Customer called regarding a leak under the kitchen sink. Upon arrival, I inspected the area and found the kitchen faucet was leaking from the supply line, which could not be repaired. I also observed that the emergency shut-off valves were old and deteriorating, posing a risk of failure and potential leaks. I provided an estimate to replace both the faucet and the shut-off valves, which was approved. I installed a new brushed nickel American Standard gooseneck kitchen faucet and two new 1/4-turn dual shut-off valves. All work has been completed and tested with no issues.
