When you put a new pipe into a new fitting and apply solder, how can you be
sure that the solder is bonded properly? You can make sure it looks good on
the outside, but that's no guarantee the inside looks just as good. There
could be a bare spot inside, making it a weak joint.
Would it be better to apply solder to the pipe and fitting separately, then
put them together? I don't think many people do it this way though.

Hi,
First parts to be soldered should be CLEAN, and you apply flux, the
solder flows by capillary action when heated.
Applying solder on each part and put them together? Why don't you try
it? I can tell, it's impossible, LOL. Sounds like you never did soldering.

Yes, tinning the joint can assure better contact, but it is not necessary.
There are probably tens of billions of joints done by sweating and they have
not failed. You just have to practice. Why add another step after all these
years of good copper plumbing?

Go to HD and get some of their EZ-Sweat fittings. The solder is
already inside the fitting forming a perfect ring. Just add flux to
your pipe, insert, and heat. Everyone I have used creates a perfect
joint every time and it's a lot easier than doing the solder yourself
(especially in tight spaces).

Funny thing. My dad is a plumber and we just sweated a bunch of joints in
remodeling our bathrooms. We were were talking about how the fitting with
solder in them dont work. When at our local HD, they had all the EZ Sweat
fitting marked down for clearance.
Guess that says they sell a lot of them.
