Hi,

I am wondering how "safe and effective" is to use compression method
instead of soldering for joint of copper pipe and fittings? I am not
comfortable with soldering, but not sure using compression is
"water-tight enough" for joint or not, thx.

Hello:

I have a strong preference for solder. I've used an industrial type of
compression fitting in my lab with great success....but the
hardware-store type of compression fitting seems to be rather
hit-or-miss. Sometimes they work, sometimes they leak.

Suggestion: You might consider buying a few feet of 1/2" copper pipe,
a dozen solder fittings, solder, torch, tubing cutter, flux, cleaning
brush, etc.. Cut the pipe into 2"-3" lengths. Find a good book in the
library on soldering, follow the directions. Practice soldering a few
dozen joints. You will gain experience and confidence.

Cleaning is the important step.

Actually, I did practice a couple of times like you mentioned, but I
cannot tell whether the thing I solder is leaking or not. I never try
on real thing since I fail, I may end up calling emergency repair(the
thing I want to replace the valves under the sink which can not be shut
off without shutting off main valve), it may be costly than just call a
plumber to do it for me.
