Fixing Kitchen Sink Supply Line Leaks: Mineral Buildup and Gasket Issues

Fixing a Leak at Kitchen Sink Supply Line: FAQ

Customer: I encountered a leak at the connection point of the supply line to my kitchen sink faucet. After an unsuccessful attempt to tighten it, I turned off the water and disconnected it. I noticed mineral buildup on the gasket. Is it possible to clean this and reconnect it? If yes, what should be used to remove the mineral buildup?

It's advisable to replace the supply line since its gasket has become deformed and may not seal properly.

Can you assist in identifying the replacement line required for purchase?

Plumber: Rick

Could you show me the shutoff valve under the sink? Please ensure the view isn't too close, so I can see the surrounding area as well.
