I was informed today that most likely next week, if not tomorrow, we will be filling in the 4" water suction hoses we used to pump water out of the ground around a hole we had to dig for a footer.  There is over a 1000' of it in the ground in 4 different sections, about 250' each.  

My questions are, how would you go about pumping this?  Using my Reed A40HP to pump it.  Only have access to one end of the plastic piping.  My thoughts were to use my 4" to 3" reducer and just dump it right into the piping.  Or use a section of 3" hose to make it a bit easier  moving from pipe to pipe, their all in about the same spot.  And how will we know its full?  

I hope you got vents in it or you want get much in the air will hold it back

Its 4" black plastic tube with holes in it and a "sock" around it burried in the ground.  There is some beathing, but not much.  I didn't even think of that, but I don't think it should be that much of a problem, just have to slow down a bit.  

run 4" line if possible and when your pump pressure spikes like your plugged its full or its stuck.......

Only have 3", 2", and a peice of crap 1 1/2" hose's.  

I usually try to go to the job the day before to glue on an adapter in needed to adapt from threaded to your pump pipe. I carry a 2" and 3" hd to pipe thread adapter. Also make mix a loose as possible. I also like to see a vent to be able to see mud come out on the other end like Ed said. Although I can see on your job that might not be possible.

good advice terry! agree that its a good idea to check out the job before hand. most of the time the threaded pipe adapters are national pipe thread (npt). so all you will need is a threaded pipe and then a ring to connect to thw thread. weld it together and your good to go

Well I know the job pretty well, been working there for a year now, and even helped put this stuff in the ground. Its black plastic garden water pipe looking thing.  You know the stuff you use to divert water away from your rain spouts.  Its just has some holes in it and a sock around it to collect the water.  So threading in a peice of pipe is out of the question.  We had put some ball valves on it to help keep air from being sucked into the pump, and all we could do was tape them up real good, like a half a roll of tape per conection.  And its a flow able fill, like a 28" slump with sand and cement.  Should flow like water.  

i just filled a 12 inch natural gas pipeline that was 730 feet long for enbridge this week.  to satisfy the engineers my boss called a hydro vac company to hookup at the ather end and pull a partial vacuum on the pipeline while i was pumping grout into it. the pipeline had dips and sags in it because it ran through the rolling hills of the countryside so using the vac truck kept all the engineers on site satisfied when the grout finally came out the other side.  we used a 3 inch heavy duty pipe welded to the pipeline to deliver the grout and then we kinked and tied off the delivery hose to seal the pipeline so that the grout could set up.  enbridge paid for all the materials used and the welding and set up time.

28 in slump from a 12 in cone!!!!!!!!!!!!!! Flow like water.  make sure you check mix design lots of fly ash helps alot
