?

If your ITT Water Pump isn't delivering liquid, several factors could be at play. First, the pump may not be primed; re-prime it, ensuring both the pump and suction line are full of liquid. A clogged suction line could also be the culprit; remove any obstructions. Similarly, a clogged impeller can prevent liquid delivery, so back-flush the pump to clean it. Ensure the shaft rotates in the correct direction, matching the arrow on the bearing housing or pump casing. Insufficient submersion of the foot valve or suction pipe opening can cause issues; consult an ITT representative for the proper submersion depth and use a baffle to eliminate vortices. Finally, a suction lift that's too high can hinder liquid delivery; shorten the suction pipe.
