Question:
Is everyone mechuyov to kasher their kitchen counters for pesach or is it enough just to cover them? Do you also have to kasher the sinks if you put in a sink insert?
Answer:
This is the minhag, to kasher the counter tops and sinks, even though they will be covered anyway. Besides there are times when the water seeps through. It is true it is extra work, but Hashem will pay us back for all the hard work we do for His mitzvos.
Have a good Yom Tov
