Have seen 1 1/4" blue plastic stuff starting to become more and more common instead of 3/4" soft copper from curb stops and well heads to the house. Assume it is a price thing. When this stuff freezes, you can't put a welder on it like you can with copper; no continuity. I have had a bunch of calls on this this winter. I think as this stuff becomes the norm, I will get many many more. My little jetter does the job nicely, but I am concerned about contaminating water with eqipment used in drain lines. I have turned down most of these, did three. One just to see, one to verify it was really that easy, one for a buddy that just didn't care. Soaked my hose and nozzle in bleach for all. Have bought separate equipment will be for water lines only. Still concerned as it must ride in the e-coli wagon (my van) to get to the site. Any thoughts?
