Since there is a lot of activity in my kitchen throughout the year and the faucets are saturated with quite a bit of chametz, for my own peace of mind, instead of kashering the faucets, I simply replace them for Pesach, and after Pesach I switch them back. It’s certainly a stringency, but for me, it brings peace of mind for the holiday.
This year, I shut off the main water valve of the apartment and began dismantling the kitchen faucets. Suddenly, I saw my little child walk into the kitchen holding a dismantled faucet head. I looked and realized it looked remarkably similar to the faucet near the living room. I went to check and indeed, I was not mistaken. It turned out he had been playing with the faucet, and since it was already old and decayed, it came off in his hand. The incredible hashgacha was that he happened to play with the faucet exactly during the few minutes when I had turned off the main water flow to the house—because had it happened a minute earlier or later, we would have had a flood of water pouring into the living room and surrounding areas, right after everything had been cleaned and prepared for the holiday of Pesach!!!
