I recently refurbished a restaurant and had plumber put in new toilet. After toilet install, the men's room smells like sewage. Not the best smell for a restaurant. What can be done to correct this problem? plumber will not answer my calls.

Pull and reset the toilet using a new wax seal. Good luck, Tom
