look at this thing. i had 250 feet of 2 1/2 hose pumping away when right as i hear it starting to back up i turn pump off but it was to late. this is what shot out the end of my hose.

Looks like you need to use bigger hose, lol

if these damn ready mix plants/drivers/etc would just bring the stuff they are asked to bring and nothing else issues like this wouldnt happen lolz. these are the types of added extra bonus for your buck you dont want

Ya know,I thought that very same thing for so long.That\'s when I learned the truth.These rocks (which you found) most likely arrived to the plant from the pit.That\'s right there supplier.

I for one wouldn\'t want to pay a guy to watch every stone that went into the bins.So what do you have for back up,the mixer driver,your grate and that\'s about it.I know how frustrating it is but that\'s why we make the big bucks.Good luck.
