What a mess

That reminds me...better check mine!

lol good idea.

I keep a yardage log on all boom pipe from tip to hopper just so this doesn't happen. Question? What would do? Call it a day and clean out turret before it sets or continue the pour and chip it out later?

Chip it out later. Not the customers fault the pipe blew. As long as it is done that day it wuldnt be TOO horrible.

How would you finish the pour? It takes like 10 minutes to clean the mess up if you do it asap. If you're lucky enough to have someone at the shop to run you over a new pipe you could easily get it all cleaned up before they even got there. 

Yes of course flush it out with water directly, then you will find old concrete on the chassis of the truck for the rest of his life. Better wait till it sets a little and then remove it.

Every old concrete pump whit strange electric problems I had to search for, most of the time I had to look for old concrete between the chassis damaging electric cables because of the movement of the chassis.  

ya thats all bad
