Arrived on site client stated that he had a leak under the kitchen sink. Upon inepction I noticed a little bit of moisture underneath the basket strainer. Client stated he thinks thier maybe another leak on the nut for the trap arm but during testing I did not see any others other than the basket strainer at this time. I also noticed the valves were corroded but client wanted to just replace the basket strainer at this time. When done I tested with hot water and filled the sink up. There are no leaks at this time.
