Arrived on site client stated they would like for us to install their new kitchen faucet. Upon inspection underneath the sink I found that the shutoff do turn but advised customer that since they are old it’s best to replace them to prevent any issues when turning the water back on. Client would like to replace all valves under sink and have the faucet they supplied installed today. After removing the old valves and installing the ones I tested for leaks. There are no leaks at this time. Installed customer supplied faucet and tested for leaks again. There are no leaks.
