Dave Throup from the Environment Agency said there are reports of around 15 to 20 houses that were flooded in Kempsey despite having a flood defence scheme there.
Dave Throup said it appears one of the pumps failed to work during the point of the heaviest rainfall.
The pumps are designed to pump water away from the village that has been affected by flooding in the past.
He added that the pumps are now working as they help residents deal with the flooding.
People who were flooded when a new Environment Agency pump failed in the floods were told today they may get a new early warning system.
Residents in Kempsey will today find out why their brand new water pump failed during December's floods in a drop in session.
