Bet not a good day at all.Having been in close to the same senerio I understand.

Was it a mud cup they lost?

rake down the edges...

cold join? what cold join?

has anyone ever had a cup disconect from the rod / bone were to brake mid-jug?  how did you pull it out - push it out?

Stand the boom in the air while it is full of concrete, it will push the cup right back into the waterbox.  You can hook the cup back up and be pumping in 5 minutes.  Used to happen all the time on 800 and 801 Schwings with the threaded cups.

Chris you hit it right on the $$$$$$$$$$$ been there done that.

What do u mean push it back to the water box???  u telling me the force from gravity on the concrete will push the cup back too the water box??????????????????????????????????????????

Never have been there and done that
