    They're only allowed where both ends of the pipe are well supported so that they don't shift, like buried and properly backfilled to keep them there.

    Ive used them typically underground Also I like them a littled better on crusty rough old pipe they are a little longer so I figure might be better in such situations. Ive used them under a house too going from old cast iron to plastic but might not be legal the important thing is that its alighned and supported . And of cource make sure they are aprooved

    I'm interested in this topic, because I hear so many saying they're only allowed underground, etc.

    By WI code (we do our own thing, but it's not lax standards, imo), we can use flexible couplings anywhere so long as it's "installed in accordance with the manufacturer's instructions," and Fernco allows "in home" installations on vertical pipes in their documentation. They say the pipes need to be supported, but then we fall back to our own codes regarding that.

    I haven't dug into other code to see if they say otherwise, but I'd be curious if there is a limitation specifically stated.
