  • What to seal pipe holes with?

    Hello, I am doing a DIY plumbing job on my house and am curious about what kind of sealant the Plumbing Pros use to seal the gap in holes cut through framing members for pipes (see arrows in the attached drawing). I'm using ABS for DWV and PEX for supply/dist. I'm think of using Vulkem 116 caulk. Or would something like "Great Stuff" expanding sealant be better? What do the Pros use?

    Thanks for your time and comments.

    What is the fire rating at your penetrations if any?

      Fire Ratings ?You've exposed an area of my ignornace. Thanks. I'll have to look into that. If it helps any, this is a single level ranch style house with a attic above (nothing but insulation up there) and crawl space below. All stick construction. Can you give me a pointer on how/where to find out what the fire rating is? Thanks for the reply.

          get a tube of draft stop fire caulking from your local hardware store.
          No, it's not rocket science, it's plumbing and unlike rocket science it requires a license.

            Plumbx the fire caulking will slow down a fire that starts in a wall from going up into the attic space . with out this the fire would get up there and spread very fast with all the dry wood up there
