I do some plumbing repair on my own property but have trouble soldering wet pipe in a crawl space. I saw these 3/4 copper and brass compression fittings at lowes and thought these would be nice for me for capping off or breaking into a line. I familiar with compression on stops etc. and i've used galvy dresser couplings for emergency repairs on galvinized pipe.. Are these compression fittings something a respectable plumber would use and leave?? Thanks for all the help I received on this forum. HS.

Compression is intended for soft/annealed copper..like the 3/8" copper flexible feeds on a faucet.
Using them on hard copper piping isn't something I'd recommend...the joints tend to rotate when moved.
There are also a recent plethera of new types of copper connections, such as sharkbite, Tectite, Propress and others that are made to appeal to homeowners exactly in your shoes.
Soldering is tried, tested and true...once you get the hang of it it's easy.

One low-tech solution for making a soldered connection in a spot where water is an issue, is to use a union. That way, the steam from any remaining water can freely escape, and the soldering can proceed more easily.

another water removal trick

I always have vinyl tubing with Me to suck out or siphon water . A wet vac with duck tape to tubing does a great job

Thanks, I like that idea. The union too. I'm witing this all down. :D

A good idea...also a ball valve, if the flow is too heavy...put a Jetsweat through it.
