soldering copper to brass?
my plumber cut a brass pipe which had a nipple at the end so it was thicker than the copper coupling. He sanded it down to make the copper fit and then soldered it. Did anyone ever hear of this and do i need to worry about it leaking?

It is fine, if it didn't leak when he pressurized the system, it most likely will never leak.

What is this valve made of ?
You'll probably find a dozen or so joints sweated between copper and brass in your home.

They are Join freindly because of the amount of copper content in brass. Some people have problems getting the solder to take when mixing metals but it's because of over heating the copper as the brass takes a little longer to heat up than the copper. But if he's a proper plumber it will be fine.

thats hack! the codes states the use of approved fittings sanding and modifying a brass nipple and soldering a coupling to it is not approved sure it works but is just wrong he could have sweated on some fip adapters and threaded to the brass nipple.

I dont think he cares that he didnt use an "approved" fitting but wants to know if the soldering from brass to copper was ok. I wouldnt give a dam as long as it was fine after a pressure test.

I was told by a building inspector once that i couldn't use brass olives on compression fittings. He didn't have a reason as to why so i had to explain to him why i didn't use brass olives anyway and swapped them out for copper. The idiot didn't even know the reason why you wernt meant to use brass. Some of these codes are just stupid.

Yup Moraga near Orinda but I own multiple residential apartment bldgs in the city. I work in the city too and some inspectors seem to have a strong preference for particular fire protection firms to have "no hassle" inspections. I deal with DBI often enough and they are a bunch of bottom feeding homosexual blowers.

Nope i mean olive. You normally get them with brass olive but they have to be strangled so much that you cant ever get them of the pipe and they can be over tightened. I just change them all out with copper and never have the issues involved with brass versions. Most good quality fittings will come with a copper olive for this exact reason. But some of thr cheaper ones just bundle brass.
