Hi, I wonder if I can take water from a faucet and sink that isnt kosher for Pesach and cםok it in my kosher for pesach kettle or does that make the kettle returning un kosher for pesach?

ב"ה Shalom The water which comes from your faucet has no Chametz in it . Even if the sink was not yet made kosher for Pessach ,it has no effect on the water itself. Therefore, your kettle is fine for Pessach. Happy and kosher Pessach
