   I've only seen same size union's (3/4" - 3/4") and 1/2" - 1/2") for going from copper to cpvc. You would have to T before or after the union.

   You can get a valve too that does the same thing as the union but I have never seen or heard of a Tee.  DanT

   I don't know where you tried to get a suitable fitting, but there are many transition fittings on the market. Did you try a plumbing supply house? they should be able to solve your situation. Luck.

   Those transition fittings are not soldered directly into the line. You'd end up destroying the plastic/brass.

   Solder in a copper 3/4x3/4/1/2 tee and add a 1/2 female adapter to which you add the transition fitting or check to see if there would be a brass 3/4sx3/4s x 1/2ip tee available.

   Try Pex - once you do, you'll never use cpvc (and use minimal copper) again!

   In my experience, cpvc becomes britte with age.  Cut a newly purchased stick, and then cut one that's a few years old.  Big difference in how pliable the one is to the other.

   I use to use all copper, but now am sold on Pex - quick, clean, and even fun to install!.

   If I use PEX, is there a tee fitting made to go from copper to PEX?

   I don't know the answer to your question, but why do you need to transition with a T?

   Unless you need to do a lot of these connections, the cost of just a simple transition fitting with a T after the transition isn't that much.

   What bp2.. what's-his-name said.  The proper fitting is commonly available.  The fitting is dismantled and the metal end is sweated onto the copper line.  After it cools the fitting is reassembled and the line continued in CPVC.  Do not just use a set of male and female adapters, they will leak over time, especially on the hot water line because the thermal expansions of plastic and metal are so different that the thermal cycling will eventually cause a leak.  Any real plumbing supply house will have them.

   Why not just continue in copper, though?

   Okay, i'll ask. Why do you want to use CPVC? Go with copper or Pex, i've never heard much good about CPVC.
