Question:
We were leaving our sink for 24 hours to kasher for pesach but then someone used the sink to wash out a bowl with cereal in it with warm/hot water. Do we need to restart the 24 hours?
Answer:
If the water theat got chometzdik was in the boel and then the water went into the sink it is not worse than a kli sheini, and you wouldn’t have to wait any longer.
Chag kasher v’samech
