I'm planning on tapping into my home water line that is supplied by a drilled well so I can run water to my barn. The barn is 350' from the house. I live in the North East so I'm digging at trench at least 4' down to bury the line. I've got a backhoe so that part of the job is pretty straightforward. I'll be installing a frost free hydrant at the barn and putting in a gravel dry well for that to drain into.
My question has to do with punching through my fieldstone foundation to get the line into my basement. I'll rent a power tool to make the hole. It will probably be a rotary drill of some sort. But once I've got the hole and put the line through it, what do I do to seal the pipe? Does it need to be sleeved? Insulated? Protected? The line is 1 1/4" ABS. Can I simply use hydrolic cement?
I would sleeve it. A piece of 1-1/2" or 2" should slide over it .Use the hydraulic cement around the sleeve. You want something with some flex between the pipe and the sleeve. Your foundation does move a bit with temperature changes and if you had cement against the plastic pipe, it could cause a leak.
If you have never made a mistake, you haven't done much.
Over the weekend I was able to start the trenching and excavated the foundation. I used a rotary hammer type drill that had both a feature that allowed either both hammer and drill or just hammer. I used the hammer more than the drill part and made a 2" hole. The foundation was about 16" wide at the point I started drilling which was about 5' down from ground level on the outside.
I took majakdragon's recommendation and put a 1.5" pvc pipe and cemented that into the hole with the cement. I'll then slide the water line through that. I suppose I should caulk that with some silicone or something to seal that but allow it to move like you say it should.
