Soldering a Moen shower valve

I'm new to this forum and have a question concerning the best way to solder a Moen model 62320 shower valve. Do I need to remove the cartridge? I was afraid it would get too hot and melt the o-rings. How do you know how long to heat the joint before you apply solder. It seems some of my joints are turning dark and I thought maybe I was overheating the joint. Any soldering advice would be appreciated. Thanks.

I thought most shower valves were using pipe thread these days. If your shower valve has threads and you are worried about heating it up too much then solder a length of pipe to the threaded adapter before you screw it into the fixture. Then you can use a coupling to attach this to the supply lines.

Thanks for the quick replies. The valve is not threaded and the cartridge was already installed when I got it. In addition the small white plastic tool needed to remove the cartridge wasn't included. I guess I'll have to go back to the plumbing supply house and get one. Your advice on how to solder has helped me get a better result. I never realized how difficult it was ... kind of like playing golf ..... how hard can it be to hit that little ball???? Anyway thanks again , I'm sure I'll have more questions when I try to install my Aquaglass 3-piece shower , Toto Drake toilet , and vanity in my basement project.

If new to soldering a MAPP gas torch can help a bit. It is hotter than propane and gets things moving along pretty well.
