Narrative:

Approximately 15 mi out from las, base to final at 8000', dispatch called and spoke with first officer. They said to seal off both lavs because the lav water was mixed with gasoline. They told us to completely flush out the lavs twice and then refill. If everything looked ok, we were told to continue on. Before lav service was started, I checked both lavs by flushing them and noticed nothing out of the ordinary. They were both flushed out twice and we continued on. Before leaving san, I used the front lav myself and noticed nothing out of the ordinary.
