I have a 1/4 inch copper pipe need to go from copper to 1/2 pvpc

Hi Gosharps

I am guessing you meant CPVC? If so, then your easiest solution will be to go to home depot and purchase a 1/2" sharkbite x 1/4" compression push-fit type shutoff to make your transition... click on link below for more information:

SharkBite 1/2 in. x 1/4 in. Brass Compression Straight Stop 23337-0000 at The Home Depot

The nice thing about this shutoff is that there is no soldering or cementing involved.
