How to Pick a Bathroom Sink Drain – Pop Up Drain

When picking a bathroom sink drain pipe check the size of your opening in the bottom of the sink. If it is around 1 5/8 inch you would use a standard 1 1/4 drain pipe. Check for an overflow hole in the sink. If you have one get a drain pipe with a hole, if no overflow get a drain pipe without a hole. Most will need plumbers putty to seal the top flange. Use stain free putty.
