I'm new to DIY projects and living in Canada. While I was drilling into my drywall to put up some drywall anchors, I hit something bouncy that felt weird when I poked it with an Allen wrench. It seems to resist drilling at about 2 to 3 inches deep, and I noticed similar resistance 2 feet away horizontally. I'm worried that I might have drilled into a PEX water pipe. How can I know for sure if I've hit a water pipe or not?

You could grab a small inspection camera; they’re pretty affordable now, around $20. Really useful for checking what's going on behind your walls without creating a big mess!
If you didn't turn off the water first and you hit a pipe, you’d probably see water leaking out. Also, if you're in a condo, you might have hit electrical conduit instead!
Yeah, sounds like it could be electrical rather than plumbing, so be cautious!
It could also be a duct. Sometimes air vents or ducts can give that bouncy feeling when you drill into them!

Totally, or you can just shove your cell phone camera against the wall to peek inside!
