I'm almost sure there's nothing wrong with this plan, but before I commit to it, checking with people with more experience seems wise.
I'm in an area with a frost depth of less than 12". Around 24" underground is 3/4" PVC that used to supply a house that was on the property 20 years ago. Now all it feeds is an outdoor spigot next to the well house. I plan to run 3/4" 160 psi poly pipe the 60' or so to the house I'm building. Is there any problem with connecting the poly to the old PVC? The old PVC doesn't run toward the new house, so I would connect them a couple of feet in front of the well house using the brass insert to FPT adapter below with a male threaded adapter on the PVC. I could connect the poly to the piping inside the well house, but that would entail two elbows in the poly, and I would lose the outdoor spigot, which I'd like to keep, unless I also put a tee in the poly. It seems better to have just one fitting at each end of the poly than to add three more in between.
