Jo: We use a Sears Craftsman shop vac, 16 gal, & I really don't know the HP. We use the Greenlee pistons (mice)and the Greenlee nylon string. (comes out the middle of the spool) I have never tried the baggie trick, but I may on the next job. We just finished eight UG PVC pulls (180' to 340' 1-1/4 and 2" Sch 80) and had no problems with the vac or pistons)
Ok....the greenlee 'lil fisher blows the pistons through the pipe. From reading this thread I'm getting the idea that most of you prefer to suck a baggie and fish line through.....correct????
Ya GJ, but i've used the greenlee's too, they push out a good volume of H2O given a proper seal at the vac end. Usually quite the surprise for the apprentice's....
