BladeRunner: Are we seeing a pattern in most of the replies here?? like I'd indicated in your disaster thread, user error in one form or another seems to be the most common factor from what I've seen here and generally.

Yes BR, I'm seeing lots of patterns including the UE that you mentioned (whether the immediate cause, or a design failure that occurred later)
I'm very glad that I put this survey up, I think that it's a useful collection of information that shows lots of things BESIDES the somewhat expected User Error. (I've been watching the replies as they came in, but not commenting as I didn't want to skew the results....)
Slow leaks from various places seem to be the biggest class of problems, but there don't seem to be many major floods. Arguably this is the class with the fewest direct UE's as direct cause, though most could be argued as UE indirectly.
Somewhat to my surprise, pumps seemed to be another major problem area. Some problems were direct UE (didn't turn on) but there also were more pump functional failures than I would have expected. (makes me glad I got an Iwaki)
I didn't like seeing all the 'Other' responses, but it seems to me like most of those were related to radical cooling failures, which I had deliberately not included.
I also decided to allow multiple choice responses, which may have been a bad choice on my part, though I thought it was best at the time I did the poll. It is interesting to note that 'never had a problem' and any of the major 'had problem' responses total to more than the number of messages in the thread...
Guess this means there were voters who didn't leave messages, or possibly someone's fibbing...
I hope this survey either gets made into a sticky, or an article is created from it, as it taught me things that I haven't seen expressed elsewhere, namely the types of things that actually DO go wrong (Note that we have only had one (so far at least) CPU / Block separation, which wasn't talked about. This was one of the things I had feared most, but now feel much less worried about.)
Indeed most of the things I mentioned didn't get much response, especially the more dramatic failures. Pumps seem to go out or not get turned on alot (which shows the need to have a fail safe to ensure they are turned on, and the flow monitored) and we have lots of slow drippy leaks, which seem to be hard to catch, but not do a great deal of expensive damage otherwise. (shows need for good sealing and clamping practices)
