: I have installed American Standard bathroom faucets. There was a vaseline type substance in the connectors for the hot and cold water lines. I wiped out as much as I could, but now that the faucets are up and working, there is a horrible taste and smell in the water. Any advice?
The substance is most likely plumbers grease. Some manufacturers will ship new plumbing parts like this. The smell and foul taste should dissipate rather quickly, if it doesn't, you need a professional to check the system, the problem may not be with the newly installed faucet.
Let the faucet run H & C for a few minutes.
Good Luck. e-plumber
