Which is better to use under the lip edge of a pop up drain pipe on the inside of the porcelain bowl?

Best Answer

You want to use plumbers putty for a drain pipe like that. If you put silicone between those two parts, especially if these are new and pristine clean, you would likely never get it back out without a huge amount of work. And in trying to remove it you would risk major damage to the porcelain sink bowl.
