    Accidentally cut through cold water pipe running through concrete slab
    I had a bloke core drill a hole through 200mm suspended concrete slab on body corporate space outside our bathroom. We intend to put a sewrage pipe out our wall and through the slab.

    He hit a cold water pipe going through. Luckily it was for our flat, not our neighbours. Turned off our mains. Now what?

    Do you have access to the pipe to repair, or you need to cut the slab?

    Now you chip out as much concrete as needed to cut out a short section of copper and put in a new one.
    You may have to go to a plumbing supply for the couplings that don't have the stop ridge in the middle, or you'll be there all day sanding them out so you can slide them all the back.
    (I forget the name for them - we had this happen to us.)

    Hello Joypulv,

    It is called PVC slip-coupling, or copper slip coupling, Thanks.

    And you are right about the sanding thing. If you don't have one and need one, they are worth a hundred dollars. One of the world's great inventions.
