Miscellaneous Plumbing Questions

I have 2 plumbing questions, if someone could please answer them:
1. Is there a copper sweat fitting that can be used (sweated) to splice directly into 1/2" bronze water supply lines? These bronze supply lines are threaded. I wanted to use regular 1/2" copper without having to unscrew the long bronze line at the joint and then adapting with a thread-sweat 1/2" adapter (it's ashamed to waste/replace all that beautiful length of bronze piping with copper).

2. The caulking around my vanity and kitchen sink become moldy. I used a GE silicone caulking when I installed the sinks about 2 years ago. Is there a particular caulking that you've found good against this molding problem?

Thanks in Advance,
EDTA

1) You can cut & thead the pipe, then go copper from there. It should be fairly easy to hand thread. I've never seen a fitting that would let you solder directly to brass pipe.

2) If anyone is aware of caulking that will never mildew, please let us both know about it. You can clean off mildew with diluted bleach. Wear gloves.

Miscellaneous Plumbing Questions

Thank you Steve Gro for the suggestion; unfortunately, I do not have a pipe threader.
What do you about cutting a section out and splicing in a 3/4"X3/4"X1/2" tee? A piece of brass pipe fits pretty sloppy in the 3/4" and I sure would hate to sweat it all into place, turn on the water and find it leaks (in which case, I mind as well just disconnected at nearest threaded joints--yes I do have monkey wrenches--and adapted to the 1/2" copper).

Thanks,
EDTA

You may be comparing apples and oranges.

Most copper tubing used in plumbing 1/2" and 3/4" is rated for inside diameter. You should check out HVAC copper fittings. Same size rating but 1/8" smaller. 1/2" is 1/2" outside diameter with 7/16" interior. Same applies to 3/4".

Just a thought....

If you were to find a copper fitting that would fit over the brass pipe, the transition wouldn't be right; it may pinhole after a while. I'm sorry to say that I don't see an alternative to cutting & threading or going back to the last fitting. It probably doesn't cost much to rent a threader though.
