Two things.
A valve is not operating correctly (opening/closing) or one or more seals were damaged in the incident.

Either way, it needs to be taken apart and just replace the seals and valves and check if any of the pistons

have cracked.

How old is the unit (pump) and when was the last time you had anything like this work done?
