Thank you for your question, TomFaucet! I apologize for the inconvenience with this installation. We recommend using plumbers tape where this assembly screws onto the tailpiece as instructions suggest on page 5, step C of the Maintenance and Installation manual below for a model that also uses this assembly. We advise putting the thread seat tape on clockwise and no more then three time around. If you need further assistance, please feel free to contact us directly.
Best regards, Edward
