backwashed

Reversed the current

Backwashed describes something that has been affected by backwash—water or liquid pushed backward.

A backwashed pool has had its filter cleaned by reversing water flow.

In surfing or boating, backwashed waves have rebounded off a shore or seawall.

Figuratively, something backwashed has been tainted by contact with someone's mouth: I'm not drinking that—it's backwashed.
