Did not even have to start the pump

I had a sewer line to plug the other day. There was 1450 feet of 6" pipe through a graveyard they wanted plugged. They did not want me to put any pressure on the system, just wet the concrete up and let run. I explained what would happen then and suggested another material. I put my hose into the highest manhole and when the mixers arrived started my funnel job. The material is only 250psi and looks like chocolate milk. The first truck went real smooth, we saw the material pass the 2nd manhole and then I thought that when I filled up the one I was pouring in the head pressure might blow the lid off the lower hole. Suggested we get a welder real quick. After the weld was done we kept pouring until all 14 yards were in and the pipe was full. This job could not have went any better.
