Customer stated that the kitchen sink is leaking again. Found right side basket strainer leaking out of the seal. The basket strainer does not have any of the gaskets on the bottom side and is using rubber seal instead of putty. Checked the left side basket strainer and it is in the same condition. Replaced both basket strainers so there is no more leak. Left side of sink has no ptrap. Installed ptrap and tested. Job is completed.
