cpvc plumbing

I'm replacing my water supply plumbing today with cpvc and last night when I was looking at the fittings I noticed that they said "cold water only".

I thought cpvc was good for both hot and cold?

Can anyone tell me more about cpvc?

Also, I just read that you are supposed to let the lines sit for 24 hours after gluing before pressurizing. I've always heard that pvc was good to go within minutes and assumed cpvc was the same.

Is the 24 hour wait necessary?

CPVC should be for hot, it's the smaller size and has a yellow color. Glue container should give you drying time before using, usually dependent upon temperature. .

I took a better look through the fittings and it's only the male terminal ends that say "cold water only". I have an older one and it doesn't say that.

The pipe I've got says it's fine for hot water.

I'm working around my old system (no sense in doing the easy way

) so I'm going to get all the pipe cut and glued up to the coupler before I connect to the new pump and well. Once everything is ready to rock I'll start pulling all the old system out.
