    Will condense from the boiler damage a clay drain similar to cast etc or is it perfectly safe like it is with pvc? Thanks

    It's perfectly safe as it's only a weak acid. People (including me) drip it into our septic tanks with no ill effects. The bacteria in my septic tank are doing so well it doesn't even smell with the lid off.
