If the MSO sprayer sits for a period of time unused, it is possible that the intake valve may stick to the body of the valve, preventing it from priming.

If this occurs, remove the suction line from the pump, insert a screwdriver or similarly sized object and push gently to free the valve.

Pouring some water into the valve may also help further.
