A homeowner reported low water pressure in the kitchen faucet. After inspecting the plumbing, I found mineral buildup in the aerator and corrosion in the supply lines. I replaced the old copper supply lines with new flexible braided stainless steel hoses and cleaned the faucet aerator. After reassembling, I tested the system and restored full water pressure. I also checked for leaks under the sink and inspected the shut-off valves to ensure they were functioning properly. The homeowner was advised to monitor water quality to avoid future buildup.
