MNBugeater: it seems like at least a few people on this thread are using, maybe not yours, but quick disconnects on a recirc type system. Was it the disconnects that were the issue as far as clogging goes, or was it maybe something else? I only ask, as I've had some issues with lautering due to compacting the grain bed. I'll get the SS versions, if it's worth it, but it doesn't seem, from the outside, that stainless vs. poly would cause clogs. If I'm wrong on that point, please let me know.
