Step #7: Remove Excess Plumber’s Putty from Sink

Remove any excess putty from the inside of the sink around the strainer opening. Attach the tailpiece to the sink drain, and test it for leaks.

Further Information


  1. I removed excess putty from the bottom of the sink opening and strainer. However as I tightened the locknut washer some putty eventually came out between the sink and the top of the rubber gasket… when I used less of the putty (an earlier attempt) there wasn’t enough and water eventually leaked from that area. This might fail, too. Frustrating.

    • Katherine,
      Plumber’s putty should squeeze out all around the sink strainer when you tighten up the locknut. A little of the putty may continue to ooze out for a time, but it can be easily wiped off.

  2. Yes, I understand the putty squeezing out around the top of the strainer, but should any come out under the sink, around the gasket(s)?

    • Katherine,
      Putty didn’t squeeze out around the gasket under the sink when I replaced mine, but it should still seal OK if it does.
