In my basement I have copper water pipes that look like they hooked up to an old shower. Now they don't hook up to anything. I want to prune these pipes where they come off the main water line (so I can put a deep freezer in their place) but I've never done anything like that before.
Google tells me I have two options for pipe fittings: sweating or compression fittings. I want something more or less permanent but I don't to buy extra tools I may not need again for a long time, plus if I can avoid open flames I'd like to, etc. Are compression caps available and suitable for this kind of thing?
PS Can I cut copper pipe with an angle grinder or should I buy a pipe cutter?
Resolution: Thanks for all the advice! In the end I went with a pushfit cap made by SharkBite:
I also bought a handheld, handleless pipe cutter for $7. I shut off the water, cut the pipe, popped on the cap, and turned the water back on. Worked like a charm. The whole job took 20 minutes and cost about $11.
I'll look forward to learning to sweat connections another time.
