Plumbing – Should I use plumbers putty to install a sink drain

drainplumbing

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!
