You would need access to a threaded part of the galv pipe. Either male or female. Then screw on the proper CPVC adapter.

Your not using PVC are you? Potable water?

CPVC to Galvanized

I would suggest female galvanized and male CPVC. A female CPVC on a galvanized male will split if screwed on too tight.

This is assuming you're tying into a supply line. If it's for a drain/vent, you can use a no-hub coupling (a rubber coupling with a metal shield and hose clamps to secure it).

i am using pvc for portable water. I know some people are under the impression that code doesnt allow it, but i have already spoken with my city plumbing inspector, a local plumber and the dude working at lowes and they all confirm that its perfectly legal (at least here) to use pvc for COLD water distribution. Also, 90% of the homes in my neighborhood have pvc water lines.

Same here. CPVC is usually only used on the hot side.

i was told that pvc can only be used for cold water and drainage and that cpvc is required for hot water but optional for cold as well.

IMO I would not use cpvc or pvc.....Expansion issues... There was a class action lawsuit against flo gaurd gold I believe in the past. Would have to look it up. Why have multiple pipe materials??

I would opt for pex, period!
