Customer stated: they had a leak under a sink. Tech notes: called out today to look at a leak under a sink. While on site I found there was a piece of tubular that had a crushed gasket on it. I removed a piece of tubular along with the red smashed gasket. Resolution: I replaced the red gasket with a blue tubular gasket. Once gasket was replaced I reinstalled the tubular and tested to find no further leaks or drips. Job status: complete. This estimate is to remove a piece of tubular and replace a tubular gasket and reinstall the existing tubular with new gasket under the kitchen sink.
