I'm looking for a qualified tradesperson to replace my kitchen faucet. The current faucet leaks occasionally and the handle feels loose. I'd like a straightforward swap to a standard single-handle mixer faucet. Please include any parts or tools you bring and confirm compatibility with a standard 15mm supply line. I prefer a tidy install with minimal disruption, and I'll provide the new faucet if you want to use it. Availability in the next week or two would be great, and I can accommodate mornings or early afternoons. Thanks!
