Here you go :slight_smile:

This stops all types of liquid from flowing

    @Listener
    public void stopLiquidFlow(ChangeBlockEvent.Place event, @Root BlockSnapshot snapshot) {
        Optional<MatterProperty> matter = snapshot.getState().getProperty(MatterProperty.class);
        if (matter.isPresent() && matter.get().getValue() == Matter.LIQUID) {
            event.setCancelled(true);
        }
    }
