    While breaking out my old cast iron clean out for the kitchen, I damaged the cinder block that it went through. Its still together like a puzzle, its just cracked. What are my options for repairing it? I'm also putting the new cpvc clean out back through it.

    Thanks

    if the block's hidden, just use hydraulic OR mortar to rebuild it.

    NEVER touch things that are not already broken ! ! ! :banana::clap::hide:

    I'm installing new cpvc in my house so the old clean out had to be taken out.

    If you can block off the outside surface, pump in concrete with a concrete pump; a 1" ID copper pipe with a sliding-fit dowel inserted.
    You load up the business end with a handful of concrete and then plunge it into the crevices.
