I'm installing a Push Button (not pop-up) drain in my pedestal sink. A rubber washer goes between the metal drain and the sink (another rubber washer goes under the sink). Is it still appropriate to use plumbers putty in this situation?

Increasingly, I'm finding that plumber's putty is not recommended for sink drains, especially if it has its own rubber gasket. In places where the manufacturer does not supply a gasket (and the flange is not metal) they suggest silicone caulk.
Be sure to read the directions for your drain assembly!

I would not use putty. Be sure the bottom of the sink is clean and smooth.The rubber gasket should be sufficient to seal without putty.

Get answers to practical, detailed questions
Focus on questions about an actual problem you have faced. Include details about what you have tried and exactly what you are trying to do.
Ask about...
- Questions you would typically ask a home contractor.
- Which tools, materials, and best practices for home improvement task.
- Identifying the source or cause of a problem within your home.
- National building codes (of any country).
- Installation, maintenance, and repair of major appliances.
- Carpentry and woodworking.
Not all questions work well in our format. Avoid questions that are primarily opinion-based, or that are likely to generate discussion rather than answers.
Questions that need improvement may be closed until someone fixes them.
Don't ask about...
- Anything not directly related to home improvement
- Hobby projects, decorating advice or landscaping.
- The cost of a job or the price of tools as these will vary between locations and over time.
- Questions that are primarily opinion-based
- Questions with too many possible answers or that would require an extremely long answer

All questions are tagged with their subject areas. Each can have up to 5 tags, since a question might be related to several subjects.

When I last installed a sink in my home, I used plumber's putty per manufacturer's instructions. The drain leaked. I redid the whole thing with more putty. The drain leaked. I redid it again with silicone and it's been dry ever since. - Matthew Leingang Aug 1 '17 at 17:37
